Safety Information
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.
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.
The following safety precautions
should be observed before using
this product and any associated
instrumentation. This product is
intended for use by qualified
personnel who recognize shock
hazards and are familiar with the
safety precautions required to avoid
possible injury. Read and follow all
installation, operation, and
maintenance information carefully
before using the product.
If this product is not used as specified, the
protection provided by the equipment
could be impaired. This product must be
used in a normal condition (in which all
means for protection are intact) only.
The types of product users are:
–Responsible body is the
individual or group responsible
for the use and maintenance of
equipment, for ensuring that the
equipment is operated within its
specifications and operating
limits, and for ensuring
operators are adequately
trained.
–Operators use the product for
its intended function. They must
be trained in electrical safety
procedures and proper use of
the instrument. They must be
protected from electric shock
and contact with hazardous live
circuits.
–Maintenance personnel
perform routine procedures on
the product to keep it operating
properly (for example, setting
the line voltage or replacing
consumable materials).
Maintenance procedures are
described in the user
documentation. The procedures
explicitly state if the operator
may perform them. Otherwise,
they should be performed only
by service personnel.
–Service personnel are trained
to work on live circuits, perform
safe installations, and repair
products. Only properly trained
service personnel may perform
installation and service
procedures.
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 specification. Exceeding safe
operating conditions can result in shorter
lifespans, 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
temperatures may exceed safe
handling conditions 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 chassis.
Keysight products are designed for
use with electrical signals that are
rated Measurement Category I and
Measurement Category II, as
described in the International
Electro-technical Commission (IEC)
Standard IEC 60664. Most
measurement, control, and data I/O
signals are Measurement Category
I and must not be directly
connected to mains voltage or to
voltage sources with high transient
over-voltages. Measurement
Category II connections require
protection for high transient over-
voltages often associated with local
AC mains connections. Assume all
measurement, control, and data I/O
connections are for connection to
Category I sources unless
otherwise marked or described in
the user documentation.
Exercise extreme caution when a
shock hazard is present. Lethal
voltage may be present on cable
connector jacks or test fixtures. The
American National Standards
Institute (ANSI) states that a shock
hazard exists when voltage levels
greater than 30V RMS, 42.4V peak,
or 60VDC are present. A good
safety practice is to expect that
hazardous voltage is present in any
unknown circuit before measuring.
Operators of this product must be
protected from electric shock at all
times. The responsible body must
ensure that operators are
prevented access and/or insulated
from every connection point. In
some cases, connections must be
exposed to potential human
contact. Product operators in these
circumstances must be trained to
