Operator - Operating Instructions.
4.3.1 Motorized Operator
Caution

Be sure to apply the operating (control) voltage shown on the accessory nameplate to the
motor operator. (The permissible operating voltage ranges from 85 to 110% of the rated
voltage.)
Undervoltage or overvoltage may cause burnout.

The motor is rated for short-time. Repeated open/close operation should not exceed 10
times.
If repeated continuous open/close operation is inevitable, a pause of at least 15 minutes
should be provided after the repetitions of 10 times.
Otherwise, burnout could result.

The indicator permits you to check if the ACB is open (ON) or closed (OFF). Red shows ON,
green OFF, and white TRIPPED.
Electrical check can also be done using the auxiliary switch for ON or OFF state and the alarm
switch (optional) for TRIPPED state.
