SAFETY PRECAUTIONS
(Read these precautions before using)

When using Mitsubishi equipment, thoroughly read this manual and the related
manuals introduced in this manual. Also pay careful attention to safety and
handle the module correctly.
These SAFETY PRECAUTIONS classify the safety precautions into two
categories: "DANGER" and "CAUTION".

DANGER

CAUTION

Procedures which may lead to a dangerous condition
and cause death or serious injury if not carried out
correctly.
Procedures which may lead to a dangerous condition
and cause superficial to medium injury, or physical
damage only, if not carried out correctly.

Depending on circumstances, procedures indicated by
CAUTION may also
cause serious accidents.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it
whenever necessary. Always forward it to the end user.

A-1

[DESIGN PRECAUTIONS]
DANGER
Install a safety circuit external to the PLC that keeps the entire system safe
even when there are problems with the external power supply or the PLC
module. Otherwise, trouble could result from erroneous output or
erroneous operation.
(1) Outside the PLC, construct mechanical damage preventing interlock
circuits such as emergency stop, protective circuits, positioning upper
and lower limits switches and interlocking forward/reverse operations.
(2) When the PLC detects the following problems, it will stop calculation and
turn off all output in the case of (a).
In the case of (b), it will stop calculation and hold or turn off all output
according to the parameter setting.
Note that the AnS series module will turn off the output in either of cases
(a) and (b).
(a) The power supply module has over currentprotection equipment and
over voltage protection equipment.
(b) The CPU module self-diagnosis functions, such as the watch dog
timer error, detect problems.
In addition, all outputs will be turned on when there are problems that
the CPU module cannot detect, such as in the I/O controller. Build a
fail-safe circuit or provide a mechanism exterior to the PLC that will
make sure the equipment operates safely at such times. For a failsafe circuit example, see "Loading and Installation" in this manual.
(3) Output could be left on or off when there is trouble in the outputs module
relay or transistor. So build an external monitoring circuit that will monitor
any single outputs that could cause serious trouble.
When overcurrent which exceeds the rating or caused by short-circuited
load flows in the output module for a long time, it may cause smoke or fire.
To prevent this, configure an external safety circuit, such as fuse.
Build a circuit that turns on the external power supply when the PLC main
module power is turned on. If the external power supply is turned on first, it
could result in erroneous output or erroneous operation.

A-2

[DESIGN PRECAUTIONS]
DANGER
When there are communication problems with the data link, refer to the
corresponding data link manual for the operating status of each station. Not
doing so could result in erroneous output or erroneous operation.
When connecting a peripheral device to the CPU module or connecting a
personal computer or the like to the intelligent function module to exercise
control (data change) on the running PLC, configure up an interlock circuit
in the sequence program to ensure that the whole system will always
operate safely.
Also before exercising other control (program change, operating status
change (status control)) on the running PLC, read the manual carefully and
fully confirm safety.
Especially for the above control on the remote PLC from an external
device, an immediate action may not be taken for PLC trouble due to a
data communication fault.
In addition to configuring up the interlock circuit in the sequence program,
corrective and other actions to be taken as a system for the occurrence of
a data communication fault should be predetermined between the external
device and CPU module.

CAUTION
Do not bunch the control wires or communication cables with the main
circuit or power wires, or install them close to each other. They should be
installed 100 mm (3.94 inch) or more from each other. Not doing so could
result in noise that would cause erroneous operation.
When controlling items like lamp load, heater or solenoid valve using an
output module, large current (approximately ten times greater than that
present in normal circumstances) may flow when the output is turned OFF
to ON.
Take measures such as replacing the module with one having sufficient
rated current.

A-3

[INSTALLATION PRECAUTIONS]
CAUTION
Use the PLC in an environment that meets the general specifications
contained in this manual. Using this PLC in an environment outside the
range of the general specifications could result in electric shock, fire,
erroneous operation, and damage to or deterioration of the product.
Hold down the module mounting lever at the module bottom, and securely
insert the module fixing latch into the fixing hole in the base unit. Incorrect
mounting of the module can cause a malfunction, failure or drop.
When using the PLC in the environment of much vibration, tighten the
module with a screw.
Tighten the screw in the specified torque range. Undertightening can cause
a drop, short circuit or malfunction. Overtightening can cause a drop, short
circuit or malfunction due to damage to the screw or module.
When installing extension cables, be sure that the connectors of base unit
are installed correctly. After installation, check them for looseness. Poor
connections could cause an input or output failure.
Securely mount the memory card into the memory card mounting
connector. After mounting, check for lifting. Lifting can cause a malfunction
due to a contact fault.
Completely turn off the external power supply before mounting or removing
the module. Not doing so could result in electric shock or damage to the
product.
Note that online module change can be made when the QnPHCPU is used.
Note that there are restrictions on the modules that can be changed online
and each module has a predetermined changing procedure.
For details, refer to the section of online module change in the Process
CPU User's Manual (Hardware Design,Maintenance and Inspection).
Do not directly touch the module's conductive parts or electronic
components. Touching the conductive parts could cause an operation
failure or give damage to the module.

