Installing
4.3 Activation via F-DI
Components in separate control cabinets
If the components are located in separate control cabinets, the wiring between the I/O
modules and the F-DIs on the inverter must be installed such that it is protected against
cross and short-circuits.
Transfer the two signals for activating a safety function via wires in separate lines. In the
example, the signals for terminal 5 and 7 are transferred via the first wire. The signals for
terminal 6 and 8 are then transferred via the second wire.
