may cause the damage of the equipment or the bodily injury of the worker .
Connect the ground cable first.
Caution When Opening and Closing Power Window Cover
Make sure to turn off the breaker connected to the RRH-P4 power before opening
or closing the power window cover of the RRH-P4.
If you open or close the power window cover when the breaker is turned on, it
may cause damage to the s ystem, or cause an electric short circuit resulting in
severe injury.
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 prote cti on glov es and gog gle s to prevent dama ge s fro m debri s

CAUTION
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, 11.81 in. (300 mm) or
more interval should be kept straight. According to the radius of curvature of the
cable specification should be consider e d.
Caution for cutting the power cable
Cut power cable after installing power cable to RRH-P4 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 cau se contact fault.
Caution When Connecting Optical Cables
Before connecting an optical cable, make sure that there i s no dust or foreign
substance on the cross-section of the connect or core. If t here i s any dust or for eign
substance, do not remove it by blowing with your mouth. Remov e the dust or
foreign substance by referring to the method of cleaning optic connector.
Caution on Rain-proof Gasket Damage When Installing Window Cover
Be careful so as not to let the rain-proof gasket get damaged (broken or
incorrectly positioned). Check whether the rain-proof gasket is damaged before
closing the power window cover and the optic window cover.
If the rain-proof gasket is damaged, replace the s ystem (RRH-P4) with a new
one.

Installation General
Caution when losing External Power Cable Support Bracket (‘2.6 Connecting
ground cable’)
External Power Cable Support Bracket and two cable tie (stai nles s steel) for fix ing
cable are enclosed in RRH-P4 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.
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 insert ion hole: After installing cable, finish inse rtion hole usi ng tape,
compressed sponge, rubber packing, silicon, etc. to prevent empty sp ace.

Caution when assembling the cable gland
Ensure that all parts of the cable gland are assembled in the correct sequence.
Incorrect assembly may result in influx of external air or moisture into the system
and may cause corrosion, system malfunction and/or critical failure of the cooling
system.
Caution when installing the cable in the cable gland
Only one cable of permitted specification (radius) should be installed in the cable
gland.
- Installing a cable of smaller radius than the permitted specification may result in
influx of external air or moisture into the system and may cause corrosion or
system malfunction.
- Installing a cable thicker than the permitted specification or installing two or
more cables in the gland may damage the gland.
Caution when loosen and tighten the Cable Gland Nut
In case of assembling the c able gland and cabling, do not loosen and tighten by
turning the cable gland body or other parts. turning the cable gland body may
cause corrosion and system failure by entering of any external air and moisture.
Checking assembly state of the unused cable gland
All components of the unused cable gland must be secured in the original factory
configuration. If the cable gland nut is fitted without the rain protection filler or the
protection cover in place, reassemble them as illustrated in ‘Figure 2.7.’
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 and LTE FDD terminal.
