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
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.
CAUTION
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.

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) Connect a lead of an insulation tester to the Hex.bolt for fixing the RRH-2WB.
2) Connect another lead to the anchor bolt.
3) 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
such as the system’s internal components and the unit (system frame),
components of the communication cables, units, etc. should not be measured.

The cabling sequence is as follows.
Figure 3.1 Work Flow for Cabling
Cabling Workflow
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’.
Considerations when Cutting the Cable after Installation
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.

CHAPTER 3. Connecting Cables
3-2 © SAMSUNG Electronics Co., Ltd.
Cable Path Inspection
When installing a cable that connects between the rectifier, Main Ground Bar (MGB), and
backhaul device, etc. within the system, the cable path length and the cable installation
method, etc. 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.
The cable must be placed in a location where it will not be damaged by external
factors. (power line, flooding, footpaths, etc.)
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, etc.)
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.
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.
Always use the maximum curvature radius possible, and make sure that the minimum
curvature radius specification is complied with.

Cable Binding
Cable binding involves fixing and arranging an installed cable using binding strings, cable
ties, binding lines, and ram clamps, etc.
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,
etc.) and the use of the cable (power supply cable, optical cable, feeder line, etc.).
Do not let the cutting section of a cable tie and binding line, etc. be exposed to the
outside. This may cause damage to cables or personal injury. Make sure that the
cutting sections of cables are not exposed to the outside.
If there is a danger that contact failure may occur in a connector connection due to
tension, install the cable as short as possible.
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 you are 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 connector.
Trim the remaining string of any knot in a binding string so that the knot does not loosen.
CHAPTER 3. Connecting Cables
3-4 © SAMSUNG Electronics Co., Ltd.
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,
etc. to the both ends of a cable (connections to a connector) to identify its use and cabling path.
Marker Cable Tie
On the marker cable tie, a label can be attached.
The appearance and specification may differ depending
on the type and manufacturer.
Follow these guidelines when attaching an identification tag.
When installing a cable outdoor, use relief engraving and coated labels, etc. 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.
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.
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.
Cable Installation Checklist
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.

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, over-
voltage, 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.

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.

Checking Feeder Connection
After connecting the feeder cables, perform the continuity test and feeder cable return loss
to check if the feeder cable is changed and measure VSWR of antenna and feeder cable.
Measure all cables of section ~. 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.
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.

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 Inter-
Modulation 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-2 © SAMSUNG Electronics Co., Ltd.
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.

B.3 Tower Ground Construction
1) Install a Tower Ground Bar (TGB) that will be used to ground a feeder cable onto the
tower. If the height of the tower is exceeds 20 m (65.62 ft), two or more TGBs should
be installed (onto the lower and upper sections of the tower). If the tower is 20 m
(65.62 ft) or less, one TGB should be installed. Since the TGB installation location and
the number of TGBs to be installed can differ depending on the system environment
and provider’s standards, consult your service provider.
2) Each TGB should be grounded and separated from other grounds. If there is an
existing ground bar or ground cable for TGB, install the TGB by branching from it
using a ground cable (AWG 1, GV 35 mm2 × 1C) ground cable. (However, the
specification of TGB ground cable can be different, defending on the standard of
service provider.)
3) Tighten the ground kit (feeder cable grounding assembly) to the TGB ground terminal
