Installing the FOUNDATION Fieldbus H1 Interface,
CI852/TP852
The CI852 is powered from the processor unit via the CEX-bus and requires
therefore no additional external power source. No field device on the FF H1 bus is
powered from the CI852.
An AC 800M Controller connected to a CI852 constitutes a FOUNDATION
Fieldbus linking device.
Use the following procedure to install the CI852/TP852:
1. Mount the unit onto the DIN-rail, see Mounting AC 800M Units onto DIN-Rail
on page 49 and Installing the PM8xx/TP830 Processor Unit in Single
Configuration on page 56.
2. Install a connector on the FOUNDATION Fieldbus cable. Connect the cable
screen to the ground terminal within the connector to ground the screen via
CI582.
3. Connect the FOUNDATION Fieldbus cable to the contact on the baseplate.
FOUNDATION Fieldbus H1 Connection
Connect the FF H1 bus to the male DB9 connector located on the TP852 Baseplate.
The use of shielded twisted pair cables for FOUNDATION Fieldbus is
recommended (see Appendix C, Recommended Components).
