TEC0296R1

NOTE: The TEC Actuator Package is shipped with the actuator (and optional Autozero Module, if there

is one) pre-wired to the TEC’s terminal block. This terminal block must be removed so that the cable

assembly’s terminal block can be plugged into the TEC (as shown above). The wires from the actuator

(and optional Autozero Module) must be removed from the original TEC terminal block and inserted into

the cable assembly’s terminal block as illustrated. Also, the associated cable assembly wires (shown as

dashed lines) SHOULD BE REMOVED. This will ensure that disruptive signals cannot travel from the

relay module back through the cable assembly and corrupt the TEC’s control signals.

7. Unplug the terminal block from the controller.

8. Using the cable assembly, connect the relay

module to the controller as shown in Figures 4,

5, or 6. Make sure the connections are secure.

9. Wire up the terminal block, wiring switched DOs

per the example in Figure 1. (See Table 1 to

determine which DOs are switched.) Wire

unswitched DOs normally.
