BURNING TEST
Leave the unit connected to its nominal mains voltage during 24 hours.
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
Ω
.
Electrical insulation test:
Connect the electrical insulation tester probes between the mains outlet ground contact and both shorted
mains input poles.
Adjust the tester’s current limit down to 10mA.
Apply 1500Vac 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!
QUALITY CONTROL
All mechanical parts should be visually revised, in order to detect scratches on the unit's painting; all
screws should be on their place, correctly tight and unmarked. Check out the unit's general presentation.
