Step 1: Remove Power
from the Drive

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.
