REPLACING FUSES
WARNING: This operation must be performed only by qualified personnel.
1) Disconnect the plug from the mains socket.
2) Remove the rear panel and remove the fusebox capsule by rotating it anticlockwise through half a turn and replace the burnt fuse with a new fuse
having identical features (See Technical Data Table page 42).
3) ATTENTION: In three-phase models, the ceramic fuse PF5 is not fixed on the power board but is positioned on the side of the remote control
switches inside the electric panel.
