(1) These components may be serviced while the VFD is running.
(2) 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).
(3) When rectifier snubber capacitors are replaced, the MV connections for the rectifier need to be inspected.
(4) A 4-year rectifier snubber capacitor replacement interval applied only to drives with 18-pulse rectifiers shipped before 2012 (rectifier snubber capacitors are blue). However, current enhanced replacement
rectifier snubber capacitors extend this to a 10-year replacement interval (replacement rectifier snubber capacitors are black). A 10-year rectifier snubber capacitor replacement interval has always
applied to drives with AFE rectifiers.
(5) When inverter snubber capacitors are replaced, the MV connections for the inverter need to be inspected.
(6) A 10-year inverter snubber capacitor replacement interval applies to all drive configurations.
(7) Replace UPS batteries annually for 50°C rated VFDs.
