While cleaning the power supply device, take caution that the device does not come

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.

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.
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.

Observe the following safety instructions when installing the RRH-2WB:
Before Installing
Post warning signs in areas where high-voltage cables are installed.
Post ‘off limit’ signs in areas where accidents are most expected.
With guardrails or fences, block open areas such as connecting parts, roof, and scaffold.
While Installing
The power must be cut off before installing.
Be careful that boards mounted on the system and the cables among the boards are
damaged or scratched when the system is transported or installed.
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.

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.
Watches, Rings, and Other Metallic Accessories Do not wear accessories such as watches and rings in order to prevent electrical
shock.
Do not Work by Yourself Worker must not work alone in any key process.
System Installation and Access
Only authorized workers are allowed to install or access the system.
Before starting the construction, the constructor and the departments concerned with the
construction inspect the following items with a pre-survey checklist for the smooth progress
of the construction. If any insufficiencies or problems are found, make the plan upon
deliberation with the departments.
Installation/construction personnel and the service provider carry out the site survey for the
system installation focusing on the following items:
Examination about the conformance and the economical efficiency of the place that the
system is transported or installed.
Status of external interfaces
Power capacity and wiring status
Possibility of system extension
Review if the place has the enough space to operate and maintain.
The basic tools for installation are listed in the table below. The additional tools required for
each site need to identified and prepared during a site survey before starting installation.

Precautions when Using the Installation Tools The required installation tools may vary depending on the conditions at the site.
In addition to the basic tools, a protractor, compass, GPS receiver, ladder, safety
equipment, cleaning tools etc. should also be prepared in consideration of the site
conditions.
System Installation Spaces The space specifications in the Figure above apply when the pole diameter is 101.6

2.2.2 Marking and Drilling
System marking helps install the system in a precise location by marking the locations of the
system, anchor bolts, and cable racks on the floors, walls, and ceilings. When marking is
completed, drill holes for anchor bolts.
1) On the location of the system installation, mark the positions of the equipment and
anchor bolts as shown in the Figure below.
2) Drill holes to insert the anchor bolts and cover the holes with acetate tape before
installing the system.
This paragraph describes the work to unpack cabinets and other components and transport
them to the place to be installed. The cabinet is externally packed and cabinet and other
components are individually packed.
The external packing should be unpacked in the outside. If necessary, the packing can be
unpacked after transported into the area near installation place.
Transport the cabinet to the installation place. Beware of the damage of walls, pillars, and
bottom of the passage when transporting the cabinet.
Transport other components with packing and sort by types.
2.3.1 Importing Items
Bring in items, taking care of the followings:
Regarding equipment weight and size, check the path to bring the equipment.
Lay Iron and veneer boards on stairs or doorsills to make the transportation easy.
When bring in equipment, beware of damage or impairment of main entrance, walls,
pillars, and floors of the station. Prepare protection materials and fix them with a highstrength adhesive.
Carry boards in packing status, and unpack them when installing or mounting.
Vibration Level for Transportation
When carrying the system, fasten the system firmly not to exceed the proper vibration level
from 1 to 500 Hz.
When carrying system, use a lift to prevent accidents. However, if the system should be
carried by people, enough people are required to carry the system.
Before moving the system, check the storage place for the system and remove obstacles in
advance. While moving system, boards and other devices should not be shocked physically
and damaged caused by dust, moisture, and static electricity.
When installing the items imported, system must be installed in a location whose access is not
easy from outside.
2.3.2 Unpacking Items
The procedure to unpack items is as follows:
1) The packing items should be packed until they reach the installation place.
2) The items are classified in accordance with each job specification and stored on a place
that does not interfere with working.
3) Unpacked systems should be installed immediately. If not installed immediately, the
systems should be stored in the installation place temporarily.
4) Unpack only external packing, leaving the internal packing in unpacked status.
5) Unpack the inner packaging after each system is placed on its installation location.
6) Do not recycle packaging waste. Dispose of it in consultation with the provider.
