Installing the Ground Point
Overview The cable system should be grounded at a point within 20 ft of the RIO processor at
the head-end of the network. A Modicon 60-0545-000 Ground Block, a single
Modicon MA-0185-100 Tap, a Modicon MA-0186-100 Splitter, or a Modicon MA-
0331-000 Splitter may be used, assuring that the cable system will be permanently
grounded even when disconnected from the RIO processor.
A screw is provided on taps, splitters, and ground blocks as the grounding point. If
you use a ground block, mount it in a small enclosure.
To install a 60-0545-000 Ground Block:
z Cut the cable
z Install two F connectors on the cable
z Attach two F connectors to the ground block
z Wire the ground block to an appropriate ground (typically building steel)
Note: Do not disconnect the cable system from the central ground point—
disconnecting the system from ground will create an unfavorable floating ground
condition.
