Possible Cause
● Main input circuit protection has opened.
● Control power fuse has opened.
● Safety circuit is open.
● Motor overload must be reset.
● Loose control wire connection.
The short circuit protection supplied by the factory is
approximately 1.5 times the NEC listed motor current rating.
Some applications and motor characteristics may require up-
sizing this protection. If this is required in the field, ensure that
there is an appropriate match between the types of fuses and
rating with the fuse holder.
