7.7 3-phase “universal” wiring (models -/600 and over, & /-450 3-phase)
Fuses F1 are always present in this wiring design.
Fuses F2 are always present in G range models.
Fuses F3 are absent in standard G range models: wire size not reduced.
A model made to this diagram can be
converted by the customer between the
following supply voltages:
between 3-phase + neutral in the range
380/220V – 415/240V
and
3-phase delta in the range
200V – 240V
and
single phase in the range
200V – 240V
See also section 8.2 if there is a voltage
change.
