rotational speed is reduced, therefore, when the motor works in
overheating occasions, a strong exhaust fan should be retrofitted or
replace non-inverter motor with the inverter motor.
3) The inverter has built-in the adaptive motor standard
parameters, according to the actual situation, please identify motor
parameters or accordingly modify the default values to try to meet
the actual value, otherwise it will operation affect and protection
performance;
4) When short-circuit of cable or motor internal will activate the
inverter alarm, even bombing. Therefore, firstly perform insulation
short-circuit test for the initial installation of the motor and cable,
routine maintenance often also need to perform such test. Note that
the parts to be tested and the inverter shall be disconnected
completely when testing.

Others
1)We need to fix cover and lock before power on, so as to avoid the
harm to personal safety that is caused by internal injuries of bad
capacitors and other components.
2)Do not touch internal circuit board and any parts after powering
off and within five minutes after keyboard indicator lamp goes out,
you must use the instrument to confirm that internal capacitor has
been discharged fully, otherwise there is a danger of electric shock.
3)Body static electricity will seriously damage the internal MOS
field-effect transistors, etc., if there are not anti-static measures, do
not touch the printed circuit board and IGBT internal device with
hand, otherwise it may cause a malfunction.
4)The ground terminal of the inverter(E or
) shall be earthed
firmly according to the provisions of the National Electrical Safety
and other relevant standards. Do not shut down(power off) by
pulling switch, and only cut off the power until the motor stopping
operation.
5)It is required to add the optional input filter attachment so as to
meet CE standards.
1-4.Scope of applications
※
This inverter is suitable for three-phase AC asynchronous motor and permanent magnet
synchronous motor.
※
This inverter can only be used in those occasions recognized by this company, an
unapproved use may result in fire, electric shock, explosion and other accidents.
※
If the inverter is used in such equipment (e.g: equipment for lifting persons, aviation systems,
safety equipment, etc.) and its malfunction may result in personal injury or even death. In
this case, please consult the manufacturer for your application.
Only the well-trained personnel can be allowed to operate this unit, please carefully
read the instre1tions on safety, installation, operation and maintenance before use.
The safe operation of this unit depends on proper transport, installation, operation
and maintenance!
