Setting up 24 V backup mode

All inverters that are connected to each other in a communication network and use the 24 V backup mode have to be supplied simultaneously with external 24 V. Make sure that individual devices that are connected in the network are not separated from 24 V.

INFORMATION

Errors in the fieldbus network may occur if the inverters are not supplied by the power supply and individual devices that are in the RJ45 network or the optional fieldbus network are separated from the external 24 V supply. Make sure that all connected inverters are always supplied with external 24 V at the same time.
The 24 V supply to the inverters must come via a diode terminal since the inverters could also supply other devices with 24 V, which can subsequently cause an overload of the internal switched-mode power supply and, under certain circumstances, cause damage as well.
