System Failure
In case of errors or failure due to a loss of power during testing, additional
precaution is required. The HVA LED red
light cannot indicate when residual
voltage is less than 100 V. To guarantee that the residual voltage has dissipated
before removing the test lead, the DUT must be de-energized using a discharge
stick.
Steps
D1*-D7*
describe the
disconnection
procedure in case of
system failure.
Step
Procedure
(system failure disconnection)
D1*
Switch HVA OFF
Press emergency OFF
•
Turn the HVA main switch
off
•
Lock HVA in disabled state to prevent unauthorized use:
Turn key switch
to OFF position and remove key
D2*
•
Verify correct functioning of discharge stick
D3*
Discharge and earth the DUT complying with local safety regulations
•
Discharge DUT using a discharge stick
D4*
Before disconnecting test lead,
wait
until residual voltage has dissipated
•
Required wait time depends on the resistance of the discharge stick
•
Rule of thumb: For standard discharge sticks, wait a minimum of 10 min.
D5*
Disconnect the test lead
•
Disconnect the test lead from the DUT
•
Unscrew the test lead from the HV output connector
D6*
Disconnect power supply cable from power supply plug
D7*
Disconnect earth
•
Disconnect the earthing cable from the HVA earthing connector
