1-6 . Insulation Resistance
1) Test Requirements – Input Voltage : 500Vdc
– Temperature : 25℃± 5℃
2) A method of measurement : Test between Utility (live and neutral short) and output line (+ and - short).
(insulation resistance test)
3) Criterion for Judging : Insulation resistance ≧ 100MΩ 2. INVERTER TEST: 2-1. OPEN LAMP PROTECT
TEST :
Test Condition : ON/OFF PIN=3.3Vdc or 5.0Vdc , BL-Adj PIN=3.3Vdc or 5.0Vdc . Result : CN901~CN904
OPEN , INVERTER TURN ON CONTINUE 1~2 SECONDS SHUT DOWN .
