Overvoltage protection

Activate the evaluation of an external message signal. The inverter can evaluate the message output of the overvoltage modules (SPD) and output a message if an event occurs. Information on connection and wiring can be found under Connecting the signal contact for the external overvoltage protection (SPD – Surge Protective Device).

INFO

The settings in this menu can only be configured after logging in as the installer.