A-4

[WIRING PRECAUTIONS]
DANGER
Completely turn off the external power supply when installing or placing
wiring. Not completely turning off all power could result in electric shock or
damage to the product.
When turning on the power supply or operating the module after installation
or wiring work, be sure that the module's terminal covers are correctly
attached. Not attaching the terminal cover could result in electric shock.

CAUTION
Be sure to ground the FG terminals and LG terminals to the protective
ground conductor. Not doing so could result in electric shock or erroneous
operation.
When wiring in the PLC, be sure that it is done correctly by checking the
product's rated voltage and the terminal layout. Connecting a power supply
that is different from the rating or incorrectly wiring the product could result
in fire or damage.
External connections shall be crimped or pressure welded with the
specified tools, or correctly soldered. Imperfect connections could result in
short circuit, fires, or erroneous operation.
Tighten the terminal screws with the specified torque. If the terminal screws
are loose, it could result in short circuits, fire, or erroneous operation.
Tightening the terminal screws too far may cause damages to the screws
and/or the module, resulting in fallout, short circuits, or malfunction.
Be sure there are no foreign substances such as sawdust or wiring debris
inside the module. Such debris could cause fires, damage, or erroneous
operation.
The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.

A-5

[STARTUP AND MAINTENANCE PRECAUTIONS]
DANGER
Do not touch the terminals while power is on.
Doing so could cause shock or erroneous operation.
Correctly connect the battery. Also, do not charge, disassemble, heat,
place in fire, short circuit, or solder the battery. Mishandling of battery can
cause overheating or cracks which could result in injury and fires.
Switch all phases of the external power supply off when cleaning the
module or retightening the terminal or module mounting screws. Not doing
so could result in electric shock.
Undertightening of terminal screws can cause a short circuit or malfunction.
Overtightening of screws can cause damages to the screws and/or the
module, resulting in fallout, short circuits, or malfunction.

CAUTION
The online operations conducted for the CPU module being operated,
connecting the peripheral device (especially, when changing data or
operation status), shall be conducted after the manual has been carefully
read and a sufficient check of safety has been conducted.
Operation mistakes could cause damage or problems with of the module.
Do not disassemble or modify the modules.
Doing so could cause trouble, erroneous operation, injury, or fire.
Use any radio communication device such as a cellular phone or a PHS
phone more than 25cm (9.85 inch) away from the PLC.
Not doing so can cause a malfunction.
Completely turn off the external power supply before loading or unloading
the module. Not doing so could result in electric shock or damage to the
product.
Note that online module change can be made when the QnPHCPU is used.
Note that there are restrictions on the modules that can be changed online
and each module has a predetermined changing procedure.
For details, refer to the section of online module change in the Process
CPU User's Manual (Hardware Design,Maintenance and Inspection).
Be sure not make a strong impact on the battery to be mounted into the
module by dropping or similar careless action. This could break the battery,
causing an internal battery liquid leakage.
Do not use the battery which has been exposed to a strong impact, and
dispose of it.

POINT
*1 : Overcurrent protection
The overcurrent protection device shuts off the 5 V, 24 VDC circuit and
stops the system if the current flowing in the circuit exceeds the specified
value. If this device is activated, switch the input power supply off and
eliminate the cause such as insufficient current capacity or short. Then, a
few minutes later, switch it on to restart the system.
The initial start for the system takes place when the current value
becomes normal.
*2 : Overvoltage protection
The overvoltage protection device shuts off the 5 VDC circuit and stops
the system if a voltage of 5.5 to 6.5 VDC is applied to the circuit. When
this device is activated, the power supply module LED is switched OFF. If
this happens, switch the input power OFF, then a few minutes later ON.
This causes the initial start for the system to take place. The power
supply module must be changed if the system is not booted and the LED
remains OFF.
*3 : Allowable momentary power failure period
(1) For AC input power supply
y An instantaneous power failure lasting less than 20ms will cause
AC down to be detected, but operation will continue.
y An instantaneous power failure lasting more than 20ms may cause
the operation to continue or initial start to take place depending on
the power supply load.
Furthermore, by using the same AC power supply for the AC input
module and the power supply module, it is possible to prevent the
sensor, to which the AC input module is connected, from turning
OFF when it is ON when the power is turned OFF.
However, if only the AC input module is connected to the AC line,
which is connected to the power suppludetection of the AC down
for the power supply module may be delayed by the capacitor in
the AC input module. Thus, connect a load of approx. 30mA per
QX10 unit to the AC line.
(2) For DC input power supply
y An instantaneous power failure lasting less than 10ms (*4) will
cause 24VDC down to be detected, but operation will continue.
y An instantaneous power failure lasting more than 10ms (*4) may
cause the operation to continue or initial start to take place
depending on the power supply load.
(*4: This is for a 24VDC input. This is 10ms or less for 24VDC or less.)

