SMU terminals and connectors
The locations and configuration of the SMU terminals are shown in the following figure. Basic
information about these terminals is summarized below.
Asserting the interlock allows the SMU and preamplifier terminals to become hazardous,
exposing the user to possible electrical shock that could result in personal injury or death.
SMU and preamplifier terminals should be considered hazardous even if the outputs are
programmed to be low voltage. Precautions must be taken to prevent a shock hazard by
surrounding the test device and any unprotected leads (wiring) with double insulation that is
rated for 250 V, Category O.
The maximum allowed voltage between COMMON and chassis ground is ±32 V dc.
