Make sure the power source is OFF prior to connecting the timer. 1. Route the power and equipment ground wires from the power source, through the conduit and into the timer transformer compartment. Note: The timer terminal block accepts wire size up to 14 gauge. 2. Remove 3/8" insulation from the wire ends. 3. Using a small flat blade screwdriver, secure the wires as shown to the terminal block as follows: Line or Line 1 (L1) to L, Neutral or Line 2 (L2) to N and Equipment Ground to . 4.
