Important Notes
Please read before installing.
1. A ground connection is required for product to function.
®
Connect green-sleeved wire to ground only in retrofit and
replacement applications. When neutral connection is
available, remove green sleeve and connect to neutral. If
neither wire is present, consult a licensed electrician.
2. Device will not function if black wire and red wire
(Circuit 1/Line 1) are not wired.
3. This product is rated to control 6 A per circuit. Circuits may
NOT be wired in parallel to control loads greater than 6 A.
4. When power is applied, the sensor switch can be manually
turned on or off after the first 10 seconds and will
automatically control the load after 2 minutes.
5. CAUTION: Risk of Electric Shock — More than one
disconnect switch may be required to de-energize the
equipment before installing the unit, rewiring, or replacing
bulbs.
6. The sensor switch requires an unobstructed view of the room
and line-of-sight to detect motion.
7. Hot objects or moving air currents can affect the performance
of the sensor switch and may cause the sensor to turn
on unexpectedly or maintain its current state longer than
desired.
8. CAUTION: To reduce the risk of overheating and possible
damage to other equipment,
DO NOT use to control receptacles.
9. Install in accordance with all national and local electrical
codes.
10. For indoor use only. Operate between 32 °F and 104 °F
(0 °C and 40 °C).
11. Clean with a soft damp cloth only. DO NOT use any chemical
cleaners.
