Operating the unit

Depending on model and connection variant, use switches provided by customer to switch the unit on and off. Barrier-free units do not need switches. Alternative connection options are described (Wiring diagrams).

If the unit is switched on and off manually, function in accordance with relevant standards is not always ensured.

In the event of thermal overload, the unit switches off automatically. Wait until the motor has cooled down. Cool-down time may be up to 10 minutes. The unit switches back on automatically after cooling down.