3. EMC and Low Voltage Directive
For the products sold in European countries, the conformance to the EMC
Directive, which is one of the European Directives, has been a legal obligation
since 1996. Also, conformance to the Low Voltage Directive, another European
Directives, has been a legal obligation since 1997.
Manufacturers who recognize their products must conform to the EMC and Low
Voltage Directive are required to declare that their products conform to these
Directives and put a "CE mark" on their products.
3.1 Requirements for conformance to EMC Directive
The EMC Directive specifies that products placed on the market must "be so
constructed that they do not cause excessive electromagnetic interference
(emissions) and are not unduly affected by electromagnetic interference
(immunity) ". The applicable products are requested to meet these
requirements. The sections 3.1.1 through 3.1.6 summarize the precautions on
conformance to the EMC Directive of the machinery constructed using the
MELSEC-Q series PLCs.
The details of these precautions has been prepared based on the control
requirements and the applicable standards . However, we will not assure that
the overall machinery manufactured according to these details conforms to the
above-mentioned directives. The method of conformance to the EMC Directive
and the judgment on whether or not the machinery conforms to the EMC
Directive must be determined finally by the manufacturer of the machinery.

*1: QP : Quasi-peak value, Mean : Average value
*2: The PLC is an open type device (device installed to another device) and
must be installed in a conductive control panel.
The tests for the corresponding items were performed while the PLC was
installed inside a control panel.

3.1.2 Installation instructions for EMC Directive
The PLC is open equipment and must be installed within a control cabinet for
use. This not only ensures safety but also ensures effective shielding of PLCgenerated electromagnetic noise.
(1) Control cabinet
(a) Use a conductive control cabinet.
(b) When attaching the control cabinet's top plate or base plate, mask
painting and weld so that good surface contact can be made between
the cabinet and plate.
(c) To ensure good electrical contact with the control cabinet, mask the
paint on the installation bolts of the inner plate in the control cabinet so
that contact between surfaces can be ensured over the widest
possible area.
(d) Earth the control cabinet with a thick wire so that a low impedance
connection to ground can be ensured even at high frequencies.
(e) Holes made in the control cabinet must be 10 cm (3.94 inch) diameter
or less. If the holes are 10 cm (3.94 inch) or larger, radio frequency
noise may be emitted.
In addition, because radio waves leak through a clearance between
the control panel door and the main unit, reduce the clearance as
much as practicable.
The leakage of radio waves can be suppressed by the direct
application of an EMI gasket on the paint surface.
Our tests have been carried out on a panel having the damping
characteristics of 37 dB max. and 30 dB mean (measured by 3 m
method with 30 to 300MHz).
(2) Connection of power and earth wires
Earthing and power supply wires for the PLC system must be connected
as described below.
(a) Provide an earthing point near the power supply module. Earth the
power supply's LG and FG terminals (LG : Line Ground, FG : Frame
Ground) with the thickest and shortest wire possible. (The wire length
must be 30 cm (11.18 inch) or shorter.) The LG and FG terminals
function is to pass the noise generated in the PLC system to the
ground, so an impedance that is as low as possible must be ensured.
As the wires are used to relieve the noise, the wire itself carries a
large noise content and thus short wiring means that the wire is
prevented from acting as an antenna.
(b) The earth wire led from the earthing point must be twisted with the
power supply wires. By twisting with the earthing wire, noise flowing
from the power supply wires can be relieved to the earthing. However,
if a filter is installed on the power supply wires, the wires and the
earthing wire may not need to be twisted.

3.1.3 Cables
The cables extracted from the control panel contain a high frequency noise
component. On the outside of the control panel, therefore, they serve as
antennas to emit noise. To prevent noise emission, use shielded cable for the
cables which are connected to the I/O units and intelligent function units and
may be extracted to the outside of the control panel.
The use of a shielded cable also increases noise resistance. The signal lines
connected to the PLC I/O units and intelligent function units use shielded
cables to assure noise resistance under the conditions where the shield is
earthed. If a shielded cable is not used or not earthed correctly, the noise
resistance will not meet the specified requirements.
When the shield of a shielded cable is earthed to the cabinet body, please
ensure that the shield contact with the body is over a large surface area. If the
cabinet body is painted it will be necessary to remove paint from the contact
area. All fastenings must be metallic and the shield and earthing contact must
be made over the largest available surface area. If the contact surfaces are too
uneven for optimal contact to be made either use washers to correct for surface
inconsistencies or use an abrasive to level the surfaces. The following diagrams
show examples of how to provide good surface contact of shield earthing by
use of a cable clamp.
(1) Earthing of shielded of shield cable
(a) Earth the shield of the shielded cable as near the unit as possible
taking care so that the earthed cables are not induced
electromagnetically by the cable to be earthed.
(b) Take appropriate measures so that the shield section of the shielded
cable from which the outer cover was partly removed for exposure is
earthed to the control panel on an increased contact surface. A clamp
may also be used as shown in the figure below. In this case, however,
apply a cover to the painted inner wall surface of the control panel
which comes in contact with the clamp.

Note) The method of earthing by soldering a wire onto the shield section
of the shielded cable as shown below is not recommended. The
high frequency impedance will increase and the shield will be
ineffective.

