Before installing a DC power supply to the fabric interconnect, you must attach DC connection wires that
you provide (10 GA recommended) to the DC power connector included in the DC power supply's accessory
kit.
Procedure
Step 1
Using a 1/8-inch 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 requires.
Step 2
Strip 1/2-inch 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 0.51 ft./lbs.
