Special use
If the user need to use methods other than the suggested wiring
diagram provided in this manual, such as common DC bus, please
consult our technician.

Precautions for
scrap disposal of the
inverter
It may explode when electrolytic capacitors on the main circuit
and printed circuit board are burned. When burning plastic parts,
it may produce toxic gases.Please disposing as industrial waste.

About
adaptive motor
1) Standard adaptive motor shall be four-pole asynchronous
squirrel-cage induction motor. Apart from the said motors, please
select the inverter according to the motor rated current.
2) The cooling fan and the rotor shaft for non-inverter motor are
coaxially connected, the fan cooling effect is reduced 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.

Others
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
)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.
8) It is required to add the optional input filter attachment so as to
meet CE standards
