Fuse protection
Ensure adequate fuse protection is provided for the power
supply units
If power supply units other than those recommended in this chapter
are used, this should be reflected in the fuse dimensioning. Note
that the selected fuse can be triggered at a higher current than
16 A with the power supply unit used. Follow the documentation of
the power supply unit manufacturer.
Failure to do so may damage the system in the event of a short cir-
cuit.
