LEGRAND Wattstopper FSP-321 Instructions D'installation page 2

INSTALLATION
1. Determine an appropriate mounting location inside the light
fixture minimizing the electric light contribution to the sensor's
photocell. Allow a minimum distance of 0.2" (5.1mm) from the
wiring end of the sensor to the wall of the fixture.
2. Drill a hole 1.30" (33.0mm) in diameter through the sheet
metal in the bottom of the fixture.
3. Add the rubber gasket to the threaded collar, and install the
sensor face down, parallel to the mounting surface. Ensure
the rubber gasket touches the inside surface of the fixture.
Install the nut (or optional collar) securely against the fixture
to a torque of 25–30 in-lbs to ensure Ithe lens is installed
properly.
4. Align the locking features between the sensor and lens
module and push the lens module forward until the o-ring
seals firmly. Turn the lens module clockwise to ensure it locks
in place.
5. Connect wires as shown in wiring diagram.
6. Restore power from the circuit breaker.
NOTE: An optional collar can be installed in place of the tightening
nut. See the Ordering Information table on page 4 for details.
Several lenses are available for use with the FSP-321. Lenses give coverage at mounting heights between 8' – 40' for applications such
as offices, warehouses, and outdoor use. Density and range of the coverage is determined by the type of lens and mounting height.
A lens with shroud option is also available. The shroud blocks light coming from the fixture, to prevent interference with the photocell
function of the sensor. Lens modules are IP-66 rated when combined with an FSP-321 sensor mounted to an outdoor-rated fixture. See
the FSP-Lx Lens Coverage Guide for more information.
