※
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.
when the 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.
1) Never connect the AC power to the inverter output
terminals(U, V, W).
2) Properly fix and lock the panel before powering on, so as
to avoid hurting the personal safety due to internal poor
capacitors.
3) Never perform wiring, checking and other operations after
power is turned on.
4) Do not touch the internal circuit board and its components
in order to avoid the risk of electric shock after this unit is
powered,
5) 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.
6) 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.
7)The ground terminal of the inverter(E or
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.
8) It is required to add the optional input filter attachment so
as to meet CE standards
