Only applies to air-cooled VFDs (i.e. ‘A’ Frame and ‘B’ Frame)
If filter supplied is not a washable type, replace filter. If filter supplied is a washable type, wash or replace (depending on state of filter).
Only applies to liquid-cooled VFDs (i.e. ‘C’ Frame)
A 4-year replacement interval applies to 6-pulse or 18-pulse versions. Active Front End rectifiers have a 10-year rectifier snubber capacitor replacement interval.
Replace UPS batteries yearly for 50°C rated VFDs.
When rectifier snubber capacitors are replaced, the MV connections for rectifier need to be inspected.
When inverter snubber capacitors are replaced, the MV connections for inverter need to be inspected.
These components may be serviced while the VFD is running.
