Relay contact data for control of external main
contactor/breaker
General
￭
The external 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 (K62) to the drive. To trip the main breaker upon an
emergency stop, one of the output switchover contacts of the relay must be wired to the
undervoltage coil.
Harmonics are below the limits defined in IEEE519.

THD = Total Harmonic Distortion (THD). The voltage THD depends on the short-
circuit ratio (R
). The spectrum of the distortion also contains interharmonics.

values, contact your local ABB representative.
500 m (1640 ft).
Note: Longer cables cause a motor voltage decrease which limits the available
motor power. The decrease depends on the motor cable length and characteristics.
Contact ABB for more information.
Note: With motor cables longer than 150 m (492 ft) the EMC Directive requirements
may not be fulfilled.
