What You Need to Do

To install the field SCR module:

❐ Step 1: Remove power from the drive

❐ Step 2: Remove the protective covers

❐ Step 3: Remove the field board

❐ Step 4: Remove the existing field SCR module

❐ Step 5: Install the new field SCR module

❐ Step 6: Install the field board

❐ Step 7: Replace the protective covers and document the change

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).

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.
