Preparations for commissioning

The controller may only be commissioned following installation at the place of use and connection of the control air and the electrical power supply.

The power supply and the electrical connections inside the housing must be checked before commissioning. The controller must not be operated without a fuse, loose connections must be tightened before commissioning.

Make sure that:

• the assembly has been correctly carried out,
• the controller is connected to the correct control air
• the control air supply is in operation and a pressure test for the control air has been performed
• the circuit breaker is not tripped
