2 Getting Started
Before connecting and powering up the instrument, please review and go through the
instructions in this chapter.
2.1 Input Power Requirements
The supply has a universal AC input that accepts line voltage input within:
Voltage: 110 V to 240 V (±10%)
Frequency: 50 Hz to 60 Hz (±5%)
Power supply power range: ≤ 30VA
The instrument has 50 and 60 Hz user selectable line filter in . Select 50 Hz or 60 Hz to match
the line frequency. If the input power line has excessive noise, additional external noise
filtering may be required.
Before connecting to an AC outlet or external power source, make sure that the power switch is
in the OFF position and verify that the AC power cord, including the extension line, is
compatible with the rated voltage/current and that there is sufficient circuit capacity for the
power supply. Once verified, connect the cable firmly.
The included AC power cord is safety certified for this instrument operating in
rated range. To change a cable or add an extension cable, be sure that it can meet
the required power ratings for this instrument. Any misuse with wrong or unsafe
cables will void the warranty.
2.2 Fuse Requirements
An AC input fuse is necessary when powering the instrument. The fuse is located at the back of
the instrument. In the event the fuse needs to be replaced, make sure the AC input power cord
is disconnected from the instrument before replacing. The below table shows the fuse required
for all specified AC input voltages.
Before replacing fuse, disconnect AC input power cord first to prevent electric shock.
Only use a fuse of the same rating as required. Using a different rated fuse will damage
the instrument.
