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.
