ballast housing and remove components and their
wiring. (Fully remove the core of the luminaire and
clean it.)

(VB) through the round opening in the housing par-
tition into the lamp compartment. Swing the LED
operating device carrier into the operating device
compartment as shown. Fix in the existing threaded
holes with the enclosed M4x8 screws.

minal (KB) in the driver housing rear panel. Close
the cover again.

necting cable is pulled forward into the lamp com-
partment and is not pinched.
• (D) Connect the 4-pole plug of the connecting cable
to the coupling on the LED module (LM). Position
the LED module (LM) on the support bracket with its
keyholes over the screws (SM). Make sure that it is
correctly aligned.

the front of the luminaire!) Tighten screws (SM) and
close the luminaire cover again.

function.
