5.7 Single-phase loads

The 3-phase generators of this series can be used as single-phase, taking into account the indications provided
below:
The generator can be used for a maximum power equal to 0.6 times the power specified on the
nameplate for the 3-phase load.
The generator can be connected according to a star pattern in parallel (required voltage 220 Volt at 50 Hz or
220-240 V at 60 Hz) and the single-stage load must be connected to clamps U1/T1 and V1/T2.
