Installing the RRU on a U-Steel Plan view U-steel z The procedure for installing the RRU on a U-steel is the same as that for installing the RRU on a metal pole. z It is recommended that only one RRU be installed on a U-steel. Installing the RRU on an Angle Steel Plan view Angle steel z The procedure for installing the RRU on an angle steel is the same as that for installing the RRU on a metal pole. z It is recommended that only one RRU be installed on an angle steel.
Installing the RRU on a Wall 1. Place the auxiliary bracket at the installation position. Use a level to check that the auxiliary bracket is placed horizontally. Then, mark the anchor points by using a marking pen. ≥650 mm [25.6 in.] ≥650 mm [25.6 in.] 128 mm [5 in.] Level 126.5 mm [5 in.] 126.5 mm [5 in.] 1200 mm [47.2 in.] to 1600 mm [63.0 in.] RRU z It is recommended that the auxiliary bracket be 1,200 mm [47.2 in.] to 1,600 mm [63.0 in.] above the ground.
Installing the RRU on a Wall 3. Fit the auxiliary bracket on the expansion bolts downward, and then tighten the bolts by using a combination wrench 17 mm [0.7 in.]. M10 30 N•m [265.5 lbf•in.] Arrows are upwards 5. Install the RRU. 13 4. Install the main bracket.
Installing the RRU on a Wall 6. Install multiple RRUs. Recommended Clearance : ≥855 mm [33.7 in.] ≥855 mm [33.7 in.] ≥70 mm ≥70 mm [2.8 in.] [2.8 in.] Minimum Clearance: ≥655 mm [25.8 in.] ≥655 mm [25.8 in.
Installing the RRU Cables a RRU Cable Connections Single RRU Start Install PGND cable Antenna z When the length of the AISG multi-wire cable between the RRU and the RCU is not enough, you can choose the optional AISG extended cable between the RRU and the RCU. z If the coaxial cable is used for the RET antenna when the STMA or Smart Bias-Tee (SBT) is used, the OOK signals are required. Therefore, the port for the RET antenna needs to use the ANT_TX/RXA port.

Installing the RRU Cables i RRU+TMC/TMC11H Grounding the shielding layer of the power cable: a DC RRU power cable b CPRI optical cable Metal Shielding layer (25 mm [1 in.]) PGND cable LOAD0 DC RRU power cable z At the end of the DC RRU power cable connected to the DCDU-03B, you need to make the shielding layer of the power cable into an OT terminal, and then connect the OT terminal to the PGND terminal of the corresponding port on the DCDU-03B.
RRU Hardware Installation Checklist No. Items 1 All self-made PGND cables are copper-based with the proper wire diameters. No breaking device such as switch and fuse is allowed for the electric connection of the grounding system. No short circuit is allowed. Each terminal on the grounding bar can be connected with only one wiring terminal of the PGND cable. 2 The RRU and the installation parts are securely installed. 3 The cover plate is securely installed on the cabling cavity of the RRU.
Appendix a Binding the RRU and Installation Components 1. Bind the RRU by leading the lifting rope along the lower part of the adapting piece and through the handle, bind the main and auxiliary brackets with the lifting rope, and then bind the steering rope with the handle of the RRU, as shown in the following figures. Lifting rope Steering rope Lower part of the adapting piece z When lifting the RRU and installation components to the tower, prevent the RRU from colliding with the tower.
Appendix b Adding OT Terminals by Using a Wire Stripper (Recommended) Adding the OT terminals to the power cable involves adding OT terminals to the RRU power cable and adding OT terminals to the shielding layer of the RRU power cable. Label for preparing the power cable -48V DC power cable -48V DC power wire OT terminals Shielding layer GND wire Determine lengths of power cables for different operations according to the scales on the inner side of the cover plate of the cabling cavity.
Appendix c Adding OT Terminals to the Shielding Layer of the DC RRU Power Cable Lead the wires made of the shielding layers through heatshrinkable tubes. Wrap the PVC insulating tape at the joint where the three wires meet. WARNING Do not damage the shielding layer of the power cable when cutting around the jacket.
Appendix d Waterproofing Outdoor Cables z The waterproof tape should be wrapped for an extra length of 20 mm [0.8 in.] away from the connectors at both ends. z The tapes should be wrapped around the connector from the lower part to the upper part. When wrapped for another layer, the tapes may not be cut. z When wrapping the waterproof tape, apply even force to extend the tape until the width of the tape is 1/2 of the original width.
