may cause the damage of the equipment or the bodily injury of the worker. Connect the ground cable first.

Installation General

Caution for Laser Beam of Optical Module and Cable

The optical module and cable used in the system emit bright laser beams.

Always handle them with care as there is risk of serious injury if the eyes are exposed to the laser beam of the optical cable.

Wearing protection gloves and goggles

Make sure to wear protection gloves and goggles to prevent damages from debris

while drilling holes in a wall or ceiling.

CAUTION

Power and Feeder line

Caution for cleaning the 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.

Caution for installing the power cable

To maintain cable gland's rain protection performance, 300 mm or more interval

should be kept straight. According to the radius of curvature of the cable specification should be considered.

Stainless steel Band

or Cable Tie

≒300mm or more

≒300mm

Caution for cutting the power cable

Cut power cable after installing power cable to RRH-C2A power terminal taking

into account the radius of curvature according to the cable specifications.

When cutting the cable first, the length difference of cable end can be occurred by

cable curvature and the power terminal may cause contact fault.

TABLE OF CONTENTS

Caution for connecting power cable to power tap (‘2.7.3 Connecting RRH-

- Before connecting power cable to the power tap, connect the appropriate ring lugs

- Insert wire of power cable to ring lug head more than 10mm.

- After inserting power cable, fasten the screw by torque 11 kgf.cm.

Caution When Connecting Optical Cables

Before connecting an optical cable, make sure that there is no dust or foreign

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 General

Caution when losing External Power Cable Support Bracket(‘2.6 Connecting

ground cable’)

External Power Cable Support Bracket and two cable tie (stainless steel) for

fixing cable are enclosed in RRH-C2A package. Be careful not to lose when unpacking package.

Managing unused port

Finish unused port of UADU by dust-cap, not making the alien substance flowed.

Smart MBS RRH-P4 Installation Manual/Ver.2.0

Finishing Cable Insertion Hole

Finishing work is required on cable insertion holes (Cable gland, Conduit and

etc.) to prevent entering of any foreign substance, external air and moisture.

- Unused cable insertion hole: Finish cable insertion hole using fishing materials such as dust cap, rubber packing and etc.

- Cable-installed insertion hole: After installing cable, finish insertion hole using tape, compressed sponge, rubber packing, silicon, etc. to prevent empty space.

Do not work by yourself

Do not work by yourself in any key process.

Caution for cleaning the Rack

Make sure that worker does not damage installed cables while cleaning the rack.

Cautions When Connecting the CRPI Cable

Failure to observe the CPRI cable connection specified in Table 2.5 may impair

the communication between the CDMA terminal.

RRH-C2A optic cable connection standard

Cable connection standard between UADU CPRI port and RRH-C2A optic port is

different according to the count(One or two) of CDMA UADU(Installed in DU cabinet).

Connect the optic cable(Refer to the connection standard of 'table 2.6' and 'table

2.7'). Because false connection can cause the fault of call connection, be cautious.
