NOTICE
When connecting the VLT
inside delta configuration, always install a main
contactor or shunt trip circuit breaker.
NOTICE
When connecting in inside delta, enter the motor full
load current (FLC) for parameter 1-1 Motor FLC. The MCD
500 automatically calculates inside delta currents based
on this data. Parameter 15-7 Motor Connection is set to
Auto detect as default and can be set to force the soft
starter in inside delta or in-line.
