Replacement of the front glass
Before carrying out any intervention on the fixture, 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.
If the glass shows signs of damage or breakdowns, proceed with replacement. Unscrew the four screws and
remove the frame unit (complete with gasket).
Remove the front glass.
Replace the gaskets (lower -if any- and upper). Position the new glass.
Position the frame unit (complete with gasket) on the body, paying attention not to crush the connection cables.
Screw the four screws alternately until the expected tightening torque is reached.
