To prepare the Power Supply for Use
The following steps help you verify that the power supply is ready for use.
1 Check the list of supplied items.
Verify that you have received the following items with your power supply. If
anything is missing, contact your nearest Keysight Technologies Sales Office.
– One power cord for your location.
– This User’s Guide.
– One Service Guide.
– Certificate of Calibration.
2 Verify that the correct power-line voltage setting is selected and that the
correct power-line fuse is installed.
The line voltage is set to 100, 115 or 230 Vac from the factory according to the
input power option selected when you ordered the power supply. Change the
voltage setting if it is not correct for your location (see the next page for
detailed information). For 100 or 115 Vac operation, the correct fuse is 6.3 AT
(Keysight part number 2110-1030) and for 230 Vac operation, the correct fuse
is 3.15 AT (Keysight part number 2110-1031).
3 Connect the power cord and turn on the power supply.
A power-on self-test occurs automatically when you turn on the power supply.
The front-panel display will light up while the power supply performs its
power-on self- test. After performing the self-test, the power supply will go
into the power-on / reset state; the output is disabled (the OFF annunciator
turns on); the 8V/20A
[1]
or 25V/7A
[2]
range is selected (the 8V
[1]
or 25V
[2]
annunciator turns on); the knob is selected for voltage control.
Notice that the OVP and OCP annunciators also turn on.
