Driver Replacement Steps
For Backlit Troffer 22 and 24: unfasten the screw(s) holding the driver cover and remove it.
For Backlit Troffer 14: unfasten the screws near the LED bar and remove the cover.
First, disconnect the driver from the luminaire by
cutting the wires at the distance of 2 cm (0.75 in.)
from the old driver. Then, unscrew the screws
and star washers which attach the driver to the
luminaire and remove the old driver.
NOTE: Keep the screws and star washers for later use.
The length of wires from the new driver should
be no less than 6 cm (2.36 in.). Reattach the new
driver in the same location as the old driver using
star washers and screws. Strip off 10 mm (0.4 in.)
from all wires and reconnect the new driver to the
luminaire with UL-certied connectors. Wires with
the same color should be connected together.
