The following procedures describe the operation of the
electrical operator and addresses electrical operation,
The motor operator does not permit a breaker handle to
indicate its “TRIP” position. If it is desirable that the trip
position be indicated either of the following two methods
may be incorporated:
1. The breaker may be equipped with bell alarm con-
tacts which “MAKE” or “BREAK” upon automatic trip
operation. Contacts may be wired to an external light or
other indicating device to then indicate trip.
MAKE SURE THAT ALL SENSITIVE EQUIPMENT
CONNECTED TO THE LOAD SIDE OF THE CIRCUIT
BREAKER IS DISCONNECTED BEFORE OPERAT-

TIONS COULD CAUSE DAMAGE TO EQUIPMENT -
ESPECIALLY EQUIPMENT REQUIRING A CON-
TROLLED SHUTDOWN.
