Connecting power to the instrument
Connect the power cord to the AC power connector (see page 29 for the AC
power connector location).
Before connecting the mains plug, ensure that the line voltage selection is
appropriate for your location (100 V, 115 V, or 230 V). The mains plug should only
be inserted into a socket outlet that provides protective earth contact.
Push the power switch to turn on the instrument.
The front-panel display illuminates while the power supply performs its power-on
self-test. (If the instrument does not power-on, refer to the steps below). If
self-test is successful, the power supply goes into normal operation.
If the instrument does not turn on
Use the following steps to help solve problems you might encounter when turning
on the instrument. If you need more help, refer to the U8030A Series Service
Guide for instructions on returning the instrument to Keysight Technologies for
service.
1 Verify that there is AC power to the power supply.
First, verify that the power cord is firmly plugged into the power receptacle on
the rear panel of the power supply.
You should also make sure that the power source you plugged the power
supply into is energized. Then, verify that the power supply is turned on.
2 Verify the power-line voltage setting.
The line voltage is set to the proper value for your country when the power
supply is shipped from the factory. Change the voltage setting if it is not
correct. The settings are: 100, 115, or 230 V
AC
.
NOTE
The power supply is shipped from the factory with a power-line cord that has a
plug appropriate for your location. Your power supply is equipped with a
three-wire grounding type power cord; the third conductor being the ground.
The power supply is grounded only when the power-line cord is plugged into an
appropriate receptacle. Do not operate your power supply without an adequate
cabinet ground connection.
