Danger
l
Be sure to turn off the input power supply before wiring.
l
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.
l
Do not check components and signals on the circuit boards during the operation.
l
Do not dissemble or modify any internal connecting cord, wiring or component of the inverter by
yourself.
l
Be sure to make correct ground connection of the earth terminal of the inverter.
l
Never remodel it or exchange control boards and components by yourself. It may expose you to an
electrical shock or explosion, etc.
Caution
l
Motor overload protection is included in the default settings. Parameter 1-90
Motor thermal
protection
is set
to value
ETR trip.
l
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.
l
Never connect the AC main circuit power supply to the output terminals U.V W of the inverter.
l
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.
l
Installation, testing and maintenance must be performed by qualified professional personnel.
