d) disconnect the mains,
e) adjust R to give I = I . b (or I . a if no I . b is specified),
L max max max
f) measure the output voltage(s) for 2 min and check if they are within the specification.
NOTE R max is specified by the PSE manufacturer for the purpose of the test. It is intended to simulate the
