3.2 Installing 12 ZXSDR R8881 S4200 on the pole Note: 1. The diameter of the pole ranges from 60mm to 120 mm. If the diameter is no more than 90 mm, a pad (as shown in the left figure) should be used in tightening the bolt;otherwise, the pad is not necessary. 2. The width of the angle steel should range from 60 mm to 100 mm; and the width of the channel steel should range from 63 mm to 100 mm. 1.Put a fixed bolt through the installation holes (in the middle) of each mounting bracket.
2. Place the two mounting brackets on a pole in a back-to-back manner and put the fixed bolts into the bolt grooves on the opposite brackets.
3. Tighten the bolts to fix the mounting brackets on the pole. 4. Remove the screw in the middle of each mounting bracket.
5. Fit the hangers of the RRU support into the grooves of the mounting bracket. 6. Reinstall the screw that is removed in Step 4 and tighten it to fasten the RRU. 7. This installation method is applicable to the installation of one or two ZXSDR R8881 S4200s.
3.3 Installing the ODCPD1 When a 16mm2 power cable is used, the ODCPD1 is required.
1. Use four screws to fasten a mounting frame in the front of the device.
2. Use two screws to fasten the ODCPD1 on the mounting frame. 3. If two devices are installed in parallel, the ODCPD1s should be installed in this way: one is in the front and the other is at the back of devices respectively.

must be connected to the correct port on a DC power supply device otherwise, the ZXSDR R8881 S4200 may be damaged. 4.2.2 Connecting the Grounding Wire 1. Connect one end of the grounding wire to the GND port at the bottom of the ZXSDR R8881 S4200. 2. Connect the other end of the grounding wire to the nearest outdoor grounding busbar. Note: When you connect cables, you should connect the grounding wire first and the power cable last.
4.2.3 Connecting the RF jumpers Connect two feeders to the ANT1 and ANT2 ports of the ZXSDR R8881 S4200 respectively.
4.2.4 Connecting the Optical Fiber 1. Remove the protection cap from the optical fiber. Then, detach the outer protection cover. 2. Remove two white covers. 3. Insert the optical fiber into the OPT1 port until it locks into place with a click sound.
4. Insert the transparent sleeve into 5. Fasten the outer protection cover of the fiber the OPT1 port fully. until the yellow mark is exposed. 6. The optical fiber is thus 7. In case of cascading, connect the optical fiber to connected to the OPT1 port of ZXSDR the OPT2 port of the upper-level ZXSDR R8881 S4200 and R8881 S4200. the OPT1 port of the lower-level ZXSDR R8881 S4200. 4.2.5 Connecting the AISG Cable Connect the AISG cable to the AISG port of the ZXSDR R8881 S4200.
4.2.6 Connecting the MON Cable Connect the MON cable to the MON port of the ZXSDR R8881 S4200. 4.2.7 Connecting the Frequency Spreading Cable In the case of frequency spreading, use a frequency spreading cable to connect the RXout port of the local R8881 to the RXin port of the remote ZXSDR R8881 S4200.
4.2.8 Making and Installing a Power Cable 1. Remove the bottom cover and the shell from a power connector. 2. Let a power cable pass through the bottom cover and the shell. Note: If the 2x10 mm2 cable is used, the rubber ring inside the connector shell should be removed. If the 2x4 mm2 or 2x6 mm2 cable is used, the rubber ring should be kept. 3. Loosen the four screws that hold the positive and negative wires and one screw that holds the shielding wire on the connector head.
4. Follow the instructions on the connector drawing to process the cable. 5. Insert the positive and negative wires to the correct holes of the power connector (The blue wire is negative and the black wire is positive). 6. Insert the shielding wire of the cable to the shielding wire hole. 7. Tighten the four screws for positive and negative wires of the power cable. You should tighten the two screws that are close to the connector head first, and then the other two screws. 8.
9. Use a wrench to hold the connector 10. Use a wrench to hold the connector shell, and protection cover, and another to tighten another to tighten the bottom cover. The torque to the shell. The torque to tighten the tighten the cover should not be less than 1.2 N·m. shell should not be less than 1.2 N·m. 11. After the power connector is made, you must test it with a multimeter. The connector should meet the following requirements: The holes are not short-circuited.

Fix the power cables with the clamps on the ODCPD1.The 16mm2 power cable should be on the right, and the ZXSDR R8881 S4200 power cable on the left. 6. Use screws to fasten the black wires on the -48VGND terminal. 7. Use screws to fasten the blue wires on the -48V terminal. 8. Fasten the cover of ODCPD1 with 6 screws.
4.3 Selecting Positions for Grounding Clips 4.3.1 Grounding Clips for Antenna Feeders 1. When the RRU is installed close to the antenna, 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.
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.
5 Installation Check SN Checking Items Result 1 The protection grounding wires of the equipment are properly installed to the nearest copper grounding busbar. Pass □ Fail 2 Before connecting protection grounding wires, rust or dust should be removed from the surface of the grounding terminal to ensure reliable connections. Pass □ Fail 3 The naked wires and the copper lugs of power cables or grounding wires should be covered with a tube or wrapped with insulating tape.
