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.
For your safety: Connecting a proper ground to the sensor 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.
NOTE: Ground must be connected for proper functionality of the sensor.
Only connect the CS-50 to a Single Pole Circuit. The CS-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 Gauge," in Fig. 3
(approximately 1/2 inch).
4. Wire the sensor.
Twist the existing wires together with the wire leads on
the CS-50 sensor as indicated below. Cap them securely
using the wire nuts provided. See Fig 4.
• Connect the green or non-insulated (copper) GROUND
wire from the circuit to the green ground wire on the CS-
50. Make sure there is a solid ground connection.
• Connect the power wire from the circuit (HOT) to the
black wire on the CS-50.
• Connect the power wire to the lamp or fan (LOAD) to the
red wire on the CS-50.
5. Put the CS-50 in the wall box.
Position the lens above the ON/OFF button (lens at top,
button at bottom). Secure it to the wall box with the screws
provided.
6. Make any necessary adjustments.
See the SENSOR ADJUSTMENT section for information.
7. Attach the new cover plate.
8. Restore power to the circuit.
Turn on the breaker or replace the fuse. There is an initial warm-up period after installation in which it may take up to 1 minute
before the sensor will function
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 CS-50, REPLACING LAMPS, OR DOING ANY ELECTRICAL WORK.
