Remote I/O Scanner 9
Publication 1747-IN060B-EN-P - June 2001
For New Installations
To ensure a proper earth ground of the cable shield, follow these steps:
1. While the RIO link connector is plugged into the scanner and lines 1 and 2
are connected, strip the cable back to expose enough shield drain wire to
reach a chassis mounting bracket.
2. Attach the ring terminal lug (supplied) to the end of the shield drain wire.
3. Attach the ring terminal lug to the SLC chassis mounting bracket. Note that
for new installations the middle (shield) terminal is not used when
connecting to the scanner.
IMPORTANT
The RIO cable shield must be grounded at the scanner end only.
