4.9 Mounting a fail-safe frequency converter
Fail-safe applications are configured basically the same as standard applications but with the
following differences:
● Mounted to the left of the frequency converter must be a module through which the safety
functions of the frequency converter can be actuated, for example:
– an F-RSM repair switch module
– an F-Switch
● Only the following modules are allowed to be connected between the F-RSM or F-Switch
and the fail-safe frequency converter:
– 400 V shutdown module
– all direct or reversing starters
– the standard frequency converter
– the fail-safe frequency converter
Procedure:
Mount one after the other:
1. Rack
2. Interface module
3. Bus module for F-RSM or F-Switch
4. Bus module for frequency converter
5. Terminating module
6. Connection module for the interface module
7. F-RSM or F-Switch
8. Frequency converter
