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.

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.

Cautions for Installation
Observe the safety instructions described in this section when installing the
system. Installation must be done in accordance with the applicable local electric
codes.
Before Installing

Post warning signs in areas where high-voltage cables are installed.

Post ‘off limit’ signs in areas where accidents are most expected.

Use guardrails or fences to block open areas such as ditches, open roof areas,
and scaffolds.
Install the system in the restricted access area.
While Installing
The system power must be cut off before installing.
Ensure the power switch of power supply is off when installing the system.
Installing the system with power switch on may cause system damage or fatal
human injury when connecting or disconnecting cables.
Ensure that workers wear protection gloves and goggles to prevent injury from
debris while drilling holes in a wall or ceiling.
Do not wear accessories such as watches and rings to prevent electrical shock.
Cover unused ports with a cap. This prevents foreign substances from entering into
the unused ports.
To prevent foreign substances, outdoor air, and moisture from entering the cable
inlet (including cable gland and conduit), finish the inlet 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 silicone.
Keep a safe distance between the base station antenna and people.

Do not co-locate nor operate in conjunction with any other antenna or transmitter
for the protection of general public from exposure to radio frequency
electromagnetic field.
After Installing
Remove any debris produced during the work and clean up the installation site.
In the system, the laser beam light runs through the optical cable. The workers
must handle the optical cables with care as the laser beam can seriously damage
the eyes.
Ensure that the workers do not damage installed cables while cleaning the system.
While cleaning the power supply device, take precaution that the device does not
come in contact with foreign objects that may cause power failure.

Take care of the following at each stage of transportation of the items:

Before moving a system, check storage place for the system and remove
obstacles in advance.

When carrying the system:

Fasten the system firmly to the transport vehicle or carrier to prevent damage
to the system from a vibration or shock.

Use an elevator to prevent accidents. However, if the system must be carried
by people, ensure there are enough people to carry the system.

The system must not be shocked physically.

Care must be taken to protect the system from dust, moisture, and static
electricity.
Unpacking Items
To unpack the items, ensure the following:

The items must be packed until they reach the installation place.

The items are classified in accordance with each job specification and stored at
a place that does not interfere with working.

Unpacked systems must be installed immediately. If immediate installation of
the systems is not planned, the systems must be stored in the installation place
temporarily.

Unpack only external packing, leaving the internal packing in unpacked status.

Working Tools
 Tape Measure
 Permanent Maker
 Level
Perform leveling test before drilling by referring to System Leveling, to ensure the
positions marked are horizontal or vertical. If the result shows the marked
positions are not horizontal or vertical, modify the marking positions.
When the position to place the system is determined, place the system on that
position and then mark the positions where anchor bolts are to be fixed. This
reduces marking error range.

When cutting the cable after installation, ensure that the connector is disconnected.
The cable installation while the connector is connected to the system may cause
contact failure, or damage to the assembled connector and the cable, due to cable
tension or operator 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 interconnects rectifier, Main Ground Bar (MGB), and
backhaul device, within the system, cable path, length, and cable installation
method must be inspected.
To inspect the cable path, ensure the following.

A minimum cable length must be selected, so that the length does not affect
the cable installation and maintenance.
5G AU Installation Manual v2.0
Copyright © 2017, All Rights Reserved.

Chapter 3 Connecting Cables

The cable must be placed in a location where the cable is not damaged by
external factors such as power line, flooding, and footpaths.

In areas where the cable may be damaged by external factors, ensure that
measures are taken to prevent damage to the cable, such as cable tray, ducts,
and flexible pipe.
Cable Cutting
Measure the exact distance after carefully checking the route, and cut the cable
using a cutting tool.
To cut the cable, follow these guidelines:

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 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
This process involves running the cable along the cabling path to the target
connector of the system or an auxiliary device. This is done after cable path
inspection and cable cutting are completed.
To install the cable, follow these guidelines:

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 the 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 ensure that the
minimum curvature radius specification is complied with.

If the cable needs to be protected, use suitable protective cover such as PVC
channel, spiral sleeve, flexible pipe, and cable rack.

Install the DC power cable and the 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
This process involves fixing and arranging an installed cable using binding thread,
cable ties, binding wire, and ram clamps.
Follow these guidelines when binding a cable.

Be careful not to damage the cable during binding.

Use proper cable binding tools according to the target location (indoor or
outdoor) and the type of the cable (power supply cable, optical cable, or feeder
line).

Ensure the cutting sections of the cable tie and the binding line are not exposed
to the outside. This may cause damage to the cables or personal injury.

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 chance of contact-failure to occur in the connector connection due
to tension, bind the cable at the closest location to the connector.
Connector Attachment
This process involves assembling a connector to an installed cable or to a device
on the site.
Follow these guidelines when attaching the connector.

Ensure operator is fully aware of the connector assembly method before
assembling the 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 the connector to another
connector.

Use a heat shrink tube at the connector connection for cables that are installed
5G AU Installation Manual v2.0

Confidential
Chapter 3 Connecting Cables
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 the cable so that contact failure does not occur at
the connector connection due to tension.
Identification Tag Attachment
This process involves attaching a marker cable tie, a nameplate, and a label to both
ends of a cable (connections to a connector) to identify the use of the cable and the
cabling path.
Follow these guidelines when attaching an identification tag.

When installing the cable outdoor, use relief engraving and coated labels 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 the tags.
When connecting the cables, always connect the ground cable first. If a worker
contacts the equipment, connects a cable, or performs maintenance without
connecting the ground cable, the system can be damaged or the 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 ports must be capped.
When installing, take care not to overlap or tangle the cables. In addition, consider
future expansion. Install DC power cable and data transmission cable away from
AC power cable to prevent electromagnetic induction.
Ensure the work is done by personnel properly trained for the cabling job.

Chapter 3 Connecting Cables
Grounding
Grounding is the process of operating an electronic system such as power supply
system, communication system, and control system, stably without damage from
lightning, transient-current, transient-voltage, and electric noise. Grounding also
helps in 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. This prevents electrification
of the electronic device.
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

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
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
get critically injured if 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 of 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.
If you turn the power on and off rapidly (within 1 s), the counter electromotive
force caused by cable inductance can damage the system.
Connecting more than one power cable together may increase power loss.
It must be verified that the rectifier or the power distributor has an output voltage
within the specified system input range before the power line is connected.

The on-site inspection is to perform inspection visually or using instruments for
each specification, standard, and installation status, based on the inspection
checklist at the site where the system is installed.
The inspector must record the results onto the inspection checklist during or after
field inspection.
Sharing Inspection Results and Taking Corrective Actions
The inspector must share the inspection results (inspection checklist and corrective
actions) with an installation operator. 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. The inspector must prepare
a preventive plan to prevent the same or similar problems from re-occurring.
