Safety Information
The following general safety precau-
tions must be observed during all
phases of operation of this instrument.
Failure to comply with these precau-
tions or with specific warnings or oper-
ating instructions in the product
manuals violates safety standards of
design, manufacture, and intended use
of the instrument. Keysight Technolo-
gies assumes no liability for the cus-
tomer's failure to comply with these
requirements.
General
Do not use this product in any manner not
specified by the manufacturer. The protec-
tive features of this product must not be
impaired if it is used in a manner specified in
the operation instructions.
Before Applying Power
Verify that all safety precautions are taken.
Make all connections to the unit before
applying power. Note the external markings
described under “Safety Symbols”.
Ground the Instrument
Keysight chassis’ are provided with a
grounding-type power plug. The
instrument chassis and cover must be
connected to an electrical ground to
minimize shock hazard. The ground pin
must be firmly connected to an electri-
cal ground (safety ground) terminal 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 per-
sonal injury.
Do Not Operate in an Explosive
Atmosphere
Do not operate the module/chassis in
the presence of flammable gases or
fumes.
Do Not Operate Near Flammable
Liquids
Do not operate the module/chassis in
the presence of flammable liquids or
near containers of such liquids.
Cleaning
Clean the outside of the Keysight mod-
ule/chassis with a soft, lint-free,
slightly dampened cloth. Do not use
detergent or chemical solvents.
Do Not Remove Instrument Cover
Only qualified, service-trained person-
nel who are aware of the hazards
involved should remove instrument
covers. Always disconnect the power
cable and any external circuits before
removing the instrument cover.
Keep away from live circuits
Operating personnel must not remove
equipment covers or shields. Proce-
dures involving the removal of covers
and shields are for use by service-
trained personnel only. Under certain
conditions, dangerous voltages may
exist even with the equipment
switched off. To avoid dangerous elec-
trical shock, DO NOT perform proce-
dures involving cover or shield removal
unless you are qualified to do so.
DO NOT operate damaged
equipment
Whenever it is possible that the safety
protection features built into this prod-
uct have been impaired, either through
physical damage, excessive moisture,
or any other reason, REMOVE POWER
and do not use the product until safe
operation can be verified by service-
trained personnel. If necessary, return
the product to a Keysight Technologies
Sales and Service Office for service and
repair to ensure the safety features are
maintained.
DO NOT block the primary
disconnect
The primary disconnect device is the
appliance connector/power cord when
a chassis used by itself, but when
installed into a rack or system the dis-
connect may be impaired and must be
considered part of the installation.
Do Not Modify the Instrument
Do not install substitute parts or per-
form any unauthorized modification to
the product. Return the product to a
Keysight Sales and Service Office to
ensure that safety features are main-
tained.
In Case of Damage
Instruments that appear damaged or
defective should be made inoperative
and secured against unintended oper-
ation until they can be repaired by
qualified service personnel
Do NOT block vents and fan exhaust:
To ensure adequate cooling and venti-
lation, leave a gap of at least 50mm
(2") around vent holes on both sides of
the chassis.
Do NOT operate with empty slots: To
ensure proper cooling and avoid dam-
aging equipment, fill each empty slot
with an AXIe filler panel module.
Do NOT stack free-standing chassis:
Stacked chassis should be rack-
mounted.
All modules are grounded through the
chassis: During installation, tighten
each module's retaining screws to
secure the module to the chassis and
to make the ground connection.
Operator is responsible to maintain
safe operating conditions. To ensure
safe operating conditions, modules
should not be operated beyond the full
temperature range specified in the
Environmental and physical specifica-
tion. Exceeding safe operating condi-
tions can result in shorter lifespan,
improper module performance and
user safety issues. When the modules
are in use and operation within the
specified full temperature range is not
maintained, module surface tempera-
tures may exceed safe handling condi-
tions which can cause discomfort or
burns if touched. In the event of a
module exceeding the full temperature
range, always allow the module to cool
before touching or removing modules
from the chassis.

Safety Symbols
A CAUTION denotes a hazard. It
calls attention to an operating pro-
cedure or practice, that, if not cor-
rectly 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 condi-
tions are fully understood and met.
A WARNING denotes a hazard. It
calls attention to an operating pro-
cedure or practice, that, if not cor-
rectly performed or adhered to,
could result in personal injury or
death. Do not proceed beyond a
WARNING notice until the indi-
cated conditions are fully under-
stood and met.
