INSTALLATION & WIRING
Disconnect power to the wall switch box by turning OFF the circuit
breaker or removing the fuse for the circuit before installing the
RT-50, replacing lamps, or doing any electrical work.
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. 1), 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.
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
Only connect the RT-50 to a Single Pole Circuit. The RT-50 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. 2 (approximately 1/2 inch).
4. Wire the time switch.
Twist the existing wires together with the wire leads on the time switch as
indicated in the drawing. Cap them securely using the wire nuts provided. See
Fig 3.
• Connect the green or
non-insulated (copper)
GROUND wire from the
circuit to the GROUND
terminal on the RT-50.
• Connect the power wire
from the circuit (HOT)
to the black wire on the
RT-50.
• Connect the power wire
to the lamp or fan (LOAD)
to the red wire on the
RT-50.
• Connect the NEUTRAL
wires from the circuit
to the white wire on the
RT-50.
5. Put the RT-50 in
the wall box with
the time selection
buttons positioned
above the ON/OFF
button.
Secure it to the wall box with
the screws provided.
6. Install cover plates.
Install industry standard decorator wall switch cover plate (not included).
7. Restore power to the circuit.
Turn on the breaker or replace the fuse.
