Step 1: Remove Power
from the Drive
• Remove and lock-out all incoming power to the drive.
Step 2: Remove the
Protective Cover and Open
the Control Panel 1. Loosen, but do not remove, the six hexalobular screws that secure the
bottom protective cover to the drive, then slide the cover down and off the
drive chassis. Tightening torque for reassembly is noted in the illustration
below.
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.
