6.1 Installing BS8900 Cabinet (BC8910+RC8911) Installation Steps

Installation Figures 1 If the BC8910 and RC8911 cabinets are installed in pile or in parallel, first decide the location of the cabinets and mark the punching positions with the base (see Figure 1).

2 Punching: a. Punch in the marked positions with an electric impact drill (drill bit with a diameter of 10mm). b. The depth of the holes is between 50mm and 60mm (see Figure 2)

3 Install expansion bolts: a. Knock the expansion bolt into the hole and make the expansion tube enter the ground completely; b. Remove the bolt, nut, spring washer and flat washer from the hole. They will be used to install the cabinet base.

4 Place the cabinet on the top of the base, and tighten the screws.

5 Lift the cabinet with the base, and let the expansion bolts go through to the holes of the

cabinet. Then add flat washers, spring washers and nuts and tighten the nuts with a wrench (see Figure 3).

Figure 1 6 Check if the cabinet has been fixed steadily. It should not move when pushed by hands.


1 If the cabinets are installed in pile, requirements of its location are as follows: the distance between the cabinet back and the wall should be at least 400mm, and the front space should be at least 800mm. If there is equipment near the flank sides of the cabinet, the distance should be at least 200mm. And at least 200mm of space should be reserved above the rack top.

7.5 Connecting & Distributing Master Feeders Installation Steps

Installation Figures 1 Determine the feeder length for each sector according to the project design drawings.

2 Cut the feeder and mark on them. The actual feeder length should be 1~2m more than the designed length (see Figure 1).

3 The feeders should be laid neatly from the outdoor to the indoor. At the same time, tighten the feeder triple clip. Usually one triple clip is used for every 1m. And the clip should be vertical to the feeder (see Figure 2).

4

Neatly arrange the feeder according to the feeder sequence in the project design documents and the room-entering scheme. Fix the triple clip to the iron tower or the cable tray. Make sure the feeders do not cross (see Figure 3).

Figure 1 Figure 2 5 Install the feeder ground clip and connect it to the outdoor ground bar or outdoor cable tray (the tray has already been grounded). Refer to 7.5.2 Installing and Making Feeder Ground Clips to get detailed information.

Installation Figures 1 Determine the installation position of the feeder ground clip according to the site configuration and the feeder length.

2 Cut the sheath of the feeder to expose the external metal part, which shall be as long as the feeder ground clip (see Figure 1).

3 Cover the metal part with the feeder ground clip and tighten it (see Figure 2).

4

Make waterproof treatment on the exposed part of the feeder. Refer to 7.5.5 Waterproof Measures for Equipment Connectors (see Figure 3).

Figure 1 Figure 2 5 Rub and remove the antirust paint from the nearest ground bar or outdoor cable tray (the tray has already been grounded). After the installation, it is necessary to spray the anti-rust paint or coat butter to avoid rusting (see Figure 4).

6 Lead the ground cable of the feeder ground clip to the nearest ground bar or outdoor cable tray (the tray has already been grounded) and make reliable connection (see Figure 4).

7.5 Connecting & Distributing Master Feeders Installation Steps (to be continued in next page)

Installation Figures 1 Before making the waterproof treatment, firstly clean off the dusts and dirt from the connector.

2 Wrap the PVC insulating tape from left to right and from the bottom upward. The upper layer covers 1/2 of the lower layer. PVC insulating tape should cover the entire feeder connector so that the waterproof insulating tape will not adhere to the connector (see Figure 1).

Then wrap the waterproof insulating tape. Unfold the waterproof insulating tape, remove the release paper and paste the tape end to the point 20~50mm under the connector (with the gelatinous layer inward) (see Figure 2).

Figure 1 Figure 2 4 Stretch the waterproof insulating tape evenly to make its width shrink to 75%~50% of the original width and keep certain elasticity. Wrap the connector from left to right and from the bottom upward. The upper layer covers 1/2 of the lower layer (see Figure 3).

5 When the waterproof insulating tape reaches 20~50mm above the connector, wrap from the top downward to 20~50mm beneath the connector in the same way, and finally wrap from the bottom upward again. Therefore, 3 layers of waterproof insulating tape are required (see Figure 4 and 5). (to be continued in next page)

Procedure Item 7.7.1 Installing Antennas and Connecting Cables

7.7 Installing Antennas and Connecting Cables Installation Steps

Installation Figures 1 All the antennas must be installed securely. They shall not move and should meet the wind-resisting requirements. The poles installed at the rooftop must be grounded and located within the lightning-protective range.

2 The antenna port is at one end of the antenna. There are two red protective caps on the jumper connectors. The two ports at the bottom are the electrically regulated ports (see Figure 1).

3 Carefully hold the antenna, fix the installation rack to the pole, put the flat washers, spring washers and nuts in sequence and finally slightly screw the nuts with hands (see Figure).

4

Adjust the antenna installation position, horizontal angle and vertical angle, and tighten the nuts (see Figure 4).

Figure 1 Figure 2 5 The azimuth error of the directional antenna should be within ±5°. And the pitching error of the directional should be within ±0.5°. And the single-polarized antennas in the same sector should have consistent pitching angle and azimuth angle.


1 The antenna should be within the protective range of the lightning rod, which means that the lightning rod should be higher than the antenna. Protective angle: not more than 45° in the plain and not more than 30° in high mountains and thunder-dense areas.

2

To ensure safety, security measures should be taken before the antennas are installed.

If the antenna is installed to the iron tower, it is required to lift it to the tower top: a) Bind the upper side and the lower side of the antenna installation rack respectively

with two ropes. b) To prevent the antenna from hitting the tower body, during the lift, one person

should take one of the ropes and lift the antenna upward; another person should take anther rope to adjust the rack.

c) Because working on the tower top is very dangerous, it is recommended to use the crown block to lift the antenna.

7.8 Checking Equipment Power-up/Power-down Installation Steps

Installation Figures 1 Check if the AC/DC power cables, and the PGND cable at the BS8900 side have all been connected correctly. And check if the DC power cables at the AC power cabinet side have been connected correctly.

2 Check and make sure the power switches at both the BS8900 side and the AC power cabinet side are in the OFF state (see Figure 1).

3 Use a multimeter to test if the voltage at the AC power cabinet side is normal (see Figure 2). If it is normal, power up the AC power cabinet by turning ON the power switch.

4

Use a multimeter to test if the AC input terminal at the back of the BC8910 power subrack is normal. If it is normal, power up BBU and heat exchanger by turning ON the switches (see Figure 2), and test if the DC output terminal voltages of BBU and PDM are normal or not.

Figure 1 5 Turn on the corresponding switches of the DC output terminals of BBU and PDM, and observe the states of the indicators of all the boards and modules (see Figure 3).

6 After the power-up check, turn OFF the PDM and BBU power supplies, then the BBU and heat exchanger power supplies, and finally the general switch at the side of AC power cabinet.
