Please keep minimum of 2mm clearance (all directions) between inverter high voltage area as marked on
mechanical drawing and any conductors.
Open circuit on all lamps for more than 3 seconds, will shut the inverter down.

Note 3:
In test circuit; 5pF capacitor across the load resistor is add to simulate LCD back-light stray capacitor.
Note 4 :
In test circuit; if any of switches SW3, Sw4 or SW5 opens , then the alarm signal will be activated (+5V).
