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 datasheet. 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 card exceeding the full
temperature range, always allow the module to cool before touching.
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
60V DC 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 modules directly to unlimited power circuits. They are intended to be used with
impedance-limited sources. NEVER connect modules directly to AC mains. When connecting
sources to modules, install protective devices to limit fault current and voltage to the module.
Before operating a card, 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 ADC modules, 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 module 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 modules and accessories, as defined in the
specifications and operating information, and as shown on the module or test fixture panels, or
ADC module.
