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 1000 V, 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.
For safety, instruments and accessories must be used in accordance with the operating
instructions. If the instruments or accessories are used in a manner not specified in the
operating instructions, the protection provided by the equipment may be impaired.
Do not exceed the maximum signal levels of the instruments and accessories. Maximum
signal levels are defined in the specifications and operating information and shown on the
instrument panels, test fixture panels, and switching cards.
When fuses are used in a product, replace with the same type and rating for continued
protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT
as protective earth (safety ground) connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under
test. Safe operation requires the use of a lid interlock.
If a
screw is present, connect it to protective earth (safety ground) using the wire
recommended in the user documentation.
The
symbol on an instrument means caution, risk of hazard. The user must refer to
the operating instructions located in the user documentation in all cases where the symbol is
marked on the instrument.
The
symbol on an instrument means warning, risk of electric shock. Use standard
safety precautions to avoid personal contact with these voltages.
