Danger
● Be sure to turn off the input power supply before wiring.
● Do not touch any internal electrical circuit or component when the charging lamp is still on
after the AC power supply is disconnected, which means the inverter still has high voltage inside and
it is very dangerous.
● Do not check components and signals on the circuit boards during operations.
● Do not dissemble or modify any internal connecting cord, wiring or component of the inverter
by yourself.
● Be sure to make correct grounding connection of the earth terminal of the inverter.
● Never remodel or replace control boards and components by yourself. It may expose you to an
electrical shock or explosion, etc.
！ Caution
● Do not make any voltage-withstanding test with any component inside the inverter. These
semi-conductor parts are subject to the damage of high voltage.
● Never connect the AC main circuit power supply to the output terminals U.V W of the inverter.
●The main electric circuit boards of CMOS and IC of the inverter are subject to the effect and
damage of static electricity. Don’ t touch the main circuit boards.
● Installation, testing and maintenance must be performed by qualifed professional personnel.
● The inverter should be discarded as industrial waste. It is forbidden to burn it
