2.3.3. Installation
2.3.3.1. Supply Voltage
Setting
The Counter may be connected to any AC supply with a voltage rating of 90 to 265 Vrms, 45 to 440 Hz. The counter
automatically adjusts itself to the input line voltage.
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. Do not replace the fuse. Send the counter to the local Service
Center.
Removing the cover for repair, maintenance and adjustment must be done by qualified and trained personnel only, who
are fully aware of the hazards involved.
The warranty commitments are rendered void if unauthorized access to the
interior of the instrument has taken place during the given warranty period.
