Notes:
1. Use this table for both direct entry (green or gray connectors) and side entry (black connectors) terminal styles.
2. # - Terminal letters and numbers are printed on individual connectors. Model 353_1_N… has 2 connectors;
Model 353_2_1… has 4 connectors and an I/O Expander board. (Underscore is a placeholder/wildcard; ellipsis
indicates that subsequent characters do not affect selection.)
3. Safety/Case Ground - Wire to green screw at top center of rear terminal area.
4. NCA and NCB - Connect LIL Twinaxial Cable or twisted pair wiring. Refer to Section 8.5 for additional
information.
5. IOA and IOB - LonWorks bus connections. Twisted pair wiring is typical.
6. Ground Bus - An external, user-supplied ground bus can ease connection of multiple grounds, particularly
when twinaxial cable shields are to be grounded.
