Installation Instructions

PowerFlex 7-Class DPI (Drive Peripheral Interface)
Network Communication Adapter

This document explains how to install and wire a PowerFlex 7-Class Network
Communication Adapter into a PowerFlex 7-Class drive.

ATTENTION: Risk of injury or death exists. The PowerFlex 7-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 not being installed in a PowerFlex 7-Class drive, refer to the
instructions for the host product (DPI External Comms Kit, SMC Flex Smart Motor
Controller, PowerFlex 7000 drive, PowerFlex DC drive, etc.) before/when installing
the adapter.

Secure and ground the adapter to the drive by doing the following:

• On a PowerFlex 70 drive, fold the Internal Interface cable behind the

adapter and mount the adapter on the drive using the four captive
screws. Use the torque recommended in the drawing.

• On a PowerFlex 700, PowerFlex 700H drive or PowerFlex 700S drive,

mount the adapter on the drive using the four captive screws. Use the
torque recommended in the drawing.

Ground Tab Detail

Verify metal ground tab is bent 90°
and is under the adapter before
tightening screw. After tightening
the screw, verify continuity exists
between the head of the screw
and drive ground.

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 to the outside of the 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.
