Safety and Support Information
Ground the System
To minimize shock hazard, the
system chassis must have a
hard-wired connection to an
electrical protective earth
ground. The system must also be
connected to the ac power mains
through a power cable that
includes a protective earth
conductor. The power cable
ground wire must be connected
to an electrical ground (safety
ground) at the power outlet. Any
interruption of the protective
grounding will cause a potential
shock hazard that could result in
personal injury.
Fuses
Use only fuses with the required
rated current, voltage, and
specified type (normal blow,
time delay). Do not use repaired
fuses or short-circuited fuse
holders. To do so could cause a
shock or fire hazard.
Operator Safety Information
MODULE CONNECTORS AND
TEST SIGNAL CABLES
CONNECTED TO THEM
CANNOT BE OPERATOR
ACCESSIBLE: Cables and
connectors are considered
inaccessible if a tool (e.g.,
screwdriver, wrench, socket,
etc.) or a key (equipment in a
locked cabinet) is required to
gain access to them.
Additionally, the operator
cannot have access to a
conductive surface connected to
any cable conductor (High, Low
or Guard).
ASSURE THE EQUIPMENT
UNDER TEST HAS
ADEQUATE INSULATION
BETWEEN THE CABLE
CONNECTIONS AND ANY
OPERATOR-ACCESSIBLE
PARTS (DOORS, COVERS,
PANELS, SHIELDS, CASES,
CABINETS, ETC.): Verify there
are multiple and sufficient
protective means (rated for the
voltages you are applying) to
assure the operator will NOT
come into contact with any
energized conductor even if one
of the protective means fails to
work as intended. For example,
the inner side of a case, cabinet,
door, cover or panel can be
covered with an insulating
material as well as routing the
test cables to the module's front
panel connectors through
non-conductive, flexible conduit
such as that used in electrical
power distribution.
Safety Symbols and
Regulatory Markings
Symbols and markings on the
system, in manuals and on
instruments alert you to
potential risks, provide
information about conditions,
and comply with international
regulations.
Table 1
defines the
symbols and markings you may
encounter.
