Input RFI Filters
Filter Wiring - 1305
6. Connect remaining wires. Cables must use knockouts defined in
the figure below.
7. To assure that the RFI filter is effective and to reduce cable radia-
tion, the motor cable must be shielded or armored. The ground
conductor of the motor cable (drive end) must be connected
directly to the drive ground terminal, not to the enclosure bus bar.
The shield must be bonded to the metal where the motor cable
exits the drive. At the motor end, the ground conductor should
also be connected to the motor case ground. The shield or armor
must be bonded to the filter (and drive). At the motor end, the
shield should also be connected to the motor case ground.

!
ATTENTION: To guard against possible equipment
damage, RFI filters can only be used with AC supplies that
are nominally balanced with respect to ground. In some
installations, three-phase supplies are occasionally
connected in a 3-wire configuration with one phase
grounded (Grounded Delta). The filter must not be used in
Grounded Delta supplies.
