Safety Considerations - Keysight Technologies 11713B Operating And Service Manual

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
WARNING
– Verify that the correct fuse is installed.
– Ensure the mains supply voltage fluctuation do not exceed ±10% of the nominal supply
voltage.
GROUND THE INSTRUMENT
WARNING
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 disconnection 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 autotransformer
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
WARNING
Do not operate the device around flammable gases or fumes, vapor, or wet environments.
DO NOT OPERATE DAMAGED OR DEFECTIVE INSTRUMENTS
WARNING
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
WARNING
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.
