Contact data for main contactor/breaker control

￭

General

The main contactor or breaker is controlled by the drive through relay K3. The relay has
one normally-open (NO) and one normally-closed (NC) contact.
Emergency stop options add a relay (K640) to the drive. To trip the main breaker upon an
emergency stop, one of the output switchover contacts of K640 must be wired to the
undervoltage coil.
The contacts of both relays are wired to a terminal block in the drive cubicle; see the
drive-specific circuit diagrams for details. The external voltage switched by the contacts is
to be connected to the same terminal block.
