1) Vsus (173V) Voltage CHECK: When keeping above 10 volt, Using not less than 1 K ohm 5
Watt resistance to discharge remaining voltage.(Under 5 volt )
2) Vadd (68V) Voltage CHECK: When keeping above 10 volt, Using not less than 1 K ohm 5
Watt resistance to discharge remaining voltage.(Under 5 volt )
7. Check the Connectors Connection.
8. If no fault detected from above tests, do the following.
(1) Use DIODE TESTER reffering to the following Table.1~4.
(2) If abnormal components CHECK, then replace Y-SUS PCB.
(3) If NORMAL, Check the Connectors' Connection again.
