KE600 Inverter Safety and Precautions
5
1.2.12 Certain Special Use
If the user needs to use the inverter with the methods other than the recommended wiring diagram in this
manual, such as shared DC bus, please consult our company.
1.2.13 Note of Inverter Disposal
The electrolytic capacitors on the main circuit and the PCB may explode when they are burnt. Emission of
toxic gas may be generated when the plastic parts are burnt. Please dispose the inverter as industrial
wastes.
1.2.14 Adaptable Motor
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 the non-variable-frequency motor adopt coaxial connection. When
the rotating speed is reduced, the cooling effect will be poorer. Therefore, a powerful exhaust fan should be
installed, or the motor should 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 should also be
conducted during routine maintenance. Please note that the inverter and the test part should be completely
disconnected during the test.
