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 inter-

hole spacing. If the spacing is too wide or too narrow, drill holes again. Tighten each expansion bolt slightly and place them perpendicularly into each hole. 3. 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 Nm (221.27 lbfin.), as shown in Figure 7-14.

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. Tighten the thread-lock sealing nut, and then use a wrench to tighten the PG connector to ensure it is waterproofed properly. 3. 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 Nm (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.

Issue Draft A (2011-06-30) BTS3902E WCDMA Installation Guide 1. 8 Installing an AC Surge Protection Box and Related Cables 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. Tighten the thread-lock sealing nut, and then use a wrench to tighten the PG connector to ensure it is waterproofed properly. 3. 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 Nm (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.

Step 2 If the power cable is longer than or equal to 5 m (16.4 ft.), cut the corrugated pipe into multiple 5-meter-long pieces; if the cable is shorter than 5 m (16.4 ft.), cut the corrugated pipe based on the actual length of the power cable. 9-28 Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. Issue Draft A (2011-06-30) BTS3902E WCDMA Installation Guide 9 Installing Cables NOTE Following is based on the power cable longer than or equal to 5 m (16.4 ft.). Step 3 Lead the power cable through corrugated pipes, and add a connector between two corrugated pipes, as shown in Figure 9-28. Figure 9-28 Leading the power cable through corrugated pipes Step 4 Join the corrugated pipes, as shown in Figure 9-29. Figure 9-29 Joining corrugated pipes Step 5 Determine the length of the power cable for different operations based on the labels, as shown in Figure 9-30.

GE) cable. 9-30 Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. Issue Draft A (2011-06-30) BTS3902E WCDMA Installation Guide Procedure 9 Installing Cables Step 1 Determine the position for installing the ground clip on the cable based on the actual cable route. Step 2 Use a utility knife to strip the sheath off the FE/GE cable for about 32 mm to expose the shield layer, as shown in Figure 9-34. CAUTION Do not damage the shield layer when stripping the sheath off the cable. Figure 9-34 Stripping the sheath off the FE/GE cable Step 3 Install the ground clip on the shield layer of the cable, and then use a screwdriver to tighten the screws on the ground clip, as shown in Figure 9-35.

Issue Draft A (2011-06-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 9-31 9 Installing Cables BTS3902E WCDMA Installation Guide CAUTION l Wrap the tape around the clip 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. l The degree between the ground cable and the FE/GE cable is not greater than 15. When the FE/GE cable is routed vertically, the ground cable must be routed downwards. Figure 9-36 Wrapping waterproof tape and PVC insulation tape
