Spare Part
• WPC5 power supply unit [03072955-xx]
• WPC6 power supply unit [03056701-xx)
Overview
The power supply assemblies (1), such as the transformer, relays and contactors, inrush current
limitation board etc. are fitted on an mounting plate (2) and can be removed as a complete unit.
The mounting plate is fixed with 4 screws to the WPC frame:
• 2 x side, front (3)
•
1 x on frame, left side (4)
•
1x on frame, right side - in cable duct (6)
Removal
➢ To gain better access to the power supply unit, dismantle the side covers and, if necessary,
the front cover. See section.
➢ Check whether all cables are labeled.
➢ Make sure that you are able to correctly assign all cables and plugs again. Where
necessary, label cables, plugs and connections for easier reconnection later.
DANGER
Voltage at cable to the main switch
When the WPC power cable is connected and the main switch has been turned off,
voltage is still present at the cable to the main switch, at the line filter and at the terminals
to the main switch.
Disconnect the WPC from the power supply.
