The power/controller carriers and 8-wide I/O interface carriers install on standard 35 mm (1.38 in.) T-type rails. Use the heavier (15mm-deep) T-type rails because they better accommodate the weight distribution of DeltaV equipment. The carrier shield bar provides a connection point for field shield wires for the I/O interface carrier.
CAUTION!The DeltaV I/O Cards and Controller must be installed vertically on the horizontal carrier for cooling purposes.
