Insulating Material Intelligen Inverter FR-A820-2.2K-1 For Transition Current

Product Details

Note:
In order to prevent electric shock, the motor and frequency converter must be
grounded before use.

• Do not install the incoming capacitor or surge suppressor, radio noise filter
to the output of the frequency converter. This will lead to the failure of the
frequency converter or the damage of the capacitor and surge suppressor. If any
of the above equipment has been installed, please remove it immediately. When
it is necessary to set a non fuse circuit breaker at the output end, please
consult the manufacturer for the selection of non fuse circuit breaker.

• With regard to electromagnetic wave interference, the input / output (main
circuit) of the frequency converter contains high-frequency components, which
may interfere with the communication equipment near the frequency converter
(such as AM radio). Therefore, EMC filters are installed to minimize
interference.

• For details of peripheral devices, please refer to the user manual of each
option and peripheral device.

• PM motor cannot operate on power frequency power supply.

• Because PM motor is a motor with built-in permanent magnet, even when the
power supply of frequency converter is disconnected, as long as the motor is
still rotating, high voltage will be generated at the motor terminal. When the
output switch is closed, turn on the power supply of the frequency converter
and use it when the motor is stopped.