(2) MELSECNET/H module
Always use a double-shielded coaxial cable (MITSUBISHI CABLE
INDUSTRIES, LED.: 5C-2V-CCY) for the coaxial cables MELSECNET/H
module. Radiated noise in the range of 30MHz or higher can be
suppressed by use of the double-shielded coaxial cables. Earth the
double-shielded coaxial cable by connecting its outer shield to the ground.

(3) Ethernet module, FL-net module, Web server module
Precautions for using AUI cables, twisted pair cables and coaxial cables
are described below.
(a) Always earth the AUI cables connected to the 10BASE5 connectors.
Because the AUI cable is of the shielded type, strip part of the outer
cover and earth the exposed shield section to the ground on the
widest contact surface as shown below.

pair cables, strip part of the outer cover and earth the exposed shield
section to the ground on the widest contact surface as shown below.

(4) I/O signal lines and other communication cables
For the I/O signal lines and other communication lines (RS-232, RS-422,
CC-Link, etc.), if extracted to the outside of the control panel, also ensure
to earth the shield section of these lines and cables in the same manner
as in item (1) above.

3.1.4 Power supply module
Always ground the LG and FG terminals after short-circuiting them.

(a) Earthing of shielded cables
• Earth the shield of the shielded cable as near the unit as possible
taking care so that the earthed cables are not induced
electromagnetically by the cable to be earthed.
• Take appropriate measures so the shield that was partly removed
for exposure is earthed to the control panel over a large contact
surface area. A clamp may also be used as shown in the figure
below. In this case, however, apply a cover to the painted inner wall
surface of the control panel which comes in contact with the clamp.

(d) I/O signal lines and other communication cables
For the I/O signal lines extracted to the outside of the control panel,
also ensure to earth the shield section of these lines and cables in the
same manner as in item (1) above.
(2) Power supply module
The precautions required for each power supply module are described
below. Always observe the items noted as precautions.

Precautions
Not usable
Use the 24VDC panel power equipment conforming to the
CE Directives.
Always ground the LG and FG terminals after shortcircuiting them.

*1: If sufficient filter circuitry is built into the 24 VDC external power supply
module, the noise generated by A1S63P will be absorbed by that filter
circuit, so a line filter may not be required.
Filtering circuitry of version F or later of A1S63P is improved so that a
external line filter is not required.
24

3.1.6 Others
(1) Ferrite core
A ferrite core has the effect of reducing radiated noise in the 30MHz to
100MHz band.
It is not required to fit ferrite cores to cables, but it is recommended to fit
ferrite cores if shield cables pulled out of the enclosure do not provide
sufficient shielding effects.
It should be noted that the ferrite cores should be fitted to the cables in the
position immediately before they are pulled out of the enclosure. If the
fitting position is improper, the ferrite will not produce any effect.
In the CC-Link system, however, ferrite cores cannot be fitted to cables.
(2) Noise filter (power supply line filter)
A noise filter is a component which has an effect on conducted noise.
It is not required to fit the noise filter to the power supply line, but fitting it
can further suppress noise.
(The noise filter has the effect of reducing conducted noise of 10MHz or
less.)
The precautions required when installing a noise filter are described
below.
1) Do not bundle the wires on the input side and output side of the noise
filter. When they are bundled, the output side noise will induct into the
input side wires.

3.2 Requirement to Conform to the Low Voltage Directive
The Low Voltage Directive requires each device that operates with the power
supply ranging from 50 to 1000VAC and 75 to 1500VDC to satisfy the safety
requirements.
In Sections 3.2.1 to 3.2.6, cautions on installation and wiring of the MELSEC-Q
series PLC to conform to the Low Voltage Directive are described.
We have put the maximum effort to develop this material based on the
requirements and standards of the regulation that we have collected. However,
compatibility of the devices which are fabricated according to the contents of
this manual to the above regulation is not guaranteed. Each manufacturer who
fabricates such device should make the final judgement about the application
method of the Low Voltage Directive and the product compatibility.
3.2.1 Standard applied for MELSEC-Q series PLC
The standard applied for MELSEC-Q series PLC is EN61010-1 safety of
devices used in measurement rooms, control rooms, or laboratories.
The MELSEC-Q series modules which operate at the rated voltage of
50VAC/75VDC or above are also developed to conform to the above standard.
The modules which operate at the rated voltage of less than 50VAC/75VDC are
out of the Low Voltage Directive application range.
3.2.2 PLC selection
(1) Power supply module
There are dangerous voltages (voltages higher than 42.4V peak) inside
the power supply modules of the 100/200VAC rated I/O voltages.
Therefore, the CE marked models are enhanced in insulation internally
between the primary and secondary.
(2) I/O module
There are dangerous voltages in the I/O modules of the 100/200VAC
rated I/O voltages. Therefore, the CE marked models are enhanced in
insulation internally between the primary and secondary.
The I/O modules of 24VDC or less rating are out of Low Voltage Directive
application range.
(3) CPU module, memory card, base unit
Using 5VDC circuits inside, the above modules are out of the Low Voltage
Directive application range.
(4) Intelligent function modules (special function modules)
The intelligent function modules (special function modules) such as the
analog, network and positioning modules are 24VDC or less in rated
voltage and are therefore out of the Low Voltage Directive application
range.
(5) Display device
Use the CE marked display device.

