E6580516
Operating a large capacity motor with a light load using a small
capacity (kVA) inverter must be avoided. The output peak current will
increase due to the current ripple, and overcurrent trips may
frequently occur.
Power-factor improvement capacitors must not be
installed on the
inverter's output. When operating a motor with power-factor
improvement capacitors installed, remove the capacitors,
or
the
inverter may
fault trip or the capacitors may be damaged.

Use with voltage sources other than the rated voltage
is
not possible.
If
necessary, use a transformer, etc., to increase or decrease the
source
voltage to the rated voltage.
A
DSA (lightning surge absorber) is used for protection in the unit. If a
surge
voltage exceeding 2600 to 3600V peak is applied, the device
will light like a glowing electrical discharge. This will cause no
problems if the condition does not continue for an extended period of
time.
