Safety guidelines
1) Short-circuit proof wiring or line protection recommended
Note
Acquisition of the line supply voltage
A voltage tap between the circuit breaker or fuse and the contactor is recommended for
acquisition of the line supply voltage.
Thus, when the motor is shut down, its operable state can be derived from the presence of
the supply voltage.
Note
Measurement of voltage or power-related variables
Connect the main circuit L1, L2, L3 of a current / voltage measuring module to the clamps
(L1, L2, L3) of the removable terminal with a 3-core cable. The supply cables may require
additional cable protection, for example via short-circuit proof cable or fuses.
Note
When connecting or routing the cables of the individual phases of the main circuit, ensure
correct assignment of the phases on the current / voltage measuring module and correct
routing direction!
Please note the information in the Operating Instructions. You will also find the Operating
