Installing the Adapter

This chapter provides instructions for installing the adapter in a PowerFlex

7-Class drive.

Preparing for an Installation

Before installing the adapter, verify that you have all required equipment.

See Required Equipment

on page 1-3.

Selecting Remote I/O Cables

Remote I/O adapters are connected to the Remote I/O network or link with

twinaxial cable used for Remote I/O and Data Highway Plus (DH+)

communications. When selecting a cable, remember these points:

• Only 1770-CD Belden #9463 is tested and approved for Remote I/O and

DH+ installations. Use other cables at your own risk.

• The maximum cable length depends on the baud rate.

• All three connectors (blue, shield, and clear) must be connected at each

node.

• Do not use a star topology. Only two cables may be connected at any

wiring point. You can use a series topology and daisy-chain two wires at

a point.
