1.Use a hammer drill with a φ12 bit to drill holes perpendicularly with the wall at the marked
anchor points. Ensure that the depth of each hole ranges from 55 mm to 60 mm (2.17 in.
to 2.36 in.).
WARNING
Take proper safety measures before drilling holes to protect your eyes and respiratory tract
against dust.
2.Use a vacuum cleaner to clear dust inside and around the holes, and then measure the interhole spacing. If the spacing is too wide or too narrow, drill holes again.
3.Tighten each expansion bolt slightly and place them perpendicularly into each hole.
4.Hit the expansion bolt using a rubber mallet to enable the expansion tube to completely
enter the hole.
5.Remove the M10x80 bolt, spring washer, and flat washer from each expansion bolt
assembly in sequence.
CAUTION
After disassembling an expansion bolt assembly, ensure that the top of the expansion tube
is on the same level as the wall. Otherwise, the BTS3902E cannot be installed on the wall
evenly and securely.
Step 4 Fit the mounting piece on the expansion bolt, and then use a combination wrench (17 mm [0.67
in.]) to tighten the expansion bolt to 25 N·m (221.27 lbf·in.), as shown in Figure 7-14.

NOTE
Do not use the removed thread-lock sealing nut of the PG connector with the thread-lock sealing nuts on
other surge protection boxes.
Step 2 Glide the thread-lock sealing nut and then the PG connector over the power cable.
Step 3 Connect the power cables to the AC surge protection box, as shown in Figure 8-18. The power
cable on the left connects the BTS3902E and the AC surge protection box, and the power cable
on the right connects the AC surge protection box and the external power device.

Installation Guide8 Installing an AC Surge Protection Box and Related Cables
1.Lead the power cable between the surge protection box and the external power device
through the PG connector labeled IN. Connect the OT terminals of the brown, blue, and
yellow/green core wires to the Lin, Nin, and GND ports on the surge protection box
respectively.
2.Route the power cable between the BTS3902E and the AC surge protection box through
the PG connector labeled OUT. Connect the OT terminals of the blue, brown, and green
and yellow wires to the Nout, Lout, and GND ports in the AC surge protection box,
respectively.
3.Tighten the thread-lock sealing nut, and then use a wrench to tighten the PG connector to
ensure it is waterproofed properly.
Step 4 Fasten the power cables using clips.
NOTE
Ensure that the insulation layer of each power cable is fastened using clips.
Step 5 Close the cover plate of the surge protection box and tighten the screw to 1.4 N·m (123.91 lbf.in.)
using an M4 Phillips screwdriver, as shown in Figure 8-19.
Figure 8-19 Closing the cover plate of the AC surge protection box
Step 6 Wrap the joints of the corrugated pipe and power cables using waterproof tape and polyvinyl
chloride (PVC) insulation tape, as shown in Figure 8-20. Wrap the joints using waterproof tape
before using PVC insulation tape.
TIP
Wrap each connector with three layers of waterproof tape, from bottom up, then from top down, and finally
from bottom up. Do not cut the tape until all the three layers of the tape are already wrapped. When wrapping
tape, be sure that each layer of tape overlaps more than 50% of the preceding layer.

lDifferent types of cables must be routed in parallel or separated by special objects.
Special Cabling Requirements
Cabling requirements for power cables are as follows:
lMultiple power cables must be bound when routed.
lPower cables must be installed in the position specified in engineering design documents.
lIf the length of power cables is insufficient, replace the cables rather than adding connectors
or soldering joints to lengthen the cables.
Cabling requirements for PGND cables are as follows:
lPGND cables for the base station must be connected to the same ground bar.
lPGND cables must be buried in the ground or routed indoors. They should not be routed
overhead before they are led into the equipment room.
lThe exterior of the coaxial wire and the shield layer of the shielded cable must have proper
electrical contact with the metal surface of the equipment to which they are connected.

8.4 Installing Cables for an AC Surge Protection Box
This section describes the procedure for installing cables for an AC surge protection box.
Prerequisite
Add OT terminals to the power cables for the AC surge protection box on the surge protection
box side. For details, see Adding OT Terminals to the Power Cable Connected to the AC Surge
Protection Box.
Procedure
Step 1 Loosen the screws on the AC surge protection box using the M4 Phillips screwdriver and open
the cover plate. Then, remove the thread-lock sealing nut from the PG connector of the surge
protection box, and store waterproof blocks properly, as shown in Figure 8-17.

NOTE
Do not use the removed thread-lock sealing nut of the PG connector with the thread-lock sealing nuts on
other surge protection boxes.
Step 2 Glide the thread-lock sealing nut and then the PG connector over the power cable.
Step 3 Connect the power cables to the AC surge protection box, as shown in Figure 8-18. The power
cable on the left connects the BTS3902E and the AC surge protection box, and the power cable
on the right connects the AC surge protection box and the external power device.

Installation Guide8 Installing an AC Surge Protection Box and Related Cables
1.Lead the power cable between the surge protection box and the external power device
through the PG connector labeled IN. Connect the OT terminals of the brown, blue, and
yellow/green core wires to the Lin, Nin, and GND ports on the surge protection box
respectively.
2.Route the power cable between the BTS3902E and the AC surge protection box through
the PG connector labeled OUT. Connect the OT terminals of the blue, brown, and green
and yellow wires to the Nout, Lout, and GND ports in the AC surge protection box,
respectively.
3.Tighten the thread-lock sealing nut, and then use a wrench to tighten the PG connector to
ensure it is waterproofed properly.
Step 4 Fasten the power cables using clips.
NOTE
Ensure that the insulation layer of each power cable is fastened using clips.
Step 5 Close the cover plate of the surge protection box and tighten the screw to 1.4 N·m (123.91 lbf.in.)
using an M4 Phillips screwdriver, as shown in Figure 8-19.

Step 6 Wrap the joints of the corrugated pipe and power cables using waterproof tape and polyvinyl
chloride (PVC) insulation tape, as shown in Figure 8-20. Wrap the joints using waterproof tape
before using PVC insulation tape.
TIP
Wrap each connector with three layers of waterproof tape, from bottom up, then from top down, and finally
from bottom up. Do not cut the tape until all the three layers of the tape are already wrapped. When wrapping
tape, be sure that each layer of tape overlaps more than 50% of the preceding layer.
