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 protect
themselves from the risk of electric shock. If
the circuit is capable of operating at or
above 1000V,
no conductive part of the circuit may be
exposed.
Do not connect switching cards directly to
unlimited power circuits. They are
intended to be used with impedance-
limited sources. NEVER connect switching
cards directly to AC mains. When
connecting sources to switching cards,
install protective devices to limit fault
current and voltage to the card.
Before operating an instrument, ensure
that the line cord is connected to a
properly grounded power receptacle.
Inspect the connecting cables, test leads,
and jumpers for possible wear, cracks, or
breaks before each use.
When installing equipment where access
to the main power cord is restricted, such
as rack mounting, a separate main input
power disconnect device must be
provided in close proximity to the
equipment and within easy reach of the
operator.
For maximum safety, do not touch the
product, test cables, or any other
instruments while power is applied to the
circuit under test. ALWAYS remove power
from the entire test system and discharge
any capacitors before: connecting or
disconnecting cables or jumpers,
installing or removing switching cards, or
making internal changes, such as
installing or removing jumpers.
Do not touch any object that could
provide a current path to the common
side of the circuit under test or power line
(earth) ground. Always make
measurements with dry hands while
standing on a dry, insulated surface
capable of withstanding the voltage being
measured.
The instrument and accessories must be
used in accordance with its specifications
and operating instructions, or the safety of
the equipment may be impaired.
Do not exceed the maximum signal levels
of the instruments and accessories, as
defined in the specifications and operating
information,and as shown on the
instrument or test fixture panels, or
switching card.
