1. Remove and lock-out all incoming power to the drive.

ATTENTION: Remove power before making or breaking cable

connections. When you remove or insert a cable connector with

power applied, an electrical arc may occur. An electrical arc can

cause personal injury or property damage by:

• sending an erroneous signal to your system’s field devices,

causing unintended machine motion

• causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the

module and its mating connector. Worn contacts may create

electrical resistance.
