Connecting DC power to the Transceiver Unit
Dedicated power cables are used to connect the DC power from the Power Supply Units to the TRXU subracks in the Transceiver Unit. The physical connections are made from the terminal block in each Power Supply Unit to the terminal block on the rear side each TRXU subrack.

The power cables transfer the DC and AC power from the Power Supply Units to the Transceiver Unit. The cables must be installed in steel conduits to remove electric noise, avoid interference, and offer physical protection. The cables are included in the MS70 delivery, and they are provided readily connected to the terminal blocks in the Power Supply Units.
Note
Do not connect any AC or DC power to the Transceiver Unit or Power Supply Units until explicitly instructed to do so in the relevant procedure.