3.2.3 Power supply
The insulation specification of the power supply module was designed assuming
installation category II. Be sure to use the installation category II power supply to the PLC.
The installation category indicates the durability level against surge voltage generated
by a thunderbolt. Category I has the lowest durability; category IV has the highest
durability.

Category IV

Category III

Category II

Category I

Figure 1. : Installation Category
Category II indicates a power supply whose voltage has been reduced by two or
more levels of isolating transformers from the public power distribution.
3.2.4 Control panel
Because the PLC is an open device (a device designed to be stored within
another module), be sure to use it after storing in the control panel.
(1) Electrical shock prevention
In order to prevent persons who are not familiar with the electric facility such as
the operators from electric shocks, the control panel must have the following
functions :
(a) The control panel must be equipped with a lock so that only the
personnel who has studied about the electric facility and have enough
knowledge can open it.
(b) The control panel must have a structure which automatically stops the
power supply when the panel is opened.
(2) Dustproof and waterproof features
The control panel also has the dustproof and waterproof functions. Insufficient
dustproof and waterproof features lower the insulation withstand voltage, resulting
in insulation destruction. The insulation in our PLC is designed to cope with the
pollution level 2, so use in an environment with pollustion level 2 or below.
Pollution level 1: An environment where the air is dry and conductive dust
does not exist.
Pollution level 2: An environment where conductive dust does not usually
exist, but occasional temporary conductivity occurs due to
the accumulated dust. Generally, this is the level for inside
the control panel equivalent to IP54 in a control room or on
the floor of a typical factory.
Pollution level 3: An environment where conductive dust exits and conductivity
may be generated due to the accumulated dust.
An environment for a typical factory floor.
Pollution level 4: Continuous conductivity may occur due to rain, snow, etc. An
outdoor environment.
As shown above, the PLC can realize the pollution level 2 when stored in
a control panel equivalent to IP54.

3.2.5 Grounding
There are the following two different grounding terminals. Use either grounding
terminal in an earthed status.

3.2.6 External wiring
(1) 24 VDC external power supply
For the MELSEC-Q series 24VDC I/O modules and the intelligent function
modules (special function modules) which require external supply power,
(2) External devices
When a device with a hazardous voltage circuit is externally connected to
the PLC, use a model whose circuit section of the interface to the PLC is
intensively insulated from the hazardous voltage circuit.
(3) Intensive insulation
Intensive insulation refers to the insulation with the dielectric withstand
voltage shown in Table 1.

4. Mounting and Installation
4.1 Module Installation
4.1.1 Handling instructions

CAUTION

z Use the PLC in an environment that meets the general
specifications contained in this manual. Using this
PLC in an environment outside the range of the
general specifications could result in electric shock,
fire, erroneous operation, and damage to or
deterioration of the product.
z Hold down the module mounting lever at the module
bottom, and securely insert the module fixing latch into
the fixing hole in the base unit. Incorrect mounting of
the module can cause a malfunction, failure or drop.
When using the PLC in the environment of much
vibration, tighten the module with a screw.
Tighten the screw in the specified torque range.
Undertightening can cause a drop, short circuit or
malfunction. Overtightening can cause a drop, short
circuit or malfunction due to damage to the screw or
module.
z When installing extension cables, be sure that the
connectors of base unit are installed correctly.
After installation, check them for looseness. Poor
connections could cause an input or output failure.
z Securely mount the memory card by pushing it into the
memory card mounting slot. Then, confirm that it has
been securely mounted. Not doing so can cause a
malfunction due to a contact fault.
z Completely turn off the external power supply before
mounting or removing the module. Not doing so could
result in electric shock or damage to the product.
Note that online module change can be made when
the QnPHCPU is used.
Note that there are restrictions on the modules that
can be changed online and each module has a
predetermined changing procedure.
For details, refer to the section of online module
change in the Process CPU User's Manual (Hardware
Design,Maintenance and Inspection).
z Do not directly touch the module's conductive parts or
electronic components. Touching the conductive parts
could cause an operation failure or give damage to the
module.

This section provides instructions for handling the CPU, I/O, intelligent function
and power supply modules, base units and so on.
(1) Module enclosure, memory card, terminal block connectors and pin
connectors are made of resin; do not drop them or subject them to strong
impact.
(2) Do not remove modules' printed circuit boards from the enclosure in order
to avoid changes in operation.
(3) Tighten the module mounting and fixing screws as specified below.

(4) Make sure to install the power supply module on the extension base units
Q6 B, QA1S6 B. Even if the power supply module is not installed, when
the I/O modules and intelligent function module installed on the base units
are of light load type, the modules may be operated. In the case, because
a voltage becomes unstable, we cannot guarantee the operation.
(5) When using an extension cable, do not bundle it with nor run it close to
the main circuit (high voltage, large current) cables.

