do apply in your country.
Proposition 65 Warning (US Only)
State of California Proposition 65 Warning (US only)
WARNING: This product contains chemicals known to the State of California to
cause cancer and birth defects or other reproductive harm.
Electrical
The product is designed to operate from a -48 V DC supply and is therefore
classified as Safe Extra Low Voltage (SELV) equipment.
All structural parts are grounded and all input and outputs have built-in isolation
from the network. All input and output ports that connect to external power
sources are designed to meet relevant national safety requirements.
The product contains hazardous energy levels as defined by EN 60950. Care must
be taken when maintaining this equipment as injury to personnel or damage to the
equipment could result from mistakes. Maintenance should only be carried out by
trained and competent engineers who are familiar with the relevant procedures and
instructions.
Lasers
The product is fitted with optic modules rated as Class 1 radiation-emitting devices
under EN 60825-1. During installation, operation, and maintenance, never look
into the end of an optical fiber directly or by reflection either with the naked eye or
through an optical instrument. Do not operate equipment with exposed fiber
connectors-cover these with fiber cables or blanking caps. Do not remove
equipment covers during operation unless requested to do so in the documentation.
Carry out normal safety precautions when trimming fibers during installation.
Manual Handling
Care should be taken when handling equipment. Give due consideration to the
weight of the equipment, the physical capability of the individual(s) handling the
equipment, and movements such as twisting, bending and stooping, which could
lead to skeletal and muscular injuries.
Installation
Installation must be carried out by trained and competent engineers only. All
relevant safety measures should be taken to ensure equipment is not connected to

Preface
live power and transmission sources during installation. Equipment must be
correctly installed in order to meet the relevant safety standards and approval
conditions.
Each power feed to the unit requires a separate fused feed from the provided
power supply. The cable between the power distribution point and the installed
equipment must have a minimum cross-sectional area of 2.5 mm2.
Rack-mountable equipment must be placed in a standard 19-inch rack and secured
with the appropriate fixings as detailed in the installation manual.
Maintenance
Maintenance must only be carried out by a suitably trained and competent
technician. All safety instructions must be carefully observed at all times.
Equipment covers should not be removed while live power and transmission is
connected unless in a controlled environment by trained technicians.
Fire
The product is powered from a -48 V DC supply. To protect against fire, the
equipment is fused.
Environment
The product must be operated in an environment with the specified relative
humidity and ambient temperature ranges.
Keep all liquids away from the equipment as accidental spillage can cause severe
damage.
Cooling
The product cools down by its own set of cooling fans housed in a fan module.
Each fan module detects a fan that is not operating normally. LEDs on the front
panel of the fan module provide an alarm indication in the event of fan failure.
In the event of fan failure, take urgent remedial action to restore full cooling
capacity.
Take appropriate measures to ensure that fan modules do not start spinning during
repair and maintenance procedures.
Anti-Static Precautions
The circuit boards and other modules in the product are sensitive to and easily
damaged by static electricity. If any card or sub-assembly is removed from the unit,
the following anti-static precautions must be observed at all times:

Service personnel must wear anti-static wrist straps.

Circuit boards and sub-assemblies must be placed on ground conductive mats

Preface
or in conductive bags.

All tools must be discharged to ground before use.

The anti-static wrist strap and cord must be checked at regular intervals for
their suitability for use.
Grounding
To comply with EN 60950, the equipment must be connected to a safety
grounding point via a permanent link. Grounding points are located on the product
for this purpose. Always connect the ground cable before fitting other cables. The
product must remain grounded continuously unless all connections to the power
supply and data network are all removed.
If equipment is grounded through a cabinet or rack, make sure it is done so
properly according to the installation instructions.
Power Supply Connection
The equipment is designed to be powered from a -48 V DC supply. Power
connections and installation of associated wiring must be carried out by a suitably
qualified technician.
Only devices that comply with all relevant national safety requirements should be
connected to the unit’s power supply inlets. Other usage will invalidate any
approval given to this equipment.
Connection of this equipment to devices that are not marked with all relevant
national safety requirements may produce hazardous conditions on the network.
When the power supply is obtained by a rectifier/safety isolation transformer, the
supply must meet the requirements of EN 60950 providing double/reinforced
insulation between hazardous voltages and SELV/TNV circuits. Any battery must
be separated from hazardous voltages by reinforced insulation.
Indirect Connection
Before indirectly connecting any equipment to another device through a shared
power supply, ALWAYS seek advice from a competent engineer.
Devices that are not marked according to the relevant national safety standards
may produce hazardous conditions on the network.

Installing the system with power switch on may cause system damage or fatal
human injury when cables are not correctly connected.
Make sure that worker wears protection gloves and goggles to prevent damage
from debris while drilling holes in a wall or ceiling.
Do not wear accessories such as watches and rings in order to prevent electrical
shock.
Never allow foreign substances to be inserted into unused ports by covering them
with a cap.
To prevent foreign substances, outdoor air and moisture from entering the cable
inlet (including cable gland and conduit), finish it as follows:
- Unused inlet
Use the hole finishing materials including cap and rubber packing.
- Cable-installed inlet
After cable installation, block any space in the inlet with tape, compressed sponge,
rubber packing, and silicon.

