Overview of replacing Inverter components
In the event of a permanent function fault, you can replace the Inverter's Power Module (PM)
or Control Unit (CU) independently of one another. In the following cases, you may
immediately switch on the motor again after the replacement.
WARNING
Recommissioning and removal of power before exchange of system components
1. In all other cases, you must recommission the drive.
2. When exchanging the Terminal Unit (which contains the Control Unit Module) or the
Power Module, the power supply and external 24 V supply MUST be removed from the
system before attempting any replacement of components.
Note
Memory card reader
The memory card reader is located on the side of the PM and is not accessible when the PM
is fitted to the CU.
