objects into the inverter.
12. .For inverters that have been stored for more than half a year, a charging experiment should
be conducted before use to restore the characteristics of the filter capacitor of the inverter
main circuit. When charging, the voltage regulator should be used to gradually increase the
voltage to the rated value. Within 1~2 hours, otherwise there is a risk of electric shock or
explosion.
13. Since the output voltage of the inverter is a PWM pulse wave, please do not install capacitors
or inrush current absorbers at its output. If it has been installed, be sure to remove it.
14. It is strictly forbidden to use contactors and other switching devices on the input side of the
inverter to directly start and stop frequently.
15. Derating is required for areas with an altitude of more than 1000 meters. -Generally, the
derating is about 10% every 1000 meters.ć
16. If there are abnormal phenomena such as smoke, odor, strange noise, etc. in the inverter,
please immediately cut off the power and carry out maintenance or call the agent for service.
17. When carrying out inspection and maintenance, the main circuit power should be cut off first.
18. The company will not be responsible for any loss of property and personnel caused by
unauthorized modification of the inverter or failure to follow the procedures in this manual.
