Connections and Wiring

*

1. Remove and save the AUTO-MANUAL-OFF
jumper.

2. Wire the input(s) common ground to “GND” of
the INPUT terminal block.

3. Wire the individual (6–40 VDC or 24 VAC)
input(s) to the appropriate terminal(s) of the
INPUT block.

*NOTE: Puingthejumperintothe“MANUAL”

position turns on the triac relay (when no
triggering voltage is present on the input).
If “MANUAL” mode is to be used, wire
power (+ 6–40 VDC or 24 VAC) to the
“POWER” terminal of the INPUT terminal
block. This must have the same reference
(–) ground as the inputs.

4. Wire the individual output(s) to the appropriate
terminals of the OUTPUT terminal block.

NOTE: Triacs are for switching AC only. Output

rating is up to 5 A at 280 VAC. See the data

sheetforadditionalspecications.

5. The triac output must be in series with the load
and transformer output.

*NOTE: The jack on the board for a plug-in

transformer was discontinued on units built
after May 2013. Connect auxiliary (manual
override) power to the Power and Ground
terminals instead. If an older unit that uses
a plug-in transformer is being replaced,
