Important test system safety information
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.
You must also realize that in many test systems, a single
fault such as a software error may output hazardous signal
levels, even when the system indicates that there is no
hazard present.
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 VDC 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 VDC rated switch, the maximum
allowed voltage in the system is 300 VDC.
• 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.
