3.1Wallmounting
In most cases, two expansion bolts are enough to fasten the mounting bracket, which
should pass through the upper two screw holes on the face of the bracket. However, if the
ZXSDRR8881S4200is installed along a high-speed railway, in a tunnel or an
earthquake-prone zone, four expansion bolts are required.
1. Use an electrical punch drill to drill 2 or 4
holes on a wall. And then fix the
attachments of the expansion bolts into the
holes. Use a vacuum cleaner to clean the
dust while you are drilling holes
2. Place the mounting bracket on the wall.
Then use two M10x100 expansion bolts to
pass through the upper two screw holes on
the bracket and screw up the bolts to fasten
the bracket on the wall, In placing the
bracket, ensure the arrow on the bracket
points upward.
3. Use four M6 hexagon socket head bolts,
each with a spring washer and a flat washe
r
on, to fix the RRU support on the back of a
ZXSDR R8881 S4200.
4. Remove the screw in the middle of the
mounting bracket.
5. Fit the hangers of the RRU
support into the grooves of
the mounting bracket.
6. Reinstall the screw that is removed
in Step 4 and tighten it to fasten the
RRU.
3.2Installing12ZXSDRR8881S4200onthepole
Note:
1. The diameter
of the pole
ranges from
60mm to 120
mm. If the
diameter is no
more than 90
mm, a pad (as
shown in the
left figure)
should be used
in tightening
the
bolt;otherwise,
the pad is not
necessary.
2. The width of
the angle steel
should range
from 60 mm to
100 mm; and
the width of the
channel steel
should range
from 63 mm to
100 mm.
1.Put a fixed bolt through the installation holes (in the
middle) of each mounting bracket.
2. Place the two mounting brackets on a pole in a back-to-back manner and put the fixed
bolts into the bolt grooves on the opposite brackets.
Pole Diameter > 90 mm Pole Diameter ≤ 90 mm
3. Tighten the bolts to fix the mounting brackets on the pole.
4. Remove the screw in the middle of each mounting bracket.
5. Fit the hangers of the RRU support into the grooves of the mounting bracket.
6. Reinstall the screw that is removed in Step 4 and tighten it to fasten the RRU.
7. This installation method is applicable to the installation of one or two ZXSDR R8881
S4200s.
3.3InstallingtheODCPD1
When a 16mm2 power cable is used, the ODCPD1 is required.
1. Use four screws to fasten a mounting frame in the front of the device.
2. Use two screws to fasten the ODCPD1 on the mounting frame.
3. If two devices are installed in parallel, the ODCPD1s should be installed in
this way: one is in the front and the other is at the back of devices respectively.

IMPORTANCE:
The power port of a DC-type ZXSDR R8881 S4200 is a two-core round connector (with
pins). The DC power cable that is made at the site for the DC-type ZXSDR R8881 S4200
must be connected to the correct port on a DC power supply device
otherwise, the ZXSDR R8881 S4200 may be damaged.

3. If the ODCPD1 is used, use one grounding wire to connect the GND port of
ZXSDR R8881 S4200 to the grounding point of the ODCPD1, and then use
another grounding wire to connect the grounding point of the ODCPD1/PIMAC to the
nearest outdoor grounding busbar.
4.2.3ConnectingtheRFjumpers
Connect two feeders to the ANT1 and ANT2 ports of the ZXSDR R8881 S4200
respectively.
4.2.4 ConnectingtheOpticalFiber
1. Remove the protection cap from the optical fiber. Then, detach the outer protection
cover.
2. Remove two white covers. 3. Insert the optical fiber into the OPT1
port until it locks into place with a
click sound.
4. Insert the transparent sleeve into
the OPT1 port fully.
5. Fasten the outer protection cover of the fiber
until the yellow mark is exposed.
6. The optical fiber is thus
connected to the OPT1 port of ZXSDR
R8881 S4200.
7. In case of cascading, connect the optical fiber to
the OPT2 port of the upper-level ZXSDR R8881 S4200 and
the OPT1 port of the lower-level ZXSDR R8881 S4200.

