WARNING
When connecting the Digistart D3 in inside delta configuration, always install a main contactor or shunt trip
circuit breaker.
NOTE
When connecting in inside delta, enter the motor full load current (FLC) for Pr 1A. The Digistart D3 will
automatically detect whether the motor is connected in-line or inside delta and will calculate the correct
