24 V supply voltage

The MCC91A.. inverters have an internal 24 V voltage supply. The internal 24 V switched-mode power supply has an available power of 7.3 W.

As soon as a gateway is plugged into an inverter, the gateway must be supported with an external 24 V voltage supply. All other inverters connected to a gateway via a CFC11A communication module are supplied via the gateway and do not require an additional 24 V voltage supply.
