Safety Summary; Safety Symbols - Agilent Technologies E3630A Manual De Funcionamiento Y Servicio

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. Agilent Technologies assumes no liability for the customer's failure to comply
with these requirements.
BEFORE APPLYING POWER.
Verify that the product is set to match the available line volt-
age and that the correct fuse is installed.
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 reduc-
tion, 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.
Do not operate the instrument in the presence of flammable
gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers.
Component replacement and internal adjustments must be
made by qualified service personnel. Do not replace compo-
nents with power cable connected. Under certain conditions,
dangerous voltages may exist even with the power cable
removed. To avoid injuries, always disconnect power, dis-
charge circuits and remove external voltage sources before
touching components.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another
person, capable of rendering first aid and resuscitation, is
present.
Instruments that appear damaged or defective should be made inoperative and secured against unintended
operation until they can be repaired by qualified service personnel.
