4.5 Replacement of the 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 complete support, diversified depending on the type and position (fixed installation or mobile installation, front
or rear support) or the frangible coupling are provided as spare parts. If necessary, assemble the new spare part
support (see related paragraph in the chapter “INSTALLATION”).
Disconnect the supply cables of the unit.
Unscrew the upper locking nuts and extract the spherical washers. Remove the supports.
