Safety Considerations
Read the information below before using this instrument.
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 for design, manufacture, and intended use of the instrument. Keysight
Technologies assumes no liability for the customer’s failure to comply with these
requirements.
CAUTION
BEFORE APPLYING POWER.
Verify that the product is set to match the available line voltage and that the
correct fuse is installed.
CAUTION
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 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).
CAUTION
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
