Adding Common Mode Chokes
(1
st
Gen GP4 Classic Compressor
Only)
Common mode chokes are necessary to maintain
protection against bearing currents causing pre-mature
failure of the compressor bearings. With the removal of
the output inductor, common mode chokes are necessary.
The choke assembly encircles all current carrying
conductors between the drive and compressor (meaning
do not include ground conductors). Individual cores must
also be installed on the power conductors. Refer to the
schematic and image below. With removal of the output
inductor, the power conductors will be need to be spliced
together. Polaris electrical connectors are recommended
(Catalog No.: IT-250). Six (6) pieces are needed. There are
two conductors per phase.
