4.1.3 - Monophase connection 230Vac
Electrical drawing
Generator contactor TG1.
Terminals sequence:
T1-T2-T3-T4
Mains contactor TR1.
Terminals sequence:
T1-T2-T3-T4
Load connection X0.
Terminals sequence:
U-
V
-W-N
Load phase:
to use maximum terminals
power, poles U and V
must be connected
togheter; U+V=Phase.
These wires must pass
through the amperemetric
transformer before
connection to terminals U
and V
Load neutral:
to use maximum terminals
power, poles W and N
must be connected
togheter: W+N=Neutral.
A
mperemetric
transformer TA
Generator neutral:
to use maximum contactor
power, poles T3 and T4
must be connected
togheter; T3+T4=Neutral.
By this connection the
max current of the
contactor is Ith x 1,6
Generator phase:
to use maximum contactor
power, poles T1 and T2
must be connected
togheter; T1+T2=phase.
By this connection the
max current of the
contactor is Ith x 1,6
Mains phase:
to use maximum contactor
power, poles T1 and T2
must be connected
togheter: T1+T2=phase.
By this connection the
max current of the
contactor is Ith x 1,6
Mains neutral:
to use maximum contactor power,
poles T3 and T4 must be connected
togheter: T3+T4=Neutral. By this
connection the max current of the
contactor is Ith x 1,6
