5.6.1 Multi-function relay
The inverter is equipped with a multi-function relay as standard. This can be activated, for instance,
simultaneously with the red error LED beside the display. Other functions are being planned can be

Here you can connect separate loads both in the event of errors and for trouble-free operation.
The following table gives you the maximum permissible voltages and currents:
Cable requirements
The cable type and cable-laying method must be appropriate to the application and location.
Line circuit breaker
If you are connecting the multi-function relay to the public grid, it must be protected with a separate
line circuit breaker.
