Normal condition
Single fault condition
Normal condition
Single fault condition
Single fault condition
Single fault condition
Single fault condition
Interruption of a protective
earth conductor
Interruption of one
supply conductor
Interruption of one
supply conductor
A voltage equivalent to 110% of
the maximum rated voltage is
applied between the signal input or
output part which is not protectively
earthed and the earth
(medical electrical equipment only)
Currents between the enclosure and
the earth, and between parts of the
enclosure are measured.
Normal condition
Single fault condition
A current between the protective earth
terminal and the earth is measured.
A current is measured between
the applied and the earth.
A current is measured between
the applied part and the earth.
A current is measured between
parts of the applied part.
A current is measured between
the F-type applied part and the
faulty equipment.
A voltage equivalent to 110%
of the maximum rated voltage
is applied between the F-type
applied part and the earth.
Interruption of one
supply conductor
Interruption of a protective
earth conductor
Normal condition
Interruption of one
supply conductor
Interruption of a protective
earth conductor
A voltage equivalent to 110% of
the maximum rated voltage is
applied between the signal input or
output part which is not protectively
earthed and the earth
(medical electrical equipment only)
NOTE
1.4 Leakage Measurement Types
・ Measurements including the combined single fault conditions is not possible.
・ The optional 9196 APPLY UNIT is required to apply a voltage equivalent to
110% of the maximum rated voltage.
