INSTALLATION & WIRING
1. Prepare the switch box.
After the power is turned OFF at the circuit
breaker box, remove the existing wall plate and
mounting screws. Pull the old switch out from the
wall box.
2. Identify the type of circuit.
In a Single Pole Circuit (see Fig. 2), two single
wires connect to two screws on the existing
switch. A ground wire may also be present and
connected to a ground terminal on the old switch.
A neutral wire should also be present in the
wall box.
CAUTION
For your safety:
Connecting a proper ground to the time switch provides
protection against electrical shock in the event of certain fault conditions.
If a proper ground is not available, consult with a qualified
electrician before continuing installation.
Only connect the RT1 to a Single Pole Circuit.
The RT1 is not suitable for
3-way switching. If the existing wiring does not match the description for a
Single Pole Circuit, you should consult with a qualified electrician.
3. Prepare the wires.
Tag the wires currently connected to the existing switch,
so that they can be identified later. Disconnect the wires.
Make sure the insulation is stripped off the wires to
expose their copper cores to the length indicated by the
“Strip Gage” in Fig. 3 (approximately 1/2 inch).

WARNING
Disconnect power to the wall switch box by turning OFF the circuit
breaker or removing the fuse for the circuit before installing the
RT1, replacing lamps, or doing any electrical work.
