Rockwell Automation 1771-CFM,D17716.5.99 CONFIGURABLE FLOWMET - Manual (Page 26)

2–8 Install the CFM Module
Publication 1771Ć6.5.99 - December 1995
Connect your I/O devices to the 40-terminal field wiring arm
(cat. no. 1771-WN) shipped with the CFM module. Use the wiring
examples on pages 2–9 and 2–10 for additional assistance on
connecting your devices.
!
ATTENTION: Remove power to all I/O devices
before you connect them to the wiring arm. Failure to
remove power from your I/O devices could cause:
•
injury
•
damage to module circuitry
•
equipment damage due to unexpected operation
(See applicable codes and laws.)

The sensor cable must be shielded. The shield:
• must extend the length of the cable, but be connected only at the
1771 I/O chassis
• must extend up to the point of termination
Important: The shield should extend to the termination point,
exposing just enough cable to adequately terminate the
inner conductors. Use heat shrink or another suitable
insulation where the wire exits the cable jacket.
