SAFETY CONCERNS
Warning
WARNING
Power and Grounding
Watches, Rings, and Other Metallic Accessories
Do not wear accessories such as watches and rings in order to prevent electrical
shock.
Power Switch Off
Make sure the power switch of power supplier is off when installing the system.
Installing the system with power switch on may cause system damage or fatal
human injury when cables are not correctly connected.
Warning for Connecting the Ground Cable
In cabling, the connection of cables without the connection to the ground cable
may cause the damage of the equipment or the injury of the worker.
Connect the ground cable first.
Installation
Warning for Laser Beam Running through Optical Cables
In the system, the laser beam emitting light runs through the optical cable.
The exposure of the laser beam on worker’s eye may cause serious injury so that
it should be handled with care.
Protection gloves and goggles
Make sure that worker wears protection gloves and goggles to prevent damages
from debris while drilling holes in a wall or ceiling.

Caution
CAUTION
Power and Feeder line
Cautions while Cleaning Power Supply
While cleaning the power supply device, take caution that the device does not
come in contact with alien bodies that may cause power failure.
Handling the Power Cable
- Handling the power cable incorrectly may damage the rack or cause an electric
shock through the cable. Ensure the power switch on the rectifier or the system
is turned off before handling the power cable.
- The fixing materials for power cable must be tightly secured to prevent electrical
accidents.
Power cable
In case of using AWG8 (6 mm2 × 2C) power cable, it is applicable up to 70 m
(299.66 ft). When the distance is 70 m (299.66 ft), followings should be considered.
- Do not rapid ON/OFF (within one second): The voltage loss value caused by the
cable resistance loss is 3 V, and the RRH-2WB could be damaged by the
counter electromotive force caused by the cable inductance.
- The battery’s life could be shorten: The RRH-2WB could be off in spite the
battery remains. (When the battery capacity is designed within one hour)
- Do not use the power cables linked: Using the power cables linked each other,
the loss will be increased.
Precautions for Measuring Insulation Resistance
Since a high voltage is used for measuring insulation resistance, insulation
resistance should not be measured when the system is in operation. Make sure to
only measure the insulation resistance of the appointed part. Other components
such as the system’s internal components and the unit (system frame),
components of the communication cables, units, etc. should not be measured.
Cable Work Sequence
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.

SAFETY CONCERNS
Connection of Feeder Cable Connector
Connecting the feeder cable connector is critical process, so the qualified workers
who finished the related education should perform.
Radius of Curvature of Feeder Line
When installing a feeder line, the radius of curvature of the sections where cables
bent should be larger than the allowed radius of curvature. If the radius of
curvature for the feeder line installation is less than the allowed radius of curvature,
it may affect the performance of the system.
Installation
Cautions while Cleaning the Rack
Make sure that worker does not damage installed cables while cleaning the rack.
System Installation and Access
Only authorized workers are allowed to install or access the system.
Do not Work by Yourself
Worker must not work alone in any key process.
Management of Unused Ports
Cover the unused ports (conduit, cable gland, etc.) with waterproof cap (sealing
cap) to prevent infiltration of foreign material such as dust, moisture, or bug.
Caution When Connecting the Optical Cable
When connecting the optical cable, be careful to keep the cutting section of the
connector core away from dust and foreign substances. If the cable is soiled with
foreign substances, do not blow on the cable to remove them. Make sure to
remove the dust or foreign substances in accordance with the cleaning
instructions provided by the connector manufacturer.

Finishing Heat Shrink Tube of a Sector Antenna
1) Insert an antenna protection plate to antenna port.
2)
Place the heat shrink tube on the connection point and shrink the heat shrink
tube using a heat gun. Avoid aiming the heating gun toward the antenna’s body.
Installing the Antenna
When you install the antenna, the distant and angle between the antenna and
lightning rod must be within the protective angle (left/right side 45° each from the
central axis) to prevent the antenna from lightning damage.

2.5 System Leveling
Leveling refers to compensating for the level difference on the floor that is generated
during floor work to install devices horizontally or vertically. Leveling can be carried out
using a vinyl hose, a balance weight, or a level.
However, levels are used for this system.
Leveling Using a Level
1) Attach a level to the top, left, and right of the system.
2) Adjust the system height so that the bubble in the level moves to the center of the
window. (In the case of a digital level, the LCD should indicate an even plane.)
3) Leveling is complete when the bubble stays at the window center in every level.
Leveling Test for Wall Type System (Before Fixing the Anchor Bolt)
1)
Before fixing the anchor bolts, draw a vertical and a horizontal between the markings of the anchor
bolts, as shown in the Figure below. Make the lines vertical/horizontal using a spirit level.
2)
When the lines are not placed in vertical/horizontal, complying with the distance to fix the equipment,
modify the markings of the anchor bolts until the lines are placed in vertical/horizontal.

