If the series inverter is used outside the allowable working voltage range as specifed in this manual, it
is easy to damage the devices in the inverter. When necessary, use the corresponding step-up or
step-down instruments to change the voltage .

The series inverter has lightning over current protection device, and has certain self-protection
capacity against the lightning. In applications where lightning occurs fre quently, the user shall
install additional protection devices at the front-end of the inverter.

In areas with altitude of more than 1,000 meters, the heat sinking effect of the inverter may
turn poorer due to rare air. Therefore, it needs to derate the inverter for use. Please contact our
company for technical consulting in case of such condition.

1) The standard adaptable motor is four-pole squirrel-cage asynchronous induction motor. If
such motor is not available, be sure to select adaptable motors in according to the rated
current of the motor. In applications where drive permanent magnetic synchronous motor is
required, please consult our company;
2) The cooling fan and the rotor shaft of he non-variable-frequency motor adopt coaxial
connection. When the rotating speed is reduced, the cooling effect will be poorer. Therefore, a
powerful exhaust fan shall be installed, or the motor shall be replaced with variable-frequency
motor to avoid the over heat of the motor.
3) Since the inverter has built-in standard parameters of the adaptable motors, it is necessary
to perform motor parameter identification or modify the default values so as to comply with
the actual values as much as possible, or it may affect the running effect and protection
performance;
4)The short circuit of the cable or motor may cause alarm or explosion of the inverter.
Therefore, please conduct insulation and short circuit test on the newly installed motor and
cable. Such test shall also be conducted during routine maintenance. Please note that the
inverter and the test part shall be completely disconnected during the test.
