Backstop

Description
The backstop is used to block a direction of rotation of the motor. The blocking direction is defined as seen onto the fan guard.
Specification of blocking direction:
CCW (Clockwise)
CCW (Counterclockwise)
The backstop is installed instead of the brake.
The locking torque reaches at least double the maximum motor torque, (Exception: DRS132MC4 only reaches 160 %).
Similar to the installation principle of the brake (integrated or premounted on a friction disk), the backstop can also be installed in different ways.