RXout port of the local R8881 to the RXin port of the remote ZXSDR R8881 S4200.
4.2.8MakingandInstallingaPowerCable
1. Remove the bottom cover and the shell from a power connector.
2. Let a power cable pass through the bottom cover and the shell.
Note: If the 2x10 mm2 cable is used, the rubber ring inside the connector shell should be
removed. If the 2x4 mm2 or 2x6 mm2 cable is used, the rubber ring should be kept.
3. Loosen the four screws that hold the positive and negative wires and one screw that
holds the shielding wire on the connector head.
4. Follow the instructions on the
connector drawing to process the
cable.

correct holes of the power connector (The blue wire
is negative and the black wire is positive).
6. Insert the shielding wire of the cable to the
shielding wire hole.
7. Tighten the four screws for positive
and negative wires of the power cable.
You should tighten the two screws that
are close to the connector head first,
and then the other two screws.
8. Tighten the screw for the shielding wire.
Note: After the five screws are all tightened, the
cable should
not be loosened under a pulling force of 2 Kg.
9. Use a wrench to hold the connector
protection cover, and another to tighten
the shell. The torque to tighten the
shell should not be less than 1.2 N·m.
10. Use a wrench to hold the connector shell, and
another to tighten the bottom cover. The torque to
tighten the cover should not be less than 1.2 N·m.
11. After the power connector is made, you must test it with a multimeter. The connector
should meet the following requirements:
The holes are not short-circuited.
The connector shell and the hole are not short-circuited.
The shielding layer of the cable is conductive to the metal shell of the connector.
The wire of the cable is conductive to the corresponding hole of the connector.

ZXSDR R8881 S4200 power cable according
to the drawings inside the ODCPD1 cover.
4. Crimp four lugs onto the ends of
power wires.
5. Fix the power cables with the clamps
on the ODCPD1.The 16mm2 power cable
should be on the right, and the ZXSDR
R8881 S4200 power cable on the left.
6. Use screws to fasten the black wires
on the -48VGND terminal.
7. Use screws to fasten the blue wires
on the -48V terminal.
8. Fasten the cover of ODCPD1 with 6
screws.
4.3SelectingPositionsforGroundingClips
4.3.1GroundingClipsforAntennaFeeders
1. When the RRU is installed close to the antenna,
1.1 Grounding is not required if the feeder or jumper is less than 5 m.
1.2 You should ground the feeder on the RRU side if the feeder is greater than 5 m but
less than 20 m.
2. When the RRU is installed outdoors and far away from the antenna (greater than 20
m,and main feeder is used),
2.1 You should ground the feeder on the RRU side.
2.2 You should ground the feeder on the antenna side.
2.3 If the feeder is laid on an iron tower, you should ground the feeder before it leaves
the tower. If the distance from the tower to the RRU is less than 10 m, grounding is not
required for the feeder before it leaves the tower. If the length of the feeder on the tower is
greater than 60 m, you should ground the feeder at the middle position of the tower.
3. When the RRU is installed indoors,
3.1 You should ground the feeder at the very position before it goes through the feeder
window of the equipment room.
3.2 You should ground the feeder on the antenna side.
3.3 If the feeder is laid on an iron tower, you should ground the feeder before it leaves
the tower. If the distance from the tower to the feeder window is less than 10 m, grounding
is not required for the feeder before it leaves the tower. If the length of the feeder on the
tower is greater than 60 m, you should ground the feeder at the middle position of the
tower.
4.3.2 GroundingClipsforPowerCables
1. Outdoor shielded DC power cables must be grounded near the feeder window of the
equipment room, and the grounding clips must be connected to an outdoor grounding
busbar. If the cable is grounded after it enters the equipment room through the feeder
window, the cable where a grounding clip is applied must be wrapped with two layers of
insulating tape. If the cable is grounded before it goes through the feeder window, the
position of a cable where a grounding clip is applied must be processed with the “1-3-3”
water-proof measure, that is, one-layer insulating adhesive tape, three-layer waterproof
adhesive tape, and three-layer ultraviolet-proof adhesive tape.
2. Outdoor shielded DC power cables must be grounded before they enter an outdoor
cabinet, and the grounding clips must be connected to an outdoor grounding busbar. The
position of a cable where a grounding clip is applied must be processed with the “1-3-3”
water-proof measure, that is, one-layer insulating adhesive tape, three-layer waterproof
adhesive tape, and three-layer ultraviolet-proof adhesive tape.
