PowerFlex 4-Class DSI (Drive Serial Interface)
Network Communication Adapter

This document explains how to install and wire a PowerFlex 4-Class Network
Communication Adapter into a PowerFlex 40 Class or PowerFlex 400 Class drive.

ATTENTION: Risk of injury or death exists. The PowerFlex 40/400
Class drive may contain high voltages that can cause injury or death.

!

Remove power from the drive, and then verify power has been discharged
before removing the drive cover.

ATTENTION: Risk of equipment damage exists. The Network
Communication Adapter contains ESD (Electrostatic Discharge) sensitive

!

parts that can be damaged if you do not follow ESD control procedures.
Static control precautions are required when handling the card. If you are
unfamiliar with static control procedures, refer to Guarding Against
Electrostatic Damage, publication 8000-4.5.2.

If the adapter is being installed in a DSI External Comms Kit, refer to its Installation
Instructions, publication 22-COMM-IN001 before/when installing the adapter. See
“Related Documentation” for details.

A. Mount the adapter on the required special drive cover (see Figure 1 for

part numbers).

– Frame C: Use the adapter screw to secure the adapter to the cover.

Important: Tighten the adapter’s lower left screw to properly

ground the adapter (see Figure 1).

– Frame B: Disregard the screw and snap the adapter in place.

Important: Install the drive cover onto the drive using both cover

fasteners to properly ground the adapter.

B. Connect one end of the Internal Interface cable to the DSI port on the

drive and the other end to the mating DSI connector on the adapter
(Figure 2
