n

Only applies to air-cooled VFDs (i.e. ‘A’ Frame and ‘B’ Frame)

o

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).

p

Only applies to liquid-cooled VFDs (i.e. ‘C’ Frame)

q

A 4 year replacement interval applied to all 6-pulse and 18-pulse rectifier versions with previously available rectifier snubber capacitors. Snubber capacitors now
available extend the replacement period of “B” and “C” frames to 10 years (replacement period for “A” Frames remain at 4 years) – contact Cambridge for details and
to purchase extended life snubber capacitors. Active Front End rectifiers have a 10 year rectifier snubber capacitor replacement interval.

r

Replace UPS battery module yearly for 50°C rated VFDs.

s

When rectifier snubber capacitors are replaced, the MV connections for rectifier need to be inspected.

t

When inverter snubber capacitors are replaced, the MV connections for inverter need to be inspected.

u

These components may be serviced while the VFD is running.
