Danger to life due to live cables
If an insulated wire, e.g. L1, L2 or L3 comes loose from the AC terminal, and touches the
connection cable of the ripple control receiver for example, the connection cable is live.

• Attach the protective cover of the

multifunction relay. This isolates the AC
connection area in the inverter from other
terminals.
