Figure 42 GFW connection example for 3 independent loads in open delta, 3-phase line without neutral
(*)IMPORTANT:
Take care
to connect
terminals 1/L1
and 3/L1 to the
same phase
(**)Only required
with Vload

Figure 43 Example of GFW3-PH wiring for 3 indipendent single-phase loads
It is possible to connect three single-phase loads also to three different line voltages, between line to line or line to neutral.
It is possible to manage by Fieldbus different power values for each one of the three loads.

Take care
to connect
terminals 1/L1
and 3/L1 to the
