Preface
Personal and Product Safety
This product safety information includes European directives, which you must
follow. If these do not apply in your country, please follow similar directives that
do apply in your country.
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 UL 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.
Confidential
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
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.

Page 13
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. 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.
Confidential
Preface
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
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 UL 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.
Power Supply Connection
Power connections and installation of associated wiring must be carried out by a
suitably qualified technician.

Preface
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 UL 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 should be done in accordance with the applicable local electric codes.
Before Installing
Before starting the installation, ensure the following:
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.
Confidential
Chapter 1 Before Installation
When installing RRH, especially when installing as sector, it must be installed that
EIRP is not exceed max 21 dBm at > 30 degree above horizon for outdoor.
While Installing
During installation, ensure the following:
The system power must be cut off before installing.
Ensure that the power switch of the power supply is off when installing the system.
Installing the system with power 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.
When using the AC / DC converter, connect the DC power cable first before
connecting the AC power.
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.
RT2201-46A Installation Manual v2.0 7

Page 24
Chapter 1 Before Installation
- Cable-installed inlet: After cable installation, block any space in the inlet with
tape, compressed sponge, rubber packing, and silicone.
After Installing
After installation, 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.
When using the AC / DC converter, if servicing of the RRU is required, disconnect
the AC power first.
Confidential
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.

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 the cable that interconnects rectifier, Main Ground Bar (MGB),
backhaul device, and so on within the system, the 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.

measures are taken to prevent damage to the cable, such as cable tray, ducts,
and flexible pipe.
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.

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.
Confidential
Chapter 3 Connecting Cables
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 weather proof tape at the 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.

Chapter 3 Connecting Cables
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.
Confidential
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, ensure not to overlap or tangle the cables. In addition, consider
future expansion. Install the DC power cable and the data transmission cable away
from the AC power cable to prevent electromagnetic induction.
Ensure that the work is done by personnel properly trained for the cabling job.
