WARNING
Power and Grounding
Cautions When Using Insulation Tester
Pay attention to the followings to prevent any personal injury caused by an
electric shock when using an insulation tester.
- Make sure the polarity is correct when connecting the Earth COM (black) and
AC.V (red) lead lines. And do not touch the connected probes (inspecting part of
the lead line) with a hand and avoid body contact.
- Avoid body contact to the system when measuring an insulation resistance.
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.
Connecting Ground Cable
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.
Turning Off the Circuit Breaker before Connecting the Power Cable
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.

SAFETY CONCERNS
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.
Precautions While Measuring Insulation Resistance
Observe the followings to prevent any system damage when measuring insulation
resistance because there is a very high voltage.
- Before measuring insulation resistance, disconnect all the cables connected to
the system.
- Do not measure insulation resistance when power is on.
- Do not measure insulation resistance at any other positions such as system
internal units or parts other than the targeted insulation resistance measuring
points.
System Grounding Method
Ground bar for lightning protector/power/communication must be isolated from
each other. These three ground bars can be grounded as the isolation grounding
method, or branched from ground mesh buried in the underground as common
grounding method.
Precautions When Connecting Power Cable
To secure rainproof performance of a cable gland, min. 11.81 in. (300 mm)
straight section must be maintained. Here, the radius of curvature must be
considered according to the cable specification.
When Using Power Cables
- When handling the power cable, ensure the power switch of a rectifier is turned
off to prevent the risk from the power cable and electric short-circuit of related
cables.
- Because a power accident may occur when fixing parts get loosened, make sure
that fasteners to fix the power cable should be firmly fastened.

Check When Fixing the Power Cable
Fix the power cable and the power cable bracket using a stainless steel tie for
preventing loose contact due to cable tension and leakage problems.
It is recommended to use the designated tools to tighten the stainless steel tie.
Caution for Rain-proof Gasket Damage
Be careful the rain-proof gasket is not damaged during work, and check again the
gasket is not damaged before closing power/DTA window cover. If the rain-proof
gasket is damaged, replace the RRH-B4.
Power Window Cover
Be sure to check the circuit breaker for RRH-B4 is turned off before opening or
closing the power window cover. If the cover is open or close while the circuit
breaker is on, the system can be damaged or a worker may be critically injured
due to electrical short-circuit.
Precautions When Cutting Power Cable
Install the power cable to the power port of system by considering the radius of
curvature of its cable specification and then cut the cable.
If you install 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.
Installing the Antenna
When you install the antenna, the antenna must be within the protective angle
(left/right side 45° each from the central axis) to prevent the antenna from
lightning damage.
Checking VSWR for Minimum Cable Bend Radius and Length of RF Cable
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.

SAFETY CONCERNS
Cautions When Measuring VSWR
When measuring VSWR, if you open 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.
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.
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.
Connection of Feeder Cable Connector
Connecting the feeder cable connector is critical process, so the qualified workers
who finished the related education should perform.
Installation
Cautions while Cleaning the Rack
Make sure that worker does not damage installed cables while cleaning the rack.
Do not Work by Yourself
Worker must not work alone in any key process.
Managing Unused Ports
Never allow foreign substances to be inserted into unused ports by covering them
with a dust cap.

cap) to prevent infiltration of foreign material such as dust, moisture, or bug.
Caution When Connecting the Optical Cable
Check whether there is dust or foreign material on the cutting section of the
connector core before connecting the optic cable, and keep this away from dust
or foreign material.
If the cable is soiled with foreign material, do not blow to remove them. Make sure
to clean the connector in accordance with the cleaning directions in ‘ANNEX D’.
Caution When Assembling Cable Gland
If the parts of a cable gland in the system are not correctly installed, outdoor air
and moisture may flow into the system and cause corrosion, system fault, or
serious fault to the cooling system.
Therefore, assemble and finish the cable gland accurately.
Caution When Installing Cable in the Cable Gland
Only one cable of permitted specification (thickness) should be installed in the
cable gland.
- The outdoor air or moisture may flow into the system if a cable that is thinner
than the specification is used.
- If a cable is thicker than the specification or more than two cables are installed,
the cable gland may be damaged.

2.2.2 Marking and Drilling
Marking
Before placing the system, mark the position where the system will be installed and also
the positions where anchor bolts will be fixed using an ink line or a pen.
Checking Marking (horizontal/vertical) When Mounting the System on Wall
If you do the drilling or anchoring on a wall when the positions are not marked to
be horizontal or vertical, only limited range of tuning is allowed for leveling after
the system is mounted.
To mount the system on a wall, perform the leveling test by referring to ‘System
Leveling’ to check the positions are marked to be horizontal or vertical before
drilling. If the result shows they are not horizontal or vertical, modify the marking
positions.
Marking Using the System
When the position where the system will be placed is determined, place the
system on the position and then mark the positions where anchor bolts will be
fixed using a pen. This will reduce marking error range caused by a worker.

CHAPTER 3. Connecting Cables
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.
Connect the ground cable first.
System Grounding Method
Ground bar for lightning protector/power/communication must be isolated from
each other. These three ground bars can be grounded as the isolation grounding
method, or branched from ground mesh buried in the underground as common
grounding method.

CHAPTER 3. Connecting Cables
Precautions When Connecting Power Cable
To secure rainproof performance of a cable gland, min. 11.81 in. (300 mm) straight
section must be maintained. Here, the radius of curvature must be considered
according to the cable specification.
≒ 11.81 in. (300 mm) or more
≒ 11.81 in. (300 mm)
Stainless Steel Band
or Cable Tie
≒ 11.81 in. (300 mm)
Precautions When Cutting Power Cable
Install the power cable to the power port of system by considering the radius of
curvature of its cable specification and then cut the cable.
If you install the cable after cutting, there may be length difference among the
