WARNING

Disconnect power to the wall switch box by turning OFF the circuit

breaker or removing the fuse forthe circuit before installing the

RT12, replacing lamps, or doing any electrical work.

INSTALLATION& WIRING

1. Prepare the switch box.

After the power is turnedoff atthe circuitbreaker
box, removethe existingwall plateand mounting
screws. Pull the oldswitch outfrom thewall box.

2. Identify the type of circuit.

In a Single PoleCircuit (seeFig. 2), two single
wires connect totwo screwson theexisting
switch. A ground wiremay alsobe present
and connected to a groundterminal onthe old
switch. A neutral wireshould alsobe present
in the wall box.

CAUTION

For yoursafety: Connecting aproper ground to the time switch provides

protection against electricalshock inthe event of certain faultconditions.

If a proper groundis notavailable, consult with a qualified

electrician beforecontinuing installation.

Only connectthe RT12 to a Single Pole Circuit.The RT12is notsuitable for
3-way switching. If the existingwiring doesnot matchthe descriptionfor a
Single Pole Circuit,you shouldconsult with a qualified electrician.

3. Prepare the wires.

Tag thewires currently connected to theexisting switch
so that they can beidentified later. Disconnect thewires.
Make sure theinsulation isstripped offthe wires to expose
their copper coresto thelength indicated by
the “Strip Gage” in Fig. 3(approximately 1/2 inch).
