Step 1: Remove Power
from the Drive
1. Remove and lock-out all incoming power to the drive.
Step 2: Remove the
Protective Covers
1. Loosen, but do not remove, the four hexalobular screws that secure the top
control pan cover to the drive, then slide the cover up and off the drive
chassis (see
). Tightening torque is noted in the
illustration for reassembly.
2. Disconnect the DPI cable from the HIM assembly (if present) (see
Important: A communication cable is connected to the back of the HIM
assembly and to the Control board mounted on the control pan.
Therefore, the bottom control pan cover and HIM assembly
cannot be fully removed from the drive until the cable is
disconnected. Step 4 details this connection.
3. Loosen, but do not remove, the four hexalobular screws that secure the
bottom control pan cover to the drive, then slide the cover up and off the
drive chassis (see
). Tightening torque is noted in the
illustration for reassembly.
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.
