Agilent Technologies 6811B Quick Start Manual page 2

Safety Notices
The following general safety precautions
must be observed during all phases of
operation 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 if the customer fails
to comply with these requirements.
WARNING: LETHAL VOLTAGES
Ac sources can supply 425 V peak at
their output. DEATH on contact may
result if the output terminals or circuits
connected to the output are touched
when power is applied. Hazardous
voltages can remain active inside the
unit even after it has been turned off. If
the internal LED's are on, hazardous
voltages are present.
General
This product is a Safety Class 1
instrument (provided with a protective
earth terminal). The protective features of
this product may be impaired if it is used
in a manner not specified in the operation
instructions. Any LEDs in this product are
Class 1 LEDs as per IEC 825-1. This ISM
device complies with Canadian ICES-001.
Cet appareil ISM est conforme à la norme
NMB-001 du Canada.
Environmental Conditions
This instrument is intended for indoor use
in an installation category II, pollution
degree 2 environment. It is designed to
operate at a maximum relative humidity of
95% and at altitudes of up to 2000
meters. Refer to the specification tables
for the ac mains voltage requirements
and ambient operating temperature range.
Do not operate the instrument in the
presence of flammable gases or fumes.
Before Applying Power
Verify that all safety precautions are
taken. Make all connections to the unit
before applying power. Note the
instrument's external markings described
under "Safety Symbols"

Ground the Instrument
To minimize shock hazard, the instrument
chassis and cover must be connected to
an electrical ground. The instrument
must be connected to the ac power mains
through a grounded power cable, with the
ground 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.
Fuses
Only fuses with the required rated
current, voltage, and specified type
(normal blow, time delay, etc.) should be
used. Do not use repaired fuses or short-
circuited fuseholders.
Do Not Remove the Cover
Operating personnel must not remove
instrument covers. Parts replacement and
internal adjustments must be made only
by qualified service personnel.
In Case of Damage
Instruments that appear damaged or
defective should be made inoperative and
secured against unintended operation
until they can be repaired by qualified
service personnel.
CAUTION
A CAUTION notice denotes a hazard. It
calls attention to an operating procedure,
practice, or the like that, if not correctly
performed or adhered to, could result in
damage to the product or loss of
important data. Do not proceed beyond a
CAUTION notice until the indicated
conditions are fully understood and met.
WARNING
A WARNING notice denotes a hazard. It
calls attention to an operating
procedure, practice, or the like that, if
not correctly performed or adhered to,
could result in personal injury or death.
Do not proceed beyond a WARNING
notice until the indicated conditions are
fully understood and met.