While moving system, the system should not be shocked physically and
damaged caused by dust, moisture, and static electricity.
Unpacking Items
The procedure to unpack items is as follows:

The packing items must be packed until they reach the installation place.

The items are classified in accordance with each job specification and stored
on a place that does not interfere with working.

Unpacked systems must be installed immediately. If not installed immediately,
the systems must be stored in the installation place temporarily.

Unpack only external packing, leaving the internal packing in unpacked status.

Unpack the inner packaging after each system is placed on its installation
location.

Scrap by-products (packaging waste) in accordance with the rule. Do not
recycle the by-products.

The procedure for cable connections is as follows:
Figure 48. Cable Connection Procedure
Cable Path Inspection
Cable Cutting
Cable Installation
Connector Attachment
When assembling the
connector at the site
Connector Assembly
Cable Binding
Identification Tag Attachment
When cutting the cable after installation, make sure that the connector is
disconnected. Installation of the cable with the connector connected to the system
may cause contact failure or damage to the connector assembled to the system and
the cable due to cable tension or the operator’s mistakes.
The sequence of cable cutting and installation of the cable workflow can be
changed depending on the field situation such as ‘cutting after installing’ or
‘installing after cutting’.
Cable Path Inspection
When installing a cable that connects between the rectifier, Main Ground Bar
(MGB), and backhaul device, and so on within the system, the cable path, length
and the cable installation method, and so on must be inspected.
Follow these guidelines when inspecting the cabling path.

A minimum cable length must be selected provided that it does not affect the
cable installation and maintenance.
RFD01P Series Installation Manual v1.0
Copyright © 2017, All Rights Reserved.
lvi
Chapter 3 Connecting Cables

The cable must be placed in a location where it will not be damaged by
external factors (power line, flooding, footpaths, and so on).

In areas where the cable may be damaged by external factors, ensure that
measures are taken to prevent damage to the cable (cable tray, ducts, flexible
pipe, and so on).
Cable Cutting
Measure the exact distance, carefully checking the route, and cut the cable using a
cutting tool.
Follow these guidelines when cutting the cable.

Cut the cable to the length determined in the Cable Path Inspection step.

Use a dedicated cable cutting tool.

Cut the cable at right angles.

Be careful to keep the cable away from any moisture, iron, lead, dust, or other
foreign material when cutting.

Remove any foreign material attached to the cable using solvent and a brush.
Cable Installation
Cable installation involves running the cable along the cabling path to the target
connector of the system or an auxiliary device after cable path inspection and cable
cutting have been completed.
Follow these guidelines when installing a cable:

Be careful not to damage the cable.

If the cable is damaged, cut out the damaged section before installing, or
replace the cable.

Run the cable so that it is not tangled. In particular, when installing a cable
from a horizontal section to a vertical section, be careful not to reverse the
upper and lower lines of the cable.

Always use the maximum curvature radius possible, and make sure that the
minimum curvature radius specification is complied with.

If the cable needs to be protected, use for example, a PVC channel, spiral
sleeve, flexible pipe, cable rack, and so on.

Install the DC power cable and data transmission cable away from the AC
power cable to prevent electromagnetic induction.

※ If the allowed cable bend radius is specified by the manufacturer, comply with the bend radius specified.
Cable Binding
Cable binding involves fixing and arranging an installed cable using binding
thread, cable ties, binding wire, and ram clamps, and so on.
Follow these guidelines when binding a cable.

Be careful not to damage the cable during binding.

Use appropriate cable binding tools according to the target location (indoor or
outdoor, and so on) and the type of the cable (power supply cable, optical
cable, feeder line, and so on).

Do not let the cutting section of a cable tie and binding line, and so on be
exposed to the outside. This may cause damage to cables or personal injury.
Make sure that the cutting sections of cable ties and binding lines, and so on
are not exposed to the outside.

Cut off the remainder of the cable thread by leaving about 50 mm of extra
length to prevent the knot from easily getting untied.

If there is a danger that contact failure may occur in a connector connection
due to tension, bind the cable at the closest location to the connector.
Connector Attachment
Connector attachment involves assembling a connector to an installed cable or to a
device on the site.
Follow these guidelines when attaching a connector.

Make sure operator is fully aware of the connector assembly method before
assembling a connector. Assemble the connector in accordance with its pin
map.

Each connector has a hook to prevent its core positions from being changed.

Check the corresponding grooves before connecting a connector to another
RFD01P Series Installation Manual v1.0

Chapter 3 Connecting Cables
connector.

Use a heat shrink tube at a connector connection for cables that are installed
outdoor, such as feeder lines, to prevent water leakage and corrosion from
occurring at the part exposed to the outside.

Connect each cable of the connector assembly in a straight line.

