NOTICE: Improper installation can result in
degraded wireless communication and/or
intermittent or sustained communication failures,
and will not be covered under warranty.
Purpose of Document
This document is intended to help OEMs integrate Lutron PowPak fixture control modules and sensors into their
fixtures and provide guidance on how to achieve optimum performance from their Lutron controlled equipment.
General Guidelines
1. When mounting to the fixture, avoid contact with metal other than the rear (side opposite of the buttons) and the
end where the wires exit the unit. See “Control Descriptions” for more information.
2. NEVER mount the control module in such a way that the buttons are inaccessible. Doing so will inhibit use of
the equipment, affect RF Range, or both. Do not fully enclose in metal. Some applications (in U.S.A.) require the
PowPak fixture control to be installed inside an additional junction box. For information about how to perform this
installation, please see Lutron Application Note #423 (P/N 048423) at www.lutron.com
3. Keep the top surface (the surface with the buttons) of the module clear of metal and any wiring for 8 in (200 mm)
per the figure on page 2. There is no minimum clearance distance for the bottom of the unit.
4. For more information about PowPak fixture controls, please see Lutron Application Note #556
(P/N 048556) at www.lutron.com
5. The FC-Sensor should be mounted so that the light produced by the attached fixture does not impede daylight
operation.
a. It is suggested that the sensor be mounted below the lit surface of the fixture.
b. Orient the sensor so that the lit surface of the fixture is not directly visible to the daylight lens.
c. Mount the sensor so that the occupancy lens is aimed directly at the the floor of the space.
6. When packaging the completed fixture, be aware of the sensor. Damage can occur to the sensor or its lens
when subjected to contact with the packaging (as in a stack of boxed fixtures).
7. LED drivers and fluorescent lamp ballasts can generate interference that may affect the performance of
wireless controls. Follow the wiring layout guidelines outlined in Appendix 1 to reduce the likelihood of wireless
performance issues.

Appendix 1: Wiring Guidelines for Optimal Performance
NOTE: It is understood that these recommendations may not be able to be followed for all types of fixtures.
Please apply where possible using engineering judgement.
1. Where possible, minimize all wire lengths to achieve the connections in a well organized manner. Avoid leaving
unnecessary slack in the wires. Driver line voltage wiring should exit the fixture wiring channel as close as
possible to the driver to minimize any internal coupling to the fixture control (A). LED/lamp wiring should be
routed away from the fixture control wherever possible (B). In cases where the OEM must provide longer wire
lengths to allow for the removal of fixture trays for fixture mounting, recommend that the OEM utilize shielded
cable if the wiring is to be looped together for storage inside the fixture. Ensure that the shielding is properly
grounded to the fixture metal at both ends of the cable.

2. If the driver is provided with a ground terminal, this terminal should be electrically connected to the grounded
fixture metal as close to the driver as possible.
3. Where possible, mechanically affix wires to the fixture wall so that they are kept as close possible to the
grounded fixture metal.

5. If possible, ensure that the fixture control is mounted away from the LED strips to minimize coupling from the
strips into the fixture control. It may be possible to use the metal from the fixture to shield the fixture control.
This procedure provides a test which can be performed at an OEM to check for gross driver compatibility
issues. It does not guarantee that an issue will not occur in the field due to driver compatibility / noise, however
it can identify moderate and severe issues which would be likely to affect a large number of fixtures. The test
should take about 15 minutes to perform once a fixture is wired up and positioned for the test.
Required Materials:
(1) FCJS-010 RF module
(1) Fixture + 0-10V LED driver
(1) PJ2-2BRL-GWH-L01 Pico RF remote control
1. Ensure a Pico control is associated to the load control. If not, please associate one to it (see FCJS-010
installation instructions on www.lutron.com for details).
2. Turn off all lights in the space or perform this test outside in a flat area like a parking lot. This is to eliminate as
many noise sources as possible. If this cannot be done outside, use a wide open area inside.
3. Move as far away from the test fixture as possible so that you are out of the range of the Pico control (~100 ft
(30 m) or more, depending on conditions).
4. Verify the Pico control does not turn on the fixture. If it does, turn it off (you may need to move closer to do so)
and continue to move farther away.
5. When you are no longer able to turn on the fixture, start slowly moving closer to the fixture while using the Pico
control to try and turn it on.
6. When the fixture turns on, stop. This is point A. Measure the distance to the fixture.
7. Start trying to turn off the fixture. If it does not immediately turn off, start moving closer, while trying to turn it
off.
8. When the fixture turns off, stop. This is point B. Measure the distance to the fixture.
9. Divide distance A over B. If the ratio of A/B is 2 or less, the driver is likely not emitting noise of a level which will
interfere with the Clear Connect communication.
10. If the ratio of A/B is greater than 2, the driver is likely emitting noise at a level which may interfere with Clear
Connect communication. Check the wiring inside the fixture to ensure that recommended practices from
Appendix 1 were followed as much as possible (if necessary, correct) or change the driver. In both cases,
repeat the test to evaluate improvement.
