Warning
Hazardous voltage or energy may be present on DC power terminals.  Always replace cover when 
terminals are not in service.  Be sure uninsulated conductors are not accessible when cover is in 
place. 
Statement 1075
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:
Step 1
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.
Step 2
Strip 1/2” of insulation off the DC wires you will use.
Step 3
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.
Step 4
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.
