The maximum floating (common mode) voltage for a SMU is ±250V.
Exceeding this level may cause damage to the instrument and
create a shock hazard.
Using an external source to float a SMU could create a shock
hazard in the test circuit. A shock hazard exists whenever >42V
peak is present in the test circuit. Appropriately rated cables or
insulators must be provided for all connections to prevent access
to live parts
When >42V is present, the test circuit must be insulated for the
voltage used or surrounded by a metal safety shield that is
connected to a known safety earth ground and chassis ground (see
"Safety shield" earlier in this section).
