Power Factor Correction
CAUTION
Power factor correction must be switched in using a dedicated contactor. Installing power factor correction
capacitors with no contactor may damage the soft starter.
Power factor correction capacitors should be selected based on the motor data and the required final power factor.
Select a contactor according to the required kVAr.
The soft starter must control the power factor correction capacitor contactor. Use the PFC output (terminals 33, 34 on
the power interface board).

Capacitive surge arrestors
Capacitive surge arrestors are not compatible for use with soft starters. Using capacitive surge arrestors for motor
protection may damage the soft starter.
CAUTION
Capacitive surge arrestors may be mounted in the motor termination box. Check the motor datasheet and
check inside the termination box before connecting the soft starter. Disconnect any capacitive surge
arrestors.
