Precautions for Wiring
Otherwise, you run the risk of electric
shock or
fire.
Be sure to ground the inverter.
Entrust wiring work to a qualified electrician.
Before wiring, be sure to turn off the power
supply and wait for 10 minutes or more.
(Confirm that the Charge lamp on the inverter is
off and the DC voltage between
N is 45 V or less.)
Otherwise, the inverter may fail.
Do not pull the wire after wiring.
Otherwise, you run the risk of injury or
fire.
Do not connect AC power supply to
output terminals (U, V, and W).
Make sure that the voltage and frequency of AC
power supply match the rated voltage (AC input
voltage) and frequency of your inverter.
Otherwise, you run the risk of electric
shock and injury.
Before operating the slide switch SW in the
inverter, be sure to turn off the power supply.
Since the inverter supports two modes of
cooling-
fan operation, the inverter power is not
always off, even when the cooling fan is
stopped. Before
to turn off the power supply and wait for 10
minutes or more. (Confirm that the Charge
lamp on the inverter is off and the DC voltage
between terminals P and N is 45 V or less.)
Prevent the distribution cable from being
compressed or getting caught to avoid damage
to the cable.
