The power/controller carriers and 8-wide I/O interface carriers install on standard 35 mm (1.38 in.) T- or G-type DIN rails. If you use T-type rails, use the heavier (15mm-deep) rails because they better accommodate the weight distribution of DeltaV equipment. The optional carrier shield bar provides a connection point for field shield wires for the I/O interface carrier. You cannot connect a vertical carrier to a horizontal carrier or a horizontal carrier to a vertical carrier. You must choose one carrier configuration. Refer to Appendix M DeltaV Vertical Carriers for information on installing vertical DIN rails and carriers.
CAUTION!The DeltaV I/O Cards and Controller must be installed vertically on the horizontal carrier for cooling purposes.
