Setting
The Counter may be connected to any AC supply with a volt-
age rating of 90 to 265 V
rms
, 45 to 440 Hz. The counter auto-
matically adjusts itself to the input line voltage.
n
Fuse
The secondary supply voltages are electronically protected
against overload or short circuit. The primary line voltage side
is protected by a fuse located on the power supply unit. The
fuse rating covers the full voltage range. Consequently there
is no need for the user to replace the fuse under any operating
conditions, nor is it accessible from the outside.
CAUTION: If this fuse is blown, it is likely
that the power supply is badly damaged.
Replace the complete power supply unit.
Do not replace the fuse.
