Looked around and saw similar questions, but not quite what I need. I am replacing a 2X2 fluorescent fixture in my basement with an LED unit (Cree FP22-34L-40K-10V-EB14, install manual at https://www.e-conolight.com/media/productdocuments/document/file/e/s/essentia_install_fp14_fp22_fp24_series.pdf, and wiring diagram is page 3). I didn't realzie it when I got it, but this one has a battery backup. The old one connected to a switch on the wall, so it only has switched voltage. After spending some quality time with a meter and some tape for marking wires, I have found and labeled the hot and neutral coming into the box. I have a handful of other wires going through the box to power the other two lights on the other side of the basement. Looking at the wiring diagram, and thinking this through, I am pretty sure I just need to pigtail the hot from the panel to both the hot and switched hot of the new fixture. The neutrals can all go back the way they were, and the only thing added is the pigtail for the unswitched hot. I am hoping someone can look at the wiring diagram and confirm that I am thinking this through correctly. Thanks!!

  • The manual you linked does not seem to mention a backup battery... – ThreePhaseEel Jun 5 '20 at 3:52
  • Well, fudge. I should have checked it first. I can't find it online for this fixture (one linked on the page is for the standard fixture, I asked Cree to post the correct manual). I added a photo to my OneDrive - 1drv.ms/u/s!AvE5CcGPIhilg-JO2ZqHxLDb1dsDnw?e=19PcVA Thanks for checking this out! – Joe Phillips Jun 5 '20 at 13:21
  • It appears I cannot yet add a photo, so I had to include the link. Basically there are 2 hot leads to the driver, switched hot and unswitched hot. The switched hot comes off the unswitched hot to the driver itself. – Joe Phillips Jun 5 '20 at 13:28
  • The link is fine, as long as it's the right link. The troffer you have linked to does not have a battery backup: it has 0-10V dimming. Please validate your link. Does your actual troffer have a purple and gray wire coming out of it? – Harper - Reinstate Monica Jun 5 '20 at 17:08
  • I added a link above to my OneDrive that shows the wiring diagram. 1drv.ms/u/s!AvE5CcGPIhilg-JO2ZqHxLDb1dsDnw?e=19PcVA The documentation on the web site of the retailer that I originally linked is incorrect for the product. I only made sure I was on the right page. I did not check the accuracy of the PDF itself. I have the purple and gray for a dimmer, but I am not using a dimmer. I have a switched hot, an unswitched hot, and a neutral. – Joe Phillips Jun 5 '20 at 19:51
