Safety and Regulatory Information
Safety Considerations
The following general safety precautions must be observed during all phases of operation, service, and repair of this
instrument. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates
safety standards of design, manufacture, and intended use of the instrument. Keysight Technologies assumes no
liability for the customer's failure to comply with these requirements.
BEFORE APPLYING POWER
– Verify that the product is set to match the available line voltage and that the correct fuse is installed. Use the label
on the rear of the instrument to configure the power. See Options and Fuse Information for additional details.
– Ensure the mains supply voltage fluctuation do not exceed ±10% of the nominal supply voltage.
GROUND THE INSTRUMENT
This product is a Safety Class I instrument (provided with a protective earth terminal). To minimize shock hazard, the
instrument chassis and cabinet must be connected to an electrical ground. The instrument must be connected to the
AC power supply mains through a three-conductor power cable, with the third wire firmly connected to an electrical
ground (safety ground) at the power outlet. Any interruption of the protective(grounding) conductor or dis-
connection of the protective earth terminal will cause a potential shock hazard that could result in personal injury. If
the instrument is to be energized via an external autotransformer for voltage reduction, be certain that the auto-
transformer common terminal is connected to the neutral (earthed pole) of the AC power lines (supply mains).
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE OR WET ENVIRONMENTS
Do not operate the device around flammable gases or fumes, vapor, or wet environments.
DO NOT OPERATE DAMAGED OR DEFECTIVE INSTRUMENTS
Instruments that appear damaged or defective should be made inoperative and secured against unintended oper-
ation until they can be repaired by qualified service personnel.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized
modification to the instrument. Return the instrument to a Keysight Technologies Sales and Service Office for service
and repair to ensure that safety features are maintained. To contact Keysight for sales and technical support, refer to
the support links on the following Keysight website: www.keysight.com/find/assist (worldwide contact inform-
ation for repair and service).
USE THE POWER CORD PROVIDED
Use the device with the power cord provided with the shipment.
USE THE DEVICE AS SPECIFIED
If the device is used in a manner not specified by manufacturer, the device protection may be impaired.
DO NOT BLOCK VENTILATION HOLES
Do not block any of the ventilation holes of the device.
OBSERVE ALL DEVICE MARKINGS BEFORE CONNECTING TO DEVICE
Observe all markings on the device before connecting any wiring to the device.
Keysight EDU36311A User's Guide 7

TURN DEVICE OFF BEFORE CONNECTING TO OUTPUT TERMINALS
Turn off the device power before connecting to the output terminals.
ENSURE COVER IS SECURED IN PLACE
Do not operate the device with the cover removed or loosened.
TURN DEVICE OFF ANDREMOVEALL CONNECTIONS BEFORE INSTALLING THEGPIB INTERFACE
Turn off the power and remove all connections, including the power cord, from the instrument prior installation of
the GPIB interface.
CLEAN WITH SLIGHTLY DAMPENED CLOTH
Clean the outside of the instrument with a soft, lint-free, slightly dampened cloth. Do not use detergent, volatile
liquids, or chemical solvents.
Connect USB cable with ferrite core to the rear panel USB port of the instrument.

Options and Fuse Information
Ensure you order the proper instrument option for the mains power that will be used for the instrument.
Options 0EM, 0E3, and 0E9 determine which power-line voltage is selected at the factory.
Option Description
0EM 115 VAC ± 10%, 50/60 Hz input voltage
0E3 230 VAC ± 10%, 50/60 Hz input voltage
0E9 100 VAC ± 10%, 50/60 Hz input voltage
Ensure the correct AC input voltage and fuse settings
Use the proper switch settings
To change the input AC voltage selector on the power supply, use the two AC selector switches on the upperside of
the power supply as shown.
For example, to select 230 V, slide both switches to the left, as illustrated in the diagram below the switches.
To select 115 V, slide the upper switch to the right and the lower switch to the left.
To select 100 V, slide both switches to the right.
