Keysight 53150A/151A/152A Operating Guide 5
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.
Whenever it is likely that the protection has been impaired, the instrument must
be made inoperative and be secured against any unintended operation.
If this instrument is to be energized via an autotransformer (for voltage reduction),
make sure the common terminal is connected to the earthed pole terminal
(neutral) of the power source.
Instructions for adjustments while covers are removed and for servicing are for use
by trained personnel only. To avoid dangerous electric shock, do not perform such
adjustments or servicing unless qualified to do so.
For continued protection against fire, replace the line fuse(s) with fuses of the
same current rating and type (for example, normal blow, time delay). Do not use
repaired fuses or short-circuited fuseholders.
WARNING
Instructions for adjustments while covers are removed and for servicing are
for use by service-trained personnel only. To avoid dangerous electric shock,
do not perform such adjustments or servicing unless qualified to do so.
WARNING
Any interruption of the protective grounding conductor (inside or outside the
product's circuitry) or disconnecting the protective earth terminal will cause
a potential shock hazard that could result in personal injury (grounding one
conductor of a two conductor outlet is not sufficient protection).
