8. Load (AC Output) Connection
CAUTION:
To prevent continued supply to the load from the inverter during any mode of
operation, a disconnection device must be installed in the building distribution box
WARNING!
It's very important for system safety and efficient operation to use the
appropriate cable for AC connection. To reduce risk of injury, use the recommended cable
size as listed below:
Model
2KW,
3KW
3KW Plus
Nominal Grid Voltage
101/110/120/127 VAC
208/220/230/240 VAC
Conductor cross-section (mm
2
)
4 ~ 6
AWG no.
10 ~ 12
Step 1:
Remove insulation sleeve 8 mm for three
conductors. Shorten L and N conductors to 3 mm.
Refer to chart 8
(right)
.
Step 2: Connect wires according to polarities indicated on terminal block.
Be sure to connect PE protective conductor (
) first
Refer to Chart 9

Step 3:
Make sure the wires are secure. The tightening torque is 0.8 N.m.
CAUTION:
Connect load ONLY to “AC Output Connector”.
NEVER
connect the utility to
“AC Output Connector”.
CAUTION:
Be sure to connect L terminal of load to L terminal of “AC Output Connector” and
N terminal of load to N terminal of “AC Output Connector”. The G terminal of “AC Output
Connector” is connected to ground of the load.
CAUTION:
This inverter is not allowed to operate in parallel with another unit. This will
damage the inverter, and is not covered by warranty!
