Replacement of the LHA support
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.
The support is a complete spare part, diversified depending on the type and position (fixed installation or mobile
installation, front or rear support).
Disconnect the supply cables of the LHA unit. Remove the upper cover (1a) of the fixture and access the LED
module (1b) (see related paragraph in the chapter "ADJUSTMENTS AND MAINTENANCE").
Unscrew the three upper locking nuts (2a) and extract the spherical washers. Remove the LHA supports.
