➢ Remove all cable fixtures (cable ties etc.) and disconnect all cables and plugs from the
power supply unit.
➢ For connection details and complete circuit diagrams, please refer to the following
documentation:
➢ Detailed circuit diagrams [00196627-xx] German/English
➢ Loosen the 4 fastening screws (3), (4) and (6).
➢ Disconnect the ground terminal (5) from the mounting plate of the power supply unit.
➢ Remove the mounting plate with the complete power supply unit from the WPC, by pulling
the power supply unit out to the side.
CAUTION
! Heavy weight of the power supply !
When pulling out the mounting plate, make sure you always provide support from below as the
transformer is very heavy and the plate could bend if support is not provided.
➢ The power supply assemblies are now accessible for further service work, such as
replacement of the lines filter, rectifiers or transformers.
Strain relief on the power supply unit
(example of WPC6 shown)
➢ When pulling out the power supply (1),
take care of the strain relief.
