Install the equipment according to the site survey's design drawing
Installation
and ensure that the equipment is within 45° protection of the
lightning arrester.
Ensure that the installation sequence of RRU parts is correct and
install the main equipment securely.
Ensure that the crimping clip closely presses the naked part of the
power cable's shielding layer in the maintenance window.
Grounding and
Waterproofing
Ensure that the RRU, outdoor power cable, and feeder's grounding
point comply with relevant requirements.
Check the antenna feeder's "1+3+3" waterproof protection and
ensure that the maintenance window is securely installed to avoid
water penetration.
Ensure that the grounding card's cable is routed downwards, the
angle between the grounding lead and the feeder is not larger than
15°. Remove the rust on the terminal of the grounding cable before
it is connected.
Cable Routing
Ensure a 20 cm vertical cable routing for RRU connectors and
antenna connectors, and that the protection caps of all unused RRU
connectors are tightly screwed.
Ensure that the remaining antenna feeders are wound into "S" or "8"
shape and the remaining fibers are wound on the wire spool and
stored in a proper place.
Ensure that a water trap is made for the cable that is led into the
equipment room and the lowest point of the water trap is 10 to 20 cm
lower than the bottom edge of the inlet port at the feeder window.
10
Ensure that outdoor cables are bundled by using black ties and a
section of 2 - 3 threads (3 - 5 cm) is reserved.
11
Ensure that all cables are connected securely and labels are hanged
properly at both ends.
12
Ensure that cables are routed properly and straightly, without any
crossing, obvious ups, downs and skews, or fly wire.

Installing the DC Junction
Box
This procedure describes how to install the DC junction box (ODCPD1).
TheZXSDR R8854 DC power connector cannot be connected to the power cable with the
sectional area of 10 mm2 or 16 mm2. If the power cable with the sectional area of 10
mm2 or 16 mm2 must be used because the distance between the ZXSDR R8854 and an
external power supply is too long, a DC junction box (ODCPD1) is needed to connect the
power cable to that with the section area of 4 mm2 or 6 mm2.
Steps
Installing the ODCPD1
1. Fix the mounting bracket of the ODCPD1 to the ZXSDR R8854 with four screws, see
Figure 9-1.

Caution!
The ODCPD1 can be installed by the back or the side. The installation position of it
should ensure that it can be opened at a 90° angle at least for easy maintenance.
2. Fix the ODCPD1 to the mounting bracket with two screws included with the ODCPD1,
see Figure 9-2.

4. Make the ends of the power cable according to the diagram on the inner side of the
cover plate, see Figure 9-4. Crimp the OT terminals of the external DC power input
cable and the DC power cable connector of the RRU. The part between the shielded
layer and the OT terminal must be wrapped with insulation tape.
Figure 9-4 Making a DC Power Cable Connector
5. Pass the DC power cable through the waterproof plug of the ODCPD1 and fix it to the
correct terminal, see Figure 9-5.
Figure 9-5 Securing the DC Power Cable
6. Close the cover plate of the ODCPD1 and evenly tighten the six waterproof screws on
the cover plate, see Figure 9-6.

7. Connect the other end of the DC power cable to the RRU and the external power
supply equipment respectively.
8. Bundle and label the cable.

Waterproofing Outdoor
Connectors
Waterproofing outdoor connectors is a "1+3+3" process, that is, wrapping one layer of
PVC insulating tape, three layers of waterproof insulating tape, and three layers of PVC
insulating tape around a connector.
The PVC insulating tape is used to prevent connectors from damage, ageing, and water
ingress.
Steps
1. Clean the cable connector and ensure that no dirt or oil stain exists on the connector.
2. Wrap a layer of electric insulation tape.
After a cable connector is connected, wrap the connector with the insulation tape
downwards in the direction that the connector is tightened, with each round covering
half of the previous round, see Figure 10-1. Ensure that the part about 10 mm to the
connector end is wrapped with the insulation tape. When wrapping the connector,
stretch the tape with proper force.
Figure 10-1 Wrapping a Layer of Electric Insulation Tape
3. Wrap three layers of waterproof tape.

SJ-20160405141455-003|2018-01-03 (R1.3)
ZTE Proprietary and Confidential
ZXSDR R8854 Hardware Installation
Extend the waterproof tape until its width is 50% to 75% of the original width.
Wrap three layers of waterproof tape in the direction that the connector is tightened
to prevent the connector from loosening. Wrap the connector upwards for the first
layer, downwards for the second layer, and then upwards again for the third layer,
with each round covering about one third of the previous round to prevent the ingress
of rainwater, see Figure 10-2. Do not cut off the tape before the connector is fully
wrapped with three layers. Ensure that the part wrapped with the waterproof tape is
more than 20 mm in length.
After wrapping the connector with the waterproof tape, grip and pinch the wrapped part
repeatedly with both hands to make the waterproof tape securely stuck to the cable
and the cable connector.
Figure 10-2 Wrapping Waterproof/UV Resistance Tape
Caution!
The outermost layer of tape shall be applied from the bottom up to avoid water
penetration.
4. Wrap three layers of UV resistance tape.
Wrap the connector with three layers of UV resistance tape in the same direction
of wrapping waterproof tape, see Figure 10-2. Pay attention to the following when
wrapping a cable:
The UV resistance tape should be stretched and wrapped with proper force to
prevent it from being stretched too much.
The upper-layer tape covers 1/2 the bottom-layer tape in length.
The wrapping length of the UV resistance tape must be 10 mm longer than that
of the waterproof tape. Wrap three layers.
After wrap three layers, grip and pinch both the UV resistance tape and waterproof
tape to ensure that they are securely adhered.
5. Secure the tape's two ends.

Chapter 10 Waterproofing Outdoor Connectors
After applying the tape, use black ultraviolet-proof ties to securely bundle the tape's
two ends, as shown in Figure 10-3. Use the diagonal pliers to cut off the excessive
ties and reserve a section of 3 mm at the mouth. This avoids tape expansion under
high temperature.

Labeling Specifications
Labels include indoor and outdoor labels.
Outdoor labels are hangtags that are delivered with the device.
Indoor labels are the self adhesive paper-printed labels that may need to be produced
at site if necessary.
Labels must meet the following requirements:
The special paster of ZTE Corporation must be used for paper labels.
Contents on rack row labels and column labels should meet the engineering design
requirements.
Boards should not be labeled and identifiers on a board should not be altered.
All labels should be attached to face the same direction. The side that indicates
where the cable is connected to should face upward or towards the operation and
maintenance position for the convenience of being read.
All cables such as the power cable, grounding cable, transmission cable, and feeder
should be labeled at both ends.
For optical fibers, network cables, and trunk cables, an indoor label should be pasted
20 mm away from the connector at both ends each.
Outdoor labels should be secured with cable ties at the same height and direction.
