The following general safety precautions must be observed during all phases of operation
of this instrument. Failure to comply with these precautions or with specific warnings or
operating instructions in the product manuals 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. Product manuals
are provided on the Web. Go to

This product is a Protection Class 1 instrument (provided with a protective earth terminal)
and has been manufactured and tested according to international safety standards. The
protective features of this product may be impaired if it is used in a manner not specified
in the operation instructions.
All Light Emitting Diodes (LEDs) used in this product are Class 1 LEDs as per
IEC 60825-1:2014.
This instrument is intended for indoor use in an Overvoltage Category II, pollution degree
2 environment. It is designed to operate at a maximum relative humidity of 85% RH,
non-condensing and at altitudes of up to 2000 meters. Refer to the specifications tables
for the AC mains voltage requirements and ambient operating temperature range.
The instrument should be protected from temperature extremes and changes in
temperature that may cause condensation within it.
The operating temperature is from 5 °C to +40 °C.
The storage temperature is from -40 °C to +70 °C.
Verify that all safety precautions are taken. The power cable inlet of the instrument serves
as a device to disconnect from the mains in case of hazard. The instrument must be
positioned so that the operator can easily access the power cable inlet. When the
instrument is rack mounted the rack must be provided with an easily accessible mains
switch.
To minimize shock hazard, the instrument chassis and cover must be connected to an
electrical protective earth ground. The instrument must be connected to the AC power
mains through a grounded power cable, with the ground wire firmly connected to an
electrical ground (safety ground) at the power outlet. Any interruption of the protective
(grounding) conductor or disconnection of the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
Do not operate the instrument in the presence of flammable gases or fumes.
Operating personnel must not remove instrument covers. Component replacement and
internal adjustments must be made only by qualified personnel.
Instruments that appear damaged or defective should be made inoperative and secured
against unintended operation until they can be repaired by qualified service personnel.
