Description
The GE-Emerson IC670GBI102 Field Control BIU Terminal Block is a bus interface unit that must be mounted on a 7.5mm x 35mm DIN rail that has a conductive (unpainted) finish for proper grounding. When using multiple rail sections, they must be properly aligned. The DIN rail should be mounted at least 4.25in from a wireway or other obstruction on the wiring side of the BIU, allowing for more space if I/O module wiring is very stiff.
The BIU has a metal grounding strip beneath the terminal block. This must be used with a grounded conductive DIN rail. It is not compatible with A versions of I/O Terminal Blocks, which do not have a metal grounding strip. Using the BIU with A version I/O blocks will result in a system with poor noise immunity.
For added vibration resistance, the DIN rail should be installed on a panel using screws spaced approximately 6in apart. For maximum vibration resistance, drill two holes for the BIU Terminal Block mounting ears as shown below. After mounting the terminal block on the DIN rail, install 3/8-inch (9.525mm) #6 screws (not supplied) through the mounting ears.
