Wiring Option 3
120/240V split phase
Input: Hot line+ Hot line +Ground
Output: Hot line +Neutral
Remark: In this case, each output
hotline can only carry a max of half
the rated capacity.
For Model #
APC3012D/APC3024D/APC3048D/
APC4012D/APC4024D/APC4048D/
APC6024D/APC6048D
Caution:
Wiring Option 2 and Wiring Option 3 are only allowed for split phase models.
Please wire all the other models according to Wiring Option 1.
For split phase models, AC input neutral is not required in wiring. Never
Connect Input Neutral to Ground or to Output Neutral. Otherwise damage will
occur which is not covered under warranty.
The output voltage of this unit must never be connected in its input AC terminal,
otherwise, overload or damage may occur.
Always switch on the inverter before plugging in any appliance.
Damages caused by AC wiring mistakes are not covered under warranty.
Note:
As the two split phase hot lines are 180 degrees out of phase with each other, the inverter is only able
to output full power at 240Vac.
Users can only get 50% nominal power from each one of the 120Vac hot lines of the split phase
inverter.
The biggest 120V single load the inverter can drive is 50% of its nominal power.
Preventing Paralleling of the AC Output
The AC output of the unit should never be connected to the utility power / generator.
Such a connection may result in parallel operation of the different power sources and AC power from the
utility / generator will be fed back into the unit which will instantly damage the inverter and may also pose a
fire and safety hazard.
