Safety information and use notice points
3
inverter output and the motor, please guarantee the inverter is switched on/off
without output, otherwise may damage the inverter.
(8) The inverter may meet with mechanical resonance of the load within certain
range of frequency output, can set up jumping frequency to evade.
(9) Before using, should confirm the voltage of the power is within the working
voltage 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 graph1-1 and insulation resistance should not be
smaller than 5 M
Ω
, 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, shown 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.
