TERMINAL STRIP CONNECTIONS
INSTALLATION
The terminal strip connections are designed to clamp down on the
incoming building power and thermostat wiring connections. To
properly connect the wires to the terminal strip:
1. Push a small flat head screwdriver into the square hole on
the terminal. Press firmly until the screwdriver hits the
back stop and opens the terminal. See Fig. 45.
2. Remove approximately 3/8 in. (9.5 mm)of insulation from
the end of the wire and push the stripped wire into the oval
hole in the terminal.
3. Remove the screwdriver. Pull on the wire to make sure
that it is securely clamped in the terminal.
4. Make sure that the terminal clamp is in contact with bare
wire (insulation removed).
