Interface Connections
All other control interface connections are made at a twelve-pole
connector located on the top of the module. Refer to Figure 3.5 and
Table 3.B for connections (and Table 1.A for electrical ratings).
Refer to the
Wiring Guidelines section in this chapter for guidance in
making connections to the control circuit.

Refer to Table 1.A for electrical ratings.
No connection required if option is not used.
Ensure compatibility of IntelliVAC input ratings with those of circuit components activating these inputs. Consider means of
isolating/loading these signals, as required (using interposing relays or load resistors). Consult factory for assistance, if needed. The
Series C and D IntelliVACs are compatible with most PLC outputs, and have been verified with Rockwell Automation OA type 120V
triac outputs. See Wiring Guidelines.
For electrically held contactor, this command will energize the close coil output (CCO).
For mechanically held contactor, this command will energize the trip coil output (TCO).
