Pre-charge of internal line capacitors is too fast or capacitors
voltage is fixed to zero during precharge.
Pre-charge phase fails to charge capacitors till the voltage level of
key input.
Before closing the line contactor, internal capacitors are loaded
for short time and voltage doesn't go down.
Main Contactor Did Not
Close
The difference between key switch and capacitors voltage is too
high after the contactor has been powered.
Interlock input is not active and line contactor is open.
