With Step-down
Autotransformer
and using a 120/
240 Vac Generator The following instructions are illustrated in Figure 3-20, “Generator Input
Wiring to a Single Inverter” on page 3–37 .
To install the AC wiring from the generator to the inverter:
1. Connect GROUND (green or bare) wires:
a) from the generator GROUND connector to the Step-down
autotransformer GROUND connector,
b) from the Step-down autotransformer GROUND connector to the
generator disconnect switch GROUND connector, and
c) from the generator disconnect switch GROUND connector to the
inverter AC GROUND bar.
2. Connect NEUTRAL (white) wires:
a) from the generator NEUTRAL connector to the Step-down
autotransformer NEUTRAL connector,
b) from the Step-down autotransformer NEUTRAL connector to the
generator disconnect switch Neutral connector, and
c) from the generator disconnect switch NEUTRAL connector to
the inverter NEUTRAL 2 terminal.
3. Connect HOT (black) wires:
a) from the generator L1 HOT OUT to the Step-down autotrans-
former L1 HOT IN,
b) and from the generator L2 HOT OUT to the Step-down autotrans-
former L2 HOT IN,
c) from the Step-down autotransformer HOT OUT to the generator
disconnect switch HOT connector, and
d) from the generator disconnect switch HOT connector to the
inverter AC2 GEN terminal.
4. Torque all inverter terminal block connections to 25 inch-pounds.
Without a
Step-down
Autotransformer
Using a
120 Vac-Only
Generator If not using a Step-down Autotransformer, install the AC wiring from
the generator to the inverter through the generator disconnect as
follows:
1. Connect GROUND (green or bare) wires:
a) from the generator GROUND connector to the ground in the
generator disconnect, and
b) from the ground in the generator disconnect to the ground bar in
the inverter.
2. Connect NEUTRAL (white) wires
a) from the generator NEUTRAL connector to the neutral in the
generator disconnect, and
