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.
