2.4 Cooling Requirements
This instrument relies on forced air cooling with internal fans and ventilation openings. Care must
be taken to avoid restricting the airflow around the apertures (fan holes) at each side of the
instrument. To ensure adequate ventilation it is required to leave a 15 cm (6 inch) minimum gap
around the sides of the instrument.
CAUTION: Do not block the ventilation holes located on both sides of
the instrument.
CAUTION: Do not allow any foreign matter to enter the instrument
through the ventilation holes, etc.
2.5 Power and Grounding Requirements
The instrument operates with a single-phase, 100 to 240 Vrms (+/- 10%) AC power at 50/60 Hz
(+/- 5%).
No manual voltage selection is required because the instrument automatically adapts to line
voltage.
Depending on the type and number of options and accessories (PC port plug-in, etc.), the
instrument can consume up to 110 W of power.
Note: The instrument automatically adapts to the AC line input within the following ranges:
Voltage Range:
90 - 264 Vrms
Frequency Range:
47 - 63 Hz
The instrument includes a grounded cord set containing a molded three-terminal polarized plug
and a standard IEC320 (Type C13) connector for making line voltage and safety ground
connection. The AC inlet ground terminal is connected directly to the frame of the instrument.
For adequate protection against electrical shock hazards, the power cord plug must be inserted
into a mating AC outlet containing a safety ground contact. Use only the power cord specified
for this instrument and certified for the country of use.
Warning: Electrical Shock Hazard!
Any interruption of the protective conductor inside or outside of the
instrument, or disconnection of the safety ground terminal creates a
hazardous situation.
Intentional interruption is prohibited.
