Running with light loads:

Power-factor improvement

capacitors;

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:

Protection device for

lightning surges:

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.