4.1.2 Instructions for mounting the base unit

4.1.4 Setting the extension stage number of the extension base unit
When using two or more extension base units, their extension stage numbers
must be set with the extension stage number setting connectors. Extension 1
need not be set since the extension stage number is factory-set to 1.
Make this setting in the following procedure.
(1) The extension stage number setting connector of the extension base unit
is located under the IN side base cover.
First, loosen the upper and lower screws in the IN side base cover and
remove the base cover from the extension base unit.

(2) Insert the connector pin in the required extension number location of the
connector (PIN1) existing between the IN and OUT sides of the extension
cable connector.

POINT
(1) Set the extension stage number setting connector to any of numbers 1 to
7 in ascending order.
If two or more modules have the same number or any module has no
setting, for example, false input and output will occur.
(2) If there are Q5 B/Q6 B and QA1S6 B extension base units, first set the
extension stage numbers of the Q5 B/Q6 B's. (The Q00J/Q00/Q01CPU
or Q12PH/Q25PHCPU cannot use the QA1S6 B.)
Example: When there are a total of seven extension base units, four
Q68B's and three QA1S68B's, set numbers 1 to 4 to the Q68B's
and numbers 5 to 7 to the QA1S68B's.
For the extension base connection sequence, connect the
Q5 B/Q6 B's, then connect the QA1S6 B's.

(3) Mount the base cover to the extension base unit and tighten the base
cover screw.
(Tightening torque: 36 to 48Nxcm)

4.1.5 Connecting and disconnecting extension cable
(1) Instructions for handling an extension cable
• Do not stamp an extension cable.
• An extension cable must be connected to the base unit when the base
cover has been installed.
(After you have set the extension number to the extension base unit,
reinstall and screw the base cover.)
• When running an extension cable, the minimum bending radius of the
cable should be 55mm (2.17 inch) or more.
If it is less than 55mm (2.17 inch), a malfunction may occur due to
characteristic deterioration, open cable or the like.
• When connecting or disconnecting an extension cable, do not hold the
ferrite cores mounted at both ends of the cable.
Hold the connector part of the cable for connection or disconnection.

Holding the ferrite core may cause the cable to open within the connector.
Also, if the ferrite core is shifted, the characteristic will change. When
handling the cable, take care not to shift the ferrite core positions.

(2) Connecting of extension cable
POINT
When connecting an extension base unit to the main base unit with an
extension cable, always plug the OUT side connector of the main base unit
and the IN side connector of the extension base unit with an extension
cable. The system will not operate properly if the extension cable is
connected in the form of IN to IN, OUT to OUT or IN to OUT.
When connecting two or more extension base units, plug the OUT side
connector of the first extension base unit and the IN side connector of the
second extension base unit with an extension cable.
(a) To connect an extension cable to the main base unit, remove the
portion under the OUT characters on the base cover with a tool such
as a flat-blade screwdriver (5.5 75, 6 100). This also applies to a
case where an extension cable is connected to the OUT side
connector of the extension base unit.
When plugging the extension cable to the Q00JCPU, remove the
cover of the extension cable connector by hand.

the extension cable after making sure that the fixing screws have been
removed completely.

4.2 General Safety Requirements

DANGER

z Install a safety circuit external to the PLC that keeps
the entire system safe even when there are problems
with the external power supply or the PLC module.
Otherwise, trouble could result from erroneous output
or erroneous operation.
(1) Outside the PLC, construct mechanical damage
preventing interlock circuits such as emergency stop,
protective circuits, positioning upper and lower limits
switches and interlocking forward/reverse operations.
(2) When the PLC detects the following problems, it will stop
calculation and turn off all output in the case of (a).
In the case of (b), it will stop calculation and hold or turn
off all output according to the parameter setting.
Note that the AnS series module will turn off the output in
either of cases (a) and (b).
(a) The power supply module has over current protection
equipment and over voltage protection equipment.
(b) The CPU module self-diagnostic functions, such as the
watch dog timer error, detect problems.
In addition, all output will be turned on when there are
problems that the CPU module cannot detect, such as
in the I/O controller. Build a fail safe circuit exterior to
the PLC that will make sure the equipment operates
safely at such times.
(3) Output could be left on or off when there is trouble in the
outputs module relay or transistor. So build an external
monitoring circuit that will monitor any single outputs that
could cause serious trouble.
z When overcurrent which exceeds the rating or caused
by short-circuited load flows in the output module for a
long time, it may cause smoke or fire. To prevent this,
configure an external safety circuit, such as fuse.
z Build a circuit that turns on the external power supply
when the PLC main module power is turned on. If the
external power supply is turned on first, it could result
in erroneous output or erroneous operation.
z When there are communication problems with the data
link, refer to the corresponding data link manual for the
operating status of each station. Not doing so could
result in erroneous output or erroneous operation.
operating status of each station. Not doing so could
result in erroneous output or erroneous operation.

