2 PowerFlex® DC Drive Communication Interface Cable

Step 1: Remove Power

from the Drive

1. Remove and lock-out all incoming power to the drive.

Step 2: Remove the

Protective Covers and the

Existing Communication

Interface Cable

1. Disconnect the DPI cable from the HIM (if present).

2. For frame A drives only, remove the screws that secure the bottom

protective cover to the drive, then slide the cover down and off the drive

chassis. For frame B and C drives, refer to step 3b. on page 4

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.
