personnel in advance.
10. When the inverter is powered on, do not open the cover or perform wiring work.
11. Do not touch the inside of the inverter after power-on, and do not put conductive rods or other 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.
。
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.
