Step

Operating instruction

5 / 6

Mount a DIN rail in the center of the base of the door-

coupling rotary operating mechanism. Attach the

deactivated motor starter protector to the DIN rail from

above and snap the motor starter protector onto the

DIN rails.

7 / 8

Replace the cover on the base of the door-coupling

rotary operating mechanism. When doing this, make

sure that the motor starter protector is set to "OFF" and

that the shaft slot is on the right.

Opening the door

To open the control cabinet door, set the motor starter protector to O. This will release the

extension shaft from the rotary operating mechanism so that you can open the door.

Opening the door with significant force

Note
Opening the door with a force of ≥ 800 N when the motor starter protector is set to I can

damage the mechanism beyond repair. The motor starter protector remains active. The

mechanism will keep the door closed up to a force of 800 N.
