9. Internal fuses and configuration

9.1 Internal extra-low voltage fuse
If there seems to be no supply voltage in a device, the rear side mains fuse and the internal extra-
low voltage fuse have to be checked first – see photo below. Of course only fuses with identical
value may be used.
The internal extra-low voltage fuses are fitted with fuse links 5x20 mm 15 Amperes.
