2 Getting Started
Before connecting and powering up the instrument, please review and go through the
instructions in this chapter.
2.1 Input Power and Fuse Requirements
2.1.1 Input Power
The supply has a universal AC input that accepts line voltage input within:
AC Input: 210 V – 240 V
Frequency: 47 Hz – 63 Hz
Before connecting to an AC outlet or external power source, be 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.
When the AC input voltage is lower than the full-load voltage, which is 200VAC, the supplies will
activate an inner over temperature protector and cut off the output in response to the condition. To
ensure that the entire test process can be completed smoothly, confirm that the input AC voltage
is within the specified range. 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.
SHOCK HAZARD:
The power cord provides a chassis ground through a third conductor. Verify that
your power outlet is of the three-conductor type with the correct pin connected to
earth ground.
Follow the instructions below to connect the AC power cable to the AC input of the power supply in
the rear panel.
