Installation Instructions

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.

If the adapter has address or data rate switches, and/or an Operating
Mode jumper, set them to appropriate positions. See the adapter User
Manual for complete details.

Mount the adapter.

PowerFlex 40 Class Frames B and C, and PowerFlex 400 Class Frame C

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

NOTE: For Frame B drives, the lower

left adapter screw does not ground the
adapter. To ground the adapter, install
the special drive cover onto the drive
using both cover fasteners.

C. With the adapter board right side up, remove its mounting screw from

the lower left hole. Save the screw for mounting in step F.

D. Connect the Internal Interface cable to the DSI port on the drive (see

Figure 3

E. With the adapter board oriented bottom side up, route the Internal

Interface cable under the adapter, and then to the mating DSI connector
on the adapter.

F. Install the adapter, bottom side up, to the right side of the display board

by snapping it into place. Then insert the adapter mounting screw into
the lower left hole on the board.

Important: Tighten the mounting screw in the adapter’s lower left hole

Connect one end of the network cable to the network. Make sure to use
the proper cable for the network. See the adapter User Manual’s “Related
Documentation” section for appropriate publication(s).

Route the other end of the network cable through the bottom of the
PowerFlex 40/400 Class drive, and connect the cable to the adapter using

the adapter’s mating socket or terminal block. For complete wiring details,
see the adapter User Manual.

Important: Make sure to properly route, wire, and ground the cable.

Always separate the communications wiring from the power
and motor wiring. For more information, see Wiring and
Grounding Guidelines for PWM AC Drives.

Read the adapter User Manual for information to configure and
determine how to apply the network to the host product.