DANGER

CAUTION

z When connecting a peripheral device to the CPU
module or connecting a personal computer or the like to
the special function module to exercise control (data
change) on the running PLC, configure up an interlock
circuit in the sequence program to ensure that the
whole system will always operate safely.
Also before exercising other control (program change,
operating status change (status control)) on the running
PLC, read the manual carefully and fully confirm safety.
Especially for the above control on the remote PLC
from an external device, an immediate action may not
be taken for PLC trouble due to a data communication
fault. In addition to configuring up the interlock circuit in
the sequence program, corrective and other actions to
be taken as a system for the occurrence of a data
communication fault should be predetermined between
the external device and CPU module.
z Do not bunch the control wires or communication
cables with the main circuit or power wires, or install
them close to each other. They should be installed 100
mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause
erroneous operation.
z When controlling items like lamp load, heater or
solenoid valve using an output module, large current
(approximately ten times greater than that present in
normal circumstances) may flow when the output is
turned OFF to ON. Take measures such as replacing
the module with one having sufficient rated current.

When the PLC power supply is switched ON to OFF, proper output of the
control target may not be provided temporarily due to differences in delay time
and starting time between the PLC power supply and the external power supply
for control target (especially DC).
For example, if the external power supply for control target is switched on in a
DC output module and the PLC power supply is then switched on, the DC
output module may provide false output instantaneously at power-on of the
PLC. Therefore, it is necessary to make up a circuit that can switch on the PLC
power supply first.
Also, an abnormal operation may be performed if an external power supply fault
or PLC failure takes place.
To prevent any of these abnormal operations from leading to the abnormal
operation of the whole system and in a fail-safe viewpoint, areas which can
result in machine breakdown and accidents due to abnormal operations (e.g.
emergency stop, protective and interlock circuits) should be constructed outside
the PLC. The following page gives examples of system designing in the above
viewpoint.

5) Turn ON the start switch.
6) When the magnetic contactor (MC) comes on, the output equipment is powered and may be driven

(3) Fail-safe measures against failure of the PLC
Failure of a CPU module or memory can be detected by the self-diagnosis
function. However, failure of I/O control area may not be detected by the
CPU module.
In such cases, all I/O points turn ON or OFF depending on a condition of
problem, and normal operating conditions and operating safety cannot
sometimes be maintained.
Though Mitsubishi PLCs are manufactured under strict quality control,
they may cause failure or abnormal operations due to unspecific reasons.
To prevent the abnormal operation of the whole system, machine
breakdown, and accidents, fail-safe circuitry against failure of the PLC
must be constructed outside the PLC.

4.3 Power Supply Wiring
This section provides instructions for wiring the power supply.

DANGER

CAUTION

z Completely turn off the external power supply when
installing or placing wiring. Not completely turning off
all power could result in electric shock or damage to
the product.
z When turning on the power supply or operating the
module after installation or wiring work, be sure that
the module's terminal covers are correctly attached.
Not attaching the terminal cover could result in electric
shock.
z Be sure to ground the FG terminals and LG terminals
to the protective ground conductor. Not doing so could
result in electric shock or erroneous operation.
z When wiring in the PLC, be sure that it is done
correctly by checking the product's rated voltage and
the terminal layout. Connecting a power supply that is
different from the rating or incorrectly wiring the
product could result in fire or damage.
z External connections shall be crimped or pressure
welded with the specified tools, or correctly soldered.
Imperfect connections could result in short circuit,
fires, or erroneous operation.
z Tighten the terminal screws with the specified torque.
If the terminal screws are loose, it could result in short
circuits, fire, or erroneous operation. Tightening the
terminal screws too far may cause damages to the
screws and/or the module, resulting in fallout, short
circuits, or malfunction.
z Be sure there are no foreign substances such as
sawdust or wiring debris inside the module. Such
debris could cause fires, damage, or erroneous
operation.
z The module has an ingress prevention label on its top
to prevent foreign matter, such as wire offcuts, from
entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this
label because of heat dissipation.

(1) Separate the PLC's power supply line from the lines for I/O devices and
power devices as shown below.

(3) 100VAC, 200VAC and 24VDC wires should be twisted as dense as
possible. Connect the modules with the shortest distance.
Also, to reduce the voltage drop to the minimum, use the thickest wires
possible (maximum 2mm2).
(4) Do not bundle the 100VAC and 24VDC wires with, or run them close to,
the main circuit (high voltage, large current) and I/O signal lines. If
possible, run them more than 100mm (3.94 inch) away.

(1) Use the thickest possible (max. 2 mm (14 AWG)) wires for the 100/200
VAC and 24 VDC power cables. Be sure to twist these wires starting at
the connection terminals. To prevent a short-circuit should any screws
loosen, use solderless terminals with insulation sleeves.
(2) When the LG terminals and FG terminals are connected, be sure to
ground the wires. Do not connect the LG terminals and FG terminals to
anything other than ground. If LG terminals and FG terminals are
connected without grounding the wires, the PLC may be susceptible to
noise. In addition, since the LG terminals have potential, the operator may
receive an electric shock when touching metal parts.
(3) *1 Error output through the ERR terminal of the power supply module on
the extension base is not available. For error output, use the ERR
terminal of the power supply module on the main base.
4.3.1 Precaution when connecting the uninterruptive power supply
Be sure of the following terms when connecting the QCPU system to the
uninterruptive power supply (abbreviated as UPS hereafter):
Use a UPS which employs the constant inverter power supply method with 5 %
or less voltage fluctuation.
Do not use a UPS with the constant commercial power supply method.

