WEG Frequency Inverter - CFW-09 500-600 V CFW-09 500-600 V

It is recommended to replace the blowers after each 40.000 hours of operation.

If the inverter is stored for long periods, we recommend to power it up once a year during 1 hour. For 220-230 V and 380-480 V models apply supply voltage of approximately 220 Vac, three-phase or single-phase input, 50 or 60 Hz, without connecting motor at output. After this energization, wait 24 hours before installing it. For 500-600 V, 500-690 V and 660-690 V models use the same procedure applying a voltage between 300 V and 330 Vac to the inverter input.

It is recommended to replace DC Bus Capacitors after five years of operation.

Check the DC Bus Capacitors every six months
