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 frangible coupling and the relevant installation accessories are provided as spare parts.
Disconnect the supply cables of the unit.
Loosen and remove the ring nut. Grab the damaged support with an adjustable wrench in correspondence of the
base of the breakable coupling element. Rotate counterclockwise and remove the support of the fastening flange.
