Installing the RRU Cables RRU+BBU Installed Against the Wall DC RRU power cable CPRI optical cable BBU power cable PGND cable DCDU panel facing the side, and the BBU panel facing downward LOAD6 LOAD0 The DC RRU power cable is connected to one group of the LOAD0 to LOAD5 terminals of the DCDU-03B. When the BBU and RRU are installed indoors, the DC RRU power cables need not to be grounded.

Installing the RRU Cables RRU+TMC/TMC11H Grounding the shielding layer of the power cable: Metal Shielding layer PGND cable (25 mm [1 in.]) DC RRU power cable CPRI optical cable LOAD0 DC RRU power cable 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 Items 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.
Appendix 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.
