Regen Wiring (AC drives)
For complete instructions pertaining to an external regen resistor with an AC input drive, refer to
the System Wiring Diagrams. In addition to the information in that section, users installing
drives for use in a CE installation should use an appropriately-grounded, shielded regen cable
to reduce overall system emissions.

ESISTOR
When using an external regen resistor, if regen cabling is
accessible during normal machine operation, the cable
should be a shielded cable rated at 450 VDC with the shield
CAUTION
connected to PE.
When using a regen resistor in a CE installation, the cable
should be appropriately rated and have a braided shield
connected to PE for safety, and clamped to the ground
