Motor Power Cable Shield Termination

Factory-supplied motor power cables for MP-series motors are shielded, and the
braided cable shield must terminate at the drive when installed. A small portion
of the cable jacket must be removed to expose the shield braid. The exposed area
must be clamped (using the clamp provided on the 2099-BM06-S, -BM07-S and
-BM08-S drives) to the drive to provide a 360° termination. Factory-supplied
power cables must also be terminated in the motor power (MP) connector plug.

Customer-supplied power cables must be shielded, and the braided cable shield
or conduit must terminate at the drive when installed. An area of the power cable
shield must be exposed and terminated for 360° at the drive. In a similar manner,
conduit enclosing discrete power cables must be terminated for 360° at the drive.

ATTENTION: To avoid hazard of electrical shock, be sure the shielded power
cables are grounded at a minimum of one point for safety.
