11.5 Installation
This section details how to connect the -48 V DC supply to the DC load.
Check that all the MCB breakers and the AC mains supply are in the OFF position.
Unscrew the cabinet's four top fixing screws and slide top-cover forward before lifting it up. Enter each load
cable in to the cabinet trough the inlet at the back of the cabinet.
Connect the negative (-) load DC supply cable to the appropriate negative DC distribution MCB by inserting
the stripped cable in the opening on top of the MCB and tightening the screw. Make sure the cable is the
correct rating (i.e. thick enough) for the selected MCB.
Connect the positive (+) load DC supply cable directly to the positive busbar by inserting the stripped cable
to the hole on top of the screw connector so that the cable is behind the busbar, and then tightening the
screw. Start connecting the loads to the busbar from the first connector on the left. Make sure, the cable is
the correct rating (i.e. thick enough) for the load.
Check, that all the cables are secured tightly to the connectors. Use Torque Table in the Maintenance and
troubleshooting chapter for the correct torque.
