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: Installation shall be in accordance with all applicable regulations, local and NEC
codes.
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.
• Connect the power wire from circuit Neutral (White)
to Signal Wire (Blue wire with White stripe) on the
CS-50.
NOTE: In cases of retrofit or replacement where
no neutral is present, connect signal wire to
ground.
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.
