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 Figure 1 on page 3

). Tightening torque is noted in the

illustration for reassembly.

2. Disconnect the DPI cable from the HIM assembly (if present) (see Figure

1 on page 3).

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 Figure 1 on page 3

). 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.
