A 3-phase supply via a suitable protective device (such as a circuit breaker) should be connected to the
inverter as shown (Terminals L1, L2, L3, PE). A suitable MF welding transformer/rectifier should be
connected to the inverter at terminals H1 and H2. The transformer must also be connected to the
protective earth (PE).
Additional earthing and/or a protective device is required for the secondary circuit depending on the

These tasks must only be carried out by qualified personnel.
