Setting the Functions of the Multifunction Relays


Qualified person

The multifunction relays of the master are preset in a single-cluster system for increased self-consumption and cannot be changed. In multicluster systems with Multicluster-Box 12 (MC-BOX-12.3-20), multifunction relays 1 and 2 in the master of the main cluster and multifunction relay 1 in slave 1 of the main cluster are set permanently. Furthermore, free multifunctional relays can be used for additional functions.

Note the function of the multifunction relays in the following table during the electrical connection Connecting the Components).
