1.1 Grounding is not required if the feeder or jumper is less than 5 m. 1.2 You should ground the feeder on the RRU side if the feeder is greater than 5 m but less than 20 m.

2. When the RRU is installed outdoors and far away from the antenna (greater than 20 m, and main feeder is used),

2.1 You should ground the feeder on the RRU side. 2.2 You should ground the feeder on the antenna side. 2.3 If the feeder is laid on an iron tower, you should ground the feeder before it leaves the tower. If the distance from the tower to the RRU is less than 10 m, grounding is not required for the feeder before it leaves the tower. If the length of the feeder on the tower is greater than 60 m, you should ground the feeder at the middle position of the tower.

3. When the RRU is installed indoors, 3.1 You should ground the feeder at the very position before it goes through the feeder window of the equipment room. 3.2 You should ground the feeder on the antenna side. 3.3 If the feeder is laid on an iron tower, you should ground the feeder before it leaves the tower. If the distance from the tower to the feeder window is less than 10 m, grounding is not required for the feeder before it leaves the tower. If the length of the feeder on the tower is greater than 60 m, you should ground the feeder at the middle position of the tower.

4.4.2 Grounding Clips for Power Cables 1.

2 1-3-31 -3 -3

2. 1-3-31 -3 -3

1. Outdoor shielded DC power cables must be grounded near the feeder window of the equipment room, and the grounding clips must be connected to an outdoor grounding busbar. If the cable is grounded after it enters the equipment room through the feeder window, the cable where a grounding clip is applied must be wrapped with two layers of insulating tape. If the cable is grounded before it goes through the feeder window, the position of a cable where a grounding clip is applied must be processed with the 1-3-3 water-proof measure, that is, one-layer insulating adhesive tape, three-layer waterproof adhesive tape, and three-layer ultraviolet-proof adhesive tape. 2. Outdoor shielded DC power cables must be grounded before they enter an outdoor cabinet, and the grounding clips must be connected to an outdoor grounding busbar. The position of a cable where a grounding clip is applied must be processed with the 1-3-3 water-proof measure, that is, one-layer insulating adhesive tape, three-layer waterproof adhesive tape, and three-layer ultraviolet-proof adhesive tape.

5. Waterproofing and Grounding Outdoor Cables

R8881 1 +3 +3 The outdoor optical fiber and connector of the R8881 should be wrapped with two layers of ultraviolet-proof adhesive tape. The other outdoor cable connectors and grounding clips should be spiral-wrapped by using one-layer insulating adhesive tape, three-layer waterproof adhesive tape, and three-layer ultraviolet-proof adhesive tape. Here we take a feeder connector for example to explain the waterproof measure: 1.

10 mm 1. Spiral-wrap one layer of insulating adhesive tape: After the feeder is connected, spiral-wrap one-layer insulating adhesive tape around the connector with 50% overlapping, ensuring that an excess of 10 mm insulating adhesive tape is reserved at the tail of the connector. Remember that you must apply proper force while spiral-wrapping the insulating adhesive tape.

2. 50cm / 2. Spiral-wrap three layers of waterproof adhesive tape: Stretch the waterproof adhesive tape two times as long as its original length. Use approximately 50 cm waterproof adhesive tape for each connector. Spiral-wrap three-layer waterproof adhesive tape around the connector in the direction that you tighten the feeder. This can protect the feeder from being loosened during the spiral-wrapping process. Smooth over the waterproof adhesive tape by applying proper force to secure it on the feeder.

20 mm Note: You must spiral-wrap the first layer from bottom up, the second layer from top down, and the third layer from bottom up with one third overlapping. This can protect the connector against rain and moist. Do not cut off the waterproof adhesive tape during the spiral-wrapping. Ensure that an excess length of 20 mm waterproof adhesive tape is reserved at the tail of the feeder.

3. 3 1/2 10 mm

3. Spiral-wrap three-layer ultraviolet-proof adhesive tape around the connector in the same way as the waterproof adhesive tape, with 50% overlapping. Ensure that an excess length of 10 mm ultraviolet-proof adhesive tape is reserved at the tail of the waterproof adhesive tape. Smooth over the ultraviolet-proof adhesive tape by applying proper force to secure it on the waterproof adhesive tape.

4. 3mm

4. Tighten both ends of the adhesive tape using black ultraviolet-proof cable ties in order to keep them adhesive. Cut off the excess length of the cable tie using diagonal pliers. To avoid being loosened in high temperatures, reserve an excess length of 3 mm on the cable tie.
