There is a mains fuse in the mains socket, accessible from the outside of the
unit. This may be changed by the user. The current consumption of the unit is
very low (150 mA at 110 V) so it only blows if there is a fault - usually if the unit
is set to its low voltage setting (100 - 120V) but has been plugged into a high
voltage mains (220 - 240V). Usually no other damage is caused, but if the fuse
blows repeatedly on replacement, some other damage will have been done and
the unit must be returned to dCS for repair.

Fuse Type :
20 x 5mm 2 amp HRC fuse
If the fuse should fail, it is essential that it be replaced with one of the same type.
Failure to do so could result in damage to the unit and may invalidate the
guarantee. To gain access to the fuse, remove the IEC mains connector, use a
small flat bladed screwdriver to pry up the tab on the fuse carrier and pull it out.
Push the fuse out of the clip in the carrier and replace it with a new one. Push
the carrier back into the unit so that it clicks home.
