Wiring
Power
The switch can be powered from the same DC source that is used to power your other devices. To
maintain the UL listing, this must be an SELV (Safety Extra Low Voltage) power supply. A DC voltage
in the range of 12 to 48VDC needs to be applied between the P1+ terminal and the P1- terminal
as shown below. The chassis screw terminal should be tied to panel or chassis ground. To reduce
down time resulting from power loss, the switch can be powered redundantly with a second
power supply as shown below. A recommended DC power supply is AutomationDirect.com part
number PSL-24-010.
Terminal block connector is Degson 2EDGK-5.08-04P-14-1000AH or equivalent.
Ferrule required for stranded wire.
Wire Size Range: 24 – 12 AWG
Wire Strip Length: 7mm
Maximum terminal screw torque is
4.43 lb-in (0.5 N·m).
