After wiring, short-circuit
U, V, W to measure
insulation resisitance.
range allowed, otherwise should vary voltage or order special inverter.
(10) In the condition of altitude above 1000 meters, should use the inverter in lower
volume, reduce output current by 10% of specified current after each 1500 meters height
increasing.
(11) Should make insulation check to the motor before using it for the first time or after
a long time placement. Please inspect with 500V voltage-type megohm meter according to
method shown as graph 1-1 and insulation resistance should not be smaller than 5MΩ,
otherwise inverter may be damaged.
(12) To forbid assembling capacitor for improving power factor or lightning proof
voltage-sensible resistance etc., otherwise will cause malfunction trip of the inverter or
damage of the parts, show as graph 1-2

1.4 Scrap notice points
When disposing scrap inverter and its parts, please note:
(1) The unit: please discard as industrial useless.
(2) Electrolytic capacitor: when burning the inverter electrolytic capacitor in it may
explode.
(3) Plastic: when plastic, rubber parts etc. in the inverter are burning, they may bring bad,
poisonous gas, so please be ready to safeguards.
