SAFETY VERIFICATION TESTS
Preliminary:
Unplug the unit to be tested from the mains outlet.
Short all ground terminals from signal inputs, outputs and other external connectors, except the mains
plug’s ground.
Turn ON the unit’s main power switch.
Ground continuity test:
Connect the tester probes between the mains ground contact and the unit’s backside main ground test
point. When applying a 10A current, verify that the
ground impedance is lower than 0’1

.
Electrical insulation test:
Test 1
– Between L/N and earthed enclosure:
Connect the electrical insulation tester probes between both shorted mains input poles (L/N) and earthed
metal enclosure.
Adjust the tester’s current limit down to 10mA.
Apply 1600VAC during 5 seconds.
The unit’s insulation should be able to resist this voltage, without generating spurious sparks or a
sparkover effect, and the tester may not detect any malfunction.
Test 2
– Between L/N and secondary accessible terminals:
Connect the electrical insulation tester probes between both shorted mains input poles (L/N) and the
output/input connectors of audio signal.
Adjust the tester’s current limit down to 10mA.
Apply 2550VAC during 5 seconds.
The unit’s insulation should be able to resist this voltage, without generating spurious sparks or a
sparkover effect, and the tester may not detect any malfunction.
CAUTION: Do not disconnect nor touch the test probes until the test has finished completely!
