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 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.
