Step 1: Remove Power
from the Drive
1. Remove and lock-out all incoming power to the drive.
Step 2: Open the Control
Panel 1. Disconnect the DPI cable from the HIM (if present).
2. Insert a flathead screwdriver into the holes in the right side of the protective
covers on the drive and turn the latch 90° counter-clockwise.
3. Open the control panel to the left.
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.
