TERMINAL BLOCK INSTRUCTION FOR THE
CONNECTION OF HIGH/LOW VOLTAGE WIRES

When connecting line and/or low voltage wires to
the CAH terminal block(s) a 3/32-screw driver
(thermostat type) is required.

1. Insert the screwdriver into the square hole until

you “hit bottom.” This will open the terminal
block so that it will accept your wire(s).

2. Insert the stripped wire into the oval or round

hole.

3. Remove screwdriver to allow the terminal block

to “clamp down” on the wire(s).

IT IS EXTREMELY IMPORTANT THAT THE WIRE(S)
ARE CONNECTED PROPERLY OTHERWISE ARCING
MAY RESULT IN ELECTRICAL DAMAGE OR FIRE!
