Supply Voltage
n
Setting
The Counter may be connected to any AC
supply with a voltage rating of 90 to 265
V
rms
, 45 to 440 Hz. The counter automati
-
cally adjusts itself to the input line voltage.

Fuse
The secondary supply voltages are electroni
-
cally protected against overload or short cir
-
cuit. The primary line voltage side is protected
by a fuse located on the power supply unit.

replace the fuse under any operating condi
-
tions, nor is it accessible from the outside.
