Safety Summary
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. Hewlett-Packard
Company assumes no liability for the customer's failure to comply
with these requirements.
General This is a Safety Class 1 instrument (provided with
terminal for protective earthing) and has been manufactured and
tested according to international safety standards.
Operation – Before applying power Comply with the
installation section. Additionally, the following shall be observed:
• Do not remove instrument covers when operating.
• Before the instrument is switched on, all protective earth
terminals, extension cords, auto-transformers and devices
connected to it should be connected to a protective earth via a
ground socket. Any interruption of the protective earth
grounding will cause a potential shock hazard that could result
in serious personal injury.
• Whenever it is likely that the protection has been impaired, the
instrument must be made inoperative and be secured against any
unintended operation.
• Make sure that only fuses with the required rated current and of
the specified type (normal blow, time delay, etc.) are used for
replacement. The use of repaired fuses and the short-circuiting
of fuseholders must be avoided.
• Adjustments described in the manual are performed with power
supplied to the instrument while protective covers are removed.
Be aware that energy at many points may, if contacted, result in
personal injury.
• Any adjustments, maintenance, and repair of the opened
instrument under voltage should be avoided as much as possible,
and when unavoidable, should be carried out only by a skilled
person who is aware of the hazard involved. Do not attempt
internal service or adjustment unless another person, capable of
rendering first aid and resuscitation is present. Do not replace
components with power cable connected.
