In the event of a device fault, interrupt the power supply immediately. Inform the customer
service personnel responsible. Malfunctions can occur when the operator controls or power
cable are damaged or when liquids or foreign objects penetrate the device.

analysis. The intended use of the device has to be ensured.
The proper use of the device has to be verified with a function test on the system. This test
can detect programming, configuration and wiring errors. The test results have to be
documented and, if necessary, entered into the relevant documents that verify safety.
