Before installing a DC power supply to the switch, you will need to attach DC connection wires that you
provide (10 GA recommended) to the DC power connector included in the DC power supply’s accessory
kit. To wire the connector:
Step1 Using a 1/8” flat head screwdriver or No. 1 Phillips head screwdriver, loosen the set screws on the
connector to freely accept the power wires. The connector will accept 8-24 AWG wires, use what your
local electrical code calls for.
Step2 Strip 1/2” of insulation off the DC wires you will use.
Step3 Insert the black (DC negative) wire into the right aperture on the connector and tighten down the
connection set screw. Finger tight or about 3 ft./lbs should be sufficient.
Step4 Insert the red (DC positive) wire into the left aperture on the connector and tighten down the connection
set screw. Do not tighten over 0.7 Nm.
