2.8.1
Controller Input and Output
Connections
The
controller
provides
connections
for
two
programmable inputs and two programmable outputs.
See Figure 2-18 for the connector location and
Figure 2-19 for the I/O connection specifications.
Each input has a signal and a return connection. The
outputs are C form contacts with ratings of
500 mA @ 120 VAC. See Figure 2-20 for connections.
Use #12--24 AWG wire and tighten the connections to
0.5 Nm (4.4 in. lbs.).
For additional input and output connections, optional
input/output modules are available. See Section 4.3 for
instructions.

2.8.2
Harness Connection
Verify that the contactor harness is connected at the
controller base (or at the controller disconnect switch, if
equipped). See Figure 2-21.
Note:
Verify that the power is disconnected before
connecting or disconnecting the contactor
harness.
2.8.3
Controller Ground
Verify that the grounding wire is connected from the
controller’s lower left mounting stud to the enclosure.
This connection provides proper grounding that does
not rely upon the door hinges.
