Safety Summary
General Safety Precautions
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 Inc. assumes no
liability for the customer's failure to comply
with these requirements.
Before operation, review the instrument and
manual for safety markings and instructions.
You must follow these to ensure safe
operation and to maintain the instrument in
safe condition.
Initial Inspection
Inspect the shipping container for damage. If
there is damage to the container or
cushioning, keep them until you have
checked the contents of the shipment for
completeness and verified the instrument
both mechanically and electrically. The
Performance Tests give procedures for
checking the operation of the instrument. If
the contents are incomplete, mechanical
damage or defect is apparent, or if an
instrument does not pass the operator’s
checks, notify the nearest Agilent
Technologies Sales/Service Office.
WARNING To avoid hazardous electrical
shock, do not perform electrical tests when
there are signs of shipping damage to any
portion of the outer enclosure (covers,
panels, etc.).
General
This product is a Safety Class 1 product
(provided with a protective earthing ground
incorporated in the power cord). The mains
plug shall only be inserted in a socket outlet
provided with a protective earth contact.
Any interruption of the protective conductor,
inside or outside of the instrument, will
make the instrument dangerous. Intentional
interruption is prohibited.
Environment Conditions
This instrument is intended for indoor use in
an installation category II, pollution degree 2
environment per IEC 61010 Second Edition
and 664 respectively. It is designed to
operate within a temperature range of 10 to
40 °C at a maximum relative humidity of 80%
for temperatures up to 31 °C, decreasing
linearly to 50% relative humidity at 40 °C at
an altitude of 2000 meters.
This module can be stored or shipped at
temperatures between -40°C and +70°C.
Protect the module from temperature
extremes that may cause condensation
within it.
Before Applying Power
Verify that all safety precautions are taken.
The power cable inlet of the instrument
serves as a device to disconnect from the
mains in case of hazard. The instrument
must be positioned so that the operator can
easily access the power cable inlet. When
the instrument is rack mounted the rack
must be provided with an easily accessible
mains switch.
Ground the Instrument
Install the instrument so that the ON / OFF
switch is readily identifiable and is easily
reached by the operator. The ON / OFF
switch is the instrument disconnecting
device. It disconnects the mains circuits
from the mains supply before other parts of
the instrument. Or the detachable power
cord can be removed from the electrical
supply. Alternately, an externally installed
switch or circuit breaker which is readily
identifiable and is easily reached by the
operator may be used as a disconnecting
device.
Do Not Operate in an Explosive
Atmosphere
Do not operate the instrument in the
presence of flammable gases or fumes.
Do Not Remove the Instrument
Cover
Operating personnel must not remove
instrument covers. Component replacement
and internal adjustments must be made only
by qualified personnel.
Instruments that appear damaged or
defective should be made inoperative and
secured against unintended operation until
they can be repaired by qualified service
personnel.
