Adding Load
Generally, the power system is not fully loaded at the initial operation stage. Power interrupt is not allowed once the priority load
is put into operation. Therefore, new load adding must be a live operation.
Before adding DC load, a good construction design must be worked out. Select the load fuse or MCB, process and lay the load
cables, and attach serial number and polarity labels to the cables. Cable connection should start from the load end. Connect the
earth cable first, and then the 336V output fuse or the MCB. The tools used must be insulated and preventive measures against
possible accidents must be worked out in advance. Refer to
1.1.2 Cables And Material Preparation
for DC load cable connection

Rectifier Expansion
Procedures for adding rectifiers:
1. Remove dummy plates.
Some rectifier guide rails are idle and covered with dummy plates when the power system is not fully configured. Before adding
rectifier, these dummy plates must be removed so that new rectifiers can be mounted.
2. Insert the new rectifier into position along the guide rail and fix it. See
1.6
Installing Rectifiers
.
3. Set the address in the controller for the corresponding rectifier.
4. Close the corresponding AC input switch to feed AC power to this rectifier.
5. Repeat steps 1 to 4 to add all rectifiers.
6. Reset parameters for controller.
NOTE!
Connection and disconnection of rectifier’s external input cables should be done by maintenance personnel, and
the cables must be connected before switching on the rectifier, and disconnected after switching off the rectifier. The
rated current of the rectifier input MCB is 63A, and its breaking capacity is 4.5kA.