4.4.2 Switch operation after writing program
Program can be written to the CPU module during STOP or RUN.
(1) When you write a program during STOP of the CPU module
When you write a program during STOP of the CPU module, operate the
switch in the following procedure.
1) RUN/STOP/RESET switch: STOP
RUN LED: OFF
CPU module STOP status to Program write
2) RUN/STOP/RESET switch: Perform reset. (Refer to Section 4.4.3)
3) RUN/STOP/RESET switch: STOP to RUN
RUN LED: ON
CPU module RUN status
(2) When you write a program during RUN
When you write a program during RUN of the CPU module, you need not
operate the switch.
POINT
(1) The CPU module will not go into the RUN status if you move the
RUN/STOP/RESET switch to RUN immediately after writing a program in
the STOP status of the CPU module. After writing a program, perform
reset operation with the RUN/STOP/RESET switch, then move the
RUN/STOP/RESET switch to RUN to set the CPU module into the RUN
status.
(Refer to Section 4.4.3 for reset operation.)
(2) To place the CPU module in the RUN status without resetting, move the
RUN/STOP/RESET switch from STOP to RUN to STOP to RUN.
After the second motion of STOP to RUN, the CPU module goes into the
RUN status.
(3) The program written by online program correction during boot operation is
written to the program memory
After making online program correction, also write the program to the
standard ROM of the boot source memory. If you forget to write the
program to the standard ROM, the old program will be executed at the
next boot operation.
(For details of boot operation, refer to the Basic Model QCPU (Q Mode)
User's Manual (Function Explanation, Program Fundamentals).)

4.4.3 Reset operation
For the Q00J/Q00/Q01CPU, the RUN/STOP/RESET switch of the CPU module
is used to switch between the "RUN status" and "STOP status" and to perform
"RESET operation".
When using the RUN/STOP/RESET switch to reset the CPU module, moving
the RUN/STOP/RESET switch to the reset position will not reset it immediately.
POINT
Hold the RUN/STOP/RESET switch in the RESET position until reset
processing is complete (the flickering ERR. LED goes off).
If you release your hand from the RUN/STOP/RESET switch during reset
processing (while the ERR. LED is flickering), the switch will return to the
STOP position and reset processing cannot be completed.
Perform reset operation with the RUN/STOP/RESET switch in the following
procedure.

5.5 Wiring of I/O Equipment
(1) The wires used for connection to the terminal block should be 0.3 to
2
0.75mm in core and 2.8mm (0.11 inch) max. in outside diameter.
(2) Insulation-sleeved crimping terminals cannot be used with the terminal
block.
It is recommended to cover the wire connections of the crimping terminals
with mark or insulation tubes.
(3) Run the input and output lines away from each other.
(4) When the wiring cannot be run away from the main circuit and power
lines, use a batch-shielded cable and ground it on the PLC side.
In some cases, ground it in the opposite side.
PLC

Shielded cable

Input
Output

Shield

(5) Where wiring runs through piping, ground the piping without fail.
(6) Run the 24VDC input line away from the 100VAC and 200VAC lines.
(7) Wiring of 200m (686.67 ft.) or longer distance will give rise to leakage
currents due to the line capacity, resulting in a fault.
Refer to the troubleshooting chapter of the I/O Module User’s Manual.

6. Error Codes
If a fault occurs when the CPU module is switched from STOP to RUN or during
running (while the PLC system is ON), the CPU module will output the error
(LED indication) by the self-diagnosis function and store the error information in
the special relay (SM) and special register (SD).
REMARK
For the error code (4000H to 4FFFH) of the errors occurred on GX Developer,
intelligent function module or network system at request for general data
processing, refer to the user’s manual of the CPU module (Hardware Design,
Maintenance and Inspection).
6.1 How to Read the Error Code
If an error occurs, read the error code, error message and so on using the
following GX Developer.
CPU Module
Q00JCPU, Q00CPU, Q01CPU
Q02 (H) CPU, Q06HCPU, Q12HCPU, Q25HCPU
Q12PHCPU, Q25PHCPU

GX Developer
Version 7 or later
Version 5 or later
Version 7.10L or later

Use the following procedure to read the error code with GX Developer.
(1) Start GX Developer.
(2) Connect the PLC and peripheral device.
(3) On GX Developer, choose the [Online]-[Transfer setup] menu and specify
the port and the CPU module from which the error code will be read.
(4) Choose [Diagnostics]-[PLC diagnostics] menu.
(5) Clicking the Current error button in the PLC diagnostics dialog box
shows the error code and error message.
(6) Choose the [Help]-[PLC error] menu and confirm the definition of the
corresponding error code.
For details of how to operate GX Developer, refer to the operating manual of
your GX Developer.
