6.4 Analogue load sharing
If hardware option M12 is installed, the controller can use analogue load sharing lines to share the load equally (as a percentage of
the nominal power). Analogue load sharing can be used for both the active and/or the reactive load.

When is analogue load sharing active?
Analogue load sharing is active automatically when:
• The mains breaker is open and the genset breaker is closed. That is, the connected genset is not parallel to the mains (island
operation).
◦ You can use M-Logic to disable analogue load sharing.
