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" in the User's Guide for addi-
tional 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 operation
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
