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 considered.
Caution for cutting the power cable
Cut power cable after installing power cable to RRH-P4A 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.
Caution When Connecting Optical Cables
Before connecting an optical cable, make sure that there is no dust or foreign
substance on the cross-section of the connector core. If there is any dust or
foreign substance, do not remove it by blowing with your mouth. Remove 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 system (RRHP4A) with a new one.

SAFETY CONCERNS
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.
Caution When Connecting RET Cable
Make sure to turn off the breaker connected to the RRH-P4A power of the DU
cabinet before connecting the RET cable between the antenna RET port and the
RRH-P4A RET port.
If you connect or disconnect the RET cable while the breaker is turned on, it may
cause an electric short circuit resulting in damage to the RET function.
Installation General
Caution when losing External Power Cable Support Bracket
External Power Cable Support Bracket and two cable tie (stainless steel) for fixing
cable are enclosed in RRH-P4A 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 insertion hole: After installing cable, finish insertion hole using
tape, compressed sponge, rubber packing, silicon, etc. to prevent empty space.

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 cable 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.

SAFETY CONCERNS
RRH-P4A optic cable connection standard
Cable connection standard between UADU CPRI port and RRH-P4A 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.
Caution when Installing the RF antenna
To protect from lightning, the RF antenna must be installed within the shielding
angle as shown below, considering the downward distance and the angle from
the tower lightning rod or the antenna pole lightning rod.
- The protection angle of the lightning rod should be 45 degrees.
Finishing Heat Shrink Tube of a Sector Antenna
1)
Insert an antenna protection plate.
2)
Place the heat shrink tube on the connection point and shrink the heat shrink
tube using a heat gun.

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

When connect the connector to the antenna, not making the alien substance flowed and
is not under the influence of PIMD.

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)
2)
3)
4)
Use the transit to adjust the antenna installation direction exactly.
Fix the direction of the sector antenna, same as the angle settled when designing the
cell after installing the steel tower.
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.
For circular platform, separate the antenna interval at maximum.

ANNEX A. Sector Antenna Installation
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.
2) Set the antenna’s up/down tilt to 0° and fix the fixing clamps at the top and bottom.
3) After tightening the fixing clamp, adjust the antenna up/down (tilt) depending on the
signal strength. The bolt of the guide clamp must be loosened, so the antenna angle can
be adjusted.
4) After setting the antenna angle, fasten the bolt of the guide clamp, which was loosened
previously. Regarding the nut, the double nut mounting should be used to prevent the
nut from coming loose.

If the height of the tower is more than 65.62 ft. (20 m), two or more TGBs should be
installed (onto the lower and upper sections of the tower). If the tower is 65.62 ft.
(20 m) 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 2, GV25 mm2 × 1C) ground cable.
3) Fasten the Ground Kit (feeder cable grounding assembly) to the TGB ground terminal
and the tower hole using the pressure terminal hole attached at the end of the ground
kit’s ground cable.
