MOTOR OPERATOR
Electrical Control Using Motorised Operation
Motorized Operation
The motor operator has an input-signal self-hold circuit: closing the ON or OFF switch (see circuit diagrams shown below) momentarily allows activating the
motor operator. To reset the tripped breaker to the OFF position, close the OFF (RESET) switch.
The voltage presence LED indication is on when the power is supplied to the motor operator.
Manual Operation
Pull the operating handle out. Rotating the handle counter clockwise turns ON the breaker and clockwise turns OFF or resets the breaker.
Operation Precaution
1. Ensure that the actual operation voltage ranges from 85% to 110% of the rated one.
2. Use operation switches whose ratings and power capacity is as specified in the "Ratings and Specifications" table on the previous page.
3. Use noise filters if the control power supply of the motor operator is shared by peripheral devices. Otherwise, power supply noise may cause malfunction of
the peripheral devices.