2.6 Insulation Test
When conducting an insulation test, it is advised to set the insulation tester to DC 500 V
and the insulation value is recommend as 100 MΩ or higher.
1)
2)
3)
Connect a lead of an insulation tester to the Hex.bolt for fixing the RRH-2WB.
Connect another lead to the anchor bolt.
Measure the insulation resistance by using the insulation tester.
The insulation resistance should be over 100 MΩ.
If the measured resistance is less than 100 MΩ, the value indicates the insulation failure.
Thus, check the following and perform the insulation test again.

Check if the connection between the Hex.bolt for fixing the RRH-2WB and the anchor
bolt is proper. (Note that the anchor bolts must be shielded with an insulated bushing.)

Check if the insulated bushing is damaged.

Replace the insulator (insulated bushing, bakelite, rubber pad, etc.) or parts for fixing.

Figure 2.32 Schematic Diagram for Insulation Test
Precautions for Measuring Insulation Resistance
Since a high voltage is used for measuring insulation resistance, insulation
resistance should not be measured when the system is in operation. Make sure to
only measure the insulation resistance of the appointed part. Other components

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.
3-2

Be careful not to damage the cable.

If the cable is damaged, cut out the damaged section before installing.

When installing the cable over other cables, make sure the cable is installed on the
other cables. Pay more attention to the vertical and horizontal cross sections where the
cables are usually reversed.


3.3 Grounding
Grounding is required for protecting complex electronic or electric systems such as power
system, communication system, and control system from lightning, over-current, overvoltage, and electric noise. Thus, the systems can operate properly and protect human life
from electrical 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.

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
Connecting Ground Cable
In cabling, the connection of cables without the connection to the ground cable
may cause the damage of the equipment or the bodily injury of the worker.

Circuit Breaker Installation
Circuit breaker of slow blow type should be installed to the power line which is
connected from the rectifier (or power distributor) to the system in order to supply
the power stably. The capacity of -48 VDC circuit breaker is 20 A.
Power cable
In case of using AWG8 (6 mm2 × 2C) power cable, it is applicable up to 70 m
(299.66 ft). When the distance is 70 m (299.66 ft), followings should be
considered.
- Do not rapid ON/OFF (within one second): The voltage loss value caused by the
cable resistance loss is 3 V, and the RRH-2WB could be damaged by the
counter electromotive force caused by the cable inductance.
- The battery’s life could be shorten: The RRH-2WB could be off in spite the
battery remains. (When the battery capacity is designed within one hour)
- Do not use the power cables linked: Using the power cables linked each other,
the loss will be increased.

ANNEX A. Sector Antenna Installation
A.1 Cautions when Installing a Sector Antenna
Precautions of antenna installation are as follows.

Sector antennas should be installed vertically. (± 1°)

Antenna is the precise material, so be careful not to make damage or form change.

When moving antenna, use the tool suitable to rating. In addition, use the rated
carrying device which is at least 200 % or more than antenna considering the stability.

Be careful not to give too much strength to the antenna.

If it rains, suspend connecting the feeder cable and antenna.

Fix it after adjusting the direction of antenna exactly.

Distance between steel tower and antenna and the distance between send-receive
antennas are based on the antenna layout.

Attach the antenna on the position specified in the drawing.

Install the antenna not to make a feature change of the antenna considering the
direction of the radiation

Connect the antenna not making the alien substance flowed so that Passive InterModulation Distortion (PMID) is not affected.

Measure VSWR of all antennas and the value should be within the regulated value.
A.2 Sector Antenna Layout
The method of sector antenna layout is as follows.
1) Use the transit to adjust the antenna installation direction exactly.
2) Fix the direction of the sector antenna, same as the angle settled when designing the
cell after installing the steel tower.
3) Arrange the antennas of each sector to the sector directional angle at right angles by
adjusting the distance between antenna and steel tower.
In the event of the station whose the direction between sectors is not 120°, install it to
make the steel tower and antenna direction different being careful of the tilt and azimuth.
4) For circular platform, separate the antenna interval at maximum.

ANNEX A. Sector Antenna Installation
A.3 Sector Antenna Installation
The method of sector antenna installation is as follows.
1)
Put up an antenna pole and insert the sector antenna into the antenna pole using a
fixing clamp.
2) Set the antenna’s up/down tilt to 0° and fix the fixing clamps at the top and bottom.
3) After tightening the fixing clamp, adjust the antenna up/down (tilt) depending on the
signal strength. The bolt of the guide clamp must be loosened, so the antenna angle can
be adjusted.
4) After setting the antenna angle, tighten the bolt of the guide clamp, which was
loosened previously. Regarding the nut, the double nut mounting should be used to
prevent the nut from coming loose.
