is different for different circuits of the Device
Supplementary
insulation (SI)
Independent insulation used in addition to the basic insulation in order to
guarantee protection against electric shock in the event of a failure of the
main insulation The electrical strength of the supplementary insulation is
checked by type tests: by applying an alternating test AC voltage of
various levels (RMS value)