Be careful when connecting a cable so that contact failure does not occur at a
connector connection due to tension.
Identification Tag Attachment
Identification tag attachment involves attaching a marker cable tie, nameplate, and
label, and so on to the both ends of a cable (connections to a connector) to identify
its use and cabling path.
Follow these guidelines when attaching an identification tag.

When installing a cable outdoor, use relief engraving and coated labels, and so
on to prevent the markings from being erased.

Since the form and attachment method for identification tags are different for
each provider, consult with the provider before attaching them.
When connecting the cables, always connect the ground cable first. If worker
contacts the equipment, connect a cable or perform maintenance without
connecting the ground cable, the system can be damaged or a worker may be
injured due to static electricity and short circuit.
When performing cable work for the system, proceed with the ground work before
any other work to prevent errors occurring due to static electricity and other
reasons.
After completing cable installation, unused port should be capped.
When installing, take care not to overlap or tangle the cables; also, consider future
expansion. Install the DC power cable and data transmission cable away from the
AC power cable to prevent electromagnetic induction.
Make sure the work is done by personnel properly trained for the cabling job.

Grounding
Grounding is the process of operating an electronic system (for example. power
supplying system, communication system, and control system) stably from a
lightning, transient-current, transient-voltage and electric noise and of preventing
injury from electric shock.
Ground equipment minimizes the electrical potential of the electronic device to
that of the ground, which is zero electrical potential, so that it can prevent the
device from occurring electrification.
Connect the ground cable first. In cabling, the connection of cables without the
connection to the ground cable may cause damage of the equipment or bodily
injury to personnel.
The purposes of the ground construction are as follows:

To prevent human life and the system from over-current, over-voltage, and
lightning

To provide a discharge path for surge voltage generated by lightning and
power switch

To protect the system from static electricity

To eliminate or minimize the high-frequency potential in the system housing

To provide a conductor for the balance and stability of high-frequency current

To stabilize the potential of the circuit against the ground

The power supply device consists of the following elements:

DC
Rectifier
System
Since power is applied to the system where the power cable is connected by
manipulating the circuit breaker of the rectifier, be sure to check the rectifier’s
breaker is turned off (open) before connecting the power cable to the power
connector. If the system is installed while the circuit breaker is on, the worker may
be critically injured as soon as the cable is connected in the wrong way.
Handling the power cable incorrectly may damage the rack or cause an electric
short-circuit through the cable. Ensure the power switch on the rectifier or the
system is turned off before handling the power.
The fasteners for power cable must be tightly secured to prevent electrical
accidents.
The heat-resistant temperature of the power cable should be 90°C or more.
Install the power cable to the power port of the system by considering the radius of
curvature of its cable specification and then cut the cable. If operator installs the
cable after cutting, there may be length difference among the core wires at the end
of the cable because of cable curvature. This may result in poor contact after the
cable is connected to the power port.
When using the system DC power cable, the length of the power cable can be up to
30m with AWG 10 specification, and is available up to 40 m with AWG 8
specification. The separation distance is decided only by normal installation. The
maximum separation distance may change when conditions changes.
Install a circuit breaker to a rectifier (or power distributor) for the stable power.
The capacity of circuit breaker is 20A or 25A. (Use UL Listed circuit breakers.)

Checking RF Cable Connection
After connecting the RF cables, perform the continuity test and feeder cable return
loss to check if the RF cable is changed and measure VSWR of antenna and RF
cable.
Connection Part of System External Interface Connector
①
②
Antenna
Measure all cables of section ①~②. The measured VSWR should be the
specification value or less. If the VSWR exceeds the specification value,
disassemble the connector and measure each section separately.
If the VSWR value for minimum cable bend radius and length of RF cable is not
applied, system may not work properly because RF signals cannot transmit or
receive smoothly. So, the VSWR value for minimum cable bend radius and length
of RF cable must be checked and applied.
When measuring VSWR, if operator opens the antenna port when the transmission
output is not completely off, a spike signal may flow into the reception path, which
may cause damage to LNA. Make sure the transmission output is completely off
when measuring VSWR.
When RF cable connection integrated RET signal and DC power is applied using
ANT1 port of RRU, RET cable should be installed separated from RF cable to RF
Antenna.
Depending on the supplier or manufacturer of antenna/arrestor the connector type
may be different. Also, the detail specifications of a connector may be different
depending on cable type even for the same connector type. Therefore, check the
detail specifications of a connector before preparing parts.

inspection checklist actually at a site where the system is installed.
The inspector must record the results onto the inspection checklist during or after
filed inspection.
Sharing Inspection Results and Taking Corrective Actions
The inspector must share the inspection results (inspection checklist/corrective
actions) with an installation operator and, the installation operator must take the
corrective actions if necessary after reviewing the requirements.
Checking the Results of Corrective Actions
The inspector must check if the corrective actions are properly taken. If they are
not sufficient, the inspector must ask the installation operator to take the corrective
actions again.
Sharing the Results of Corrective Actions and Preparing Preventive Plan
After the corrective actions are all completed, the inspector must share the results
with the installation operator and relevant departments and prepare a preventive
plan to prevent the same or similar problems from re-occurring.
