12.1 Safety notes
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 card. They must be protected from electric shock and contact
with hazardous live circuits.
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, cards should not be operated beyond the full temperature range specified in the
datasheet. Exceeding safe operating conditions can result in shorter lifespans, improper card
performance and user safety issues. When the cards are in use and operation within the
specified full temperature range is not maintained, card 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 card to cool before touching or
removing cards from host computer or chassis.
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 30 V RMS, 42.4 V peak, or 60 V 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
