Line Contactor Start Control
The MSC-3 can be optionally congured so that it is powered by a customer supplied external 24V
DC supply independent of the mains power supply. In this mode the MSC-3 is capable of controlling an
external line contactor to apply mains power to its own power circuits. The MSC-3 remains operational
if either or both 24V DC or mains power is present. In order to control the external line contactor, one of
the MSC-3’s relays must be congured with the “AUX_PWR” function. The diagram below illustrates the
wiring.
