Important safety information for test
systems
This product is sold as a stand-alone instrument that may become part of
a system that could contain hazardous voltages and energy sources. It is
the responsibility of the test system designer, integrator, installer,
maintenance personnel, and service personnel to make sure the system is
safe during use and is operating properly.
It is important that you consider the following factors in your system
design and use:
The international safety standard IEC 61010-1 defines voltages as
hazardous if they exceed 30 V
RMS
and 42.4 V
PEAK
, or 60 V DC for
equipment rated for dry locations. Keithley Instruments products are
only rated for dry locations.
Read and comply with the specifications of all instruments in the
system. The overall allowed signal levels may be constrained by the
lowest rated instrument in the system. For example, if you are using a
500 V power supply with a 300 V DC rated switch, the maximum
allowed voltage in the system is 300 V DC.
Make sure any test fixture connected to the system protects the
operator from contact with hazardous voltages, hot surfaces, and
sharp objects. Use shields, barriers, insulation, and safety interlocks
to accomplish this.
Cover the device under test (DUT) to protect the operator from flying
debris in the event of a system or DUT failure.
Double-insulate all electrical connections that an operator can touch.
Double insulation ensures the operator is still protected even if one
insulation layer fails. Refer to IEC 61010-1 for specific requirements.
Make sure all connections are behind a locked cabinet door or other
barrier. This protects the system operator from accidentally removing
a connection by hand and exposing hazardous voltages. Use
high-reliability fail-safe interlock switches to disconnect power sources
when a test fixture cover is opened.
Where possible, use automatic handlers so operators are not required
to access the DUT or other potentially hazardous areas.
Provide training to all users of the system so they understand all potential
hazards and know how to protect themselves from injury.
To keep users safe, always read and follow all safety warnings provided
with each of the instruments in your system.
