LEGRAND Wattstopper FSP-212D Instructions D'installation page 2

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.
There are two mounting methods for the FSP-212D—using the threaded collar or using the snap-in tabs.
Threaded Collar Mounting
1. Drill a hole 1.30" (33.0mm) in diameter through the sheet metal in
the bottom of the fixture.
NOTE: The Outside Fixture Wall thickness should be no greater
than 0.125" (3.18mm) for optimal sensor mounting and
security.
2. 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 plastic
nut (or optional collar) securely against the fixture to a torque of
25-30 in-lbs to ensure IP rating is maintained.
3. Align the locking features between the sensor and lens module
assembly and push the lens module forward until the o-ring seals
firmly. Turn the lens module clockwise to ensure it locks in place.
4. Connect wires as shown in wiring diagram.
5. 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 5 for details.
Snap-In Mounting
1. Cut a rectangular hole 32.6mm (± 0.2mm) by 89.9mm (± 0.2mm)
through the sheet metal in the bottom of the fixture. The surface of
the bottom of the fixture must be between .75mm and 3.2mm.
2. Push the FSP-212D up from below the fixture until the tabs "snap"
and the fixture locks in place.
3. Align the locking features between the sensor and lens module
assembly and push the lens module forward until the o-ring seals
firmly. Turn the lens module clockwise to ensure it locks in place.
4. Connect wires as shown in wiring diagram.
5. Restore power from the circuit breaker.
NOTE: Snap-in mounting is not rated for IP66.
