Replacement of the Driver Board
Before carrying out any intervention on the device, cut off all external power sources and
place appropriate work-in-progress warnings on the systems.
Wait for the discharging time (at least 5 minutes) and check using appropriate instruments
that there are no residual energies before accessing the electrical equipment.
Open the fixture and remove the light assembly from the base (see the related paragraph in the chapter
“INSTALLATION”) and bring it to the workshop to complete maintenance.
Unscrew the two captive screws and open the rear cover. Remove the resinated electronic unit, paying attention
not to damage the cables and the internal connections of the fixture.
