Installing a BTS3902E on a Wall

The wall on a BTS3902E is installed must meet the following requirements:

l When a single BTS3902E is installed, the wall has a capacity of bearing at least four times

the weight of the BTS3902E.

l Expansion bolts must be tightened to 30 N·m (265.52 lbf·in.) to ensure the bolts work

properly and the wall remains intact without cracks in it.

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.

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.
