When a contactor is installed between the output side of the AC drive and the
motor, do not turn off the contactor when the AC drive is active. Otherwise,
modules inside the AC drive may be damaged.
1.2.8 Applied with the Rated Voltage
Apply with the rated voltage. Failure to comply will damage inverter. If
required, take a transformer to boost or step-down voltage.

1.2.9 Do Not Apply a 3-Phase Input Inverter to 2-Phase Input Applications
Do not apply a 3-phase input FR inverter to 2-phase input applications. Otherwise,
it will result in faults or damage inverter.
1.2.10 Lightning Protection
The product
certain self-protection capacity against the lightning. Additional protection devices
have to be installed between inverter and power supply in the area where lightning
occurs frequently. has integrated lightning over-current protection device which has
1.2.11 Altitude De-rating
In places where the altitude is above 1000 m and the cooling effect reduces due
to thin air, it is necessary to de-rate the AC drive. Contact Our company for
technical support.
1.2.12 Adaptable Motor
Standard adaptive motor is quadrupole squirrel- cage asynchronous induction
motor. If it is not above- mentioned motor, please select AC drive upon rated
current of moter. If you need to drive permanent magnet synchronous motor,
please consult our company;
The cooling fan of non variable frequency motor and rotor spindle are coaxially
connected. While despinning, the fan cooling effect also declines at the same
time.Hence, for overheated occasion of moter, you shall install strong exhaust
fan or change variable frequency motor;
AC drives have built- in adaptive motor standard parameters. It is necessary to
make motor parameter identification or amend default values to accord with
actual values, or it will influence operation effects and protective values;
As short circuit existing inside cable or motor will cause inverter alarming,
enen explosion. Therefore, please make insulation short- circuit test of initial
installed motor and cable first. And the test also is necessary in routine
maintenance.
