Electrical Connections To The Pqf-Manager User Interface - ABB PQFM Instruction Manual

WARNING: Make sure that the phase rotation of the power cable connection is
clockwise at the filter terminals and that the L1, L2 and L3 terminal in each cubicle is
connected to the same phase for all cubicles. Failure to do so may lead to the filter
being damaged upon startup.
WARNING: Once a new filter unit has been added to a filter system, this unit has to be
given a unique address (through DIP switch setting on its control board). In addition,
the filter unit has to be recommissioned.
If more than one unit is added, it is recommended to first finish the hardware
modifications and then set up the controller accordingly. More information on how to
change the filter controller unit settings can be found in
After making and verification of all the electrical connections:
- Set a unique address on each filter unit control board
- Restore the filter protecting grids
Close the auxiliary fuse box of the filter units
-
Reclose the filter units
