Notes:
1. Terminal numbers are shown on each connector. The plug-in portions of the connectors are packed with a case.
The connectors are keyed.
2. Case/Safety Ground - Connect to green screw at top center of rear terminal area.
3. NCA and NCB - Connect Modbus cable or twisted pair wiring. Refer to UM353-1B, Section 7.4.9 for
additional details.
4. IOA and IOB - No connection
5. Ground Bus - An external, user-supplied ground bus can ease connection of multiple grounds, particularly when
twinaxial cable shields are to be grounded.
6. Terminals 6, 9, 18, 21, 24, 34, 40, and 42 are electrically connected. Use the terminals that allow the best wire
routing and the least stress on components, such as range resistors.
