Page 6: Voltage Supply
Voltage Supply The power board voltage supply is wired with the power contactor. On starting the generator, voltage is supplied to the power board. The transformer is connected directly at the entrance of the power supply. The transformer supplies two diff erent voltages: 230VAC for the power contactor and the fan as well as 23VAC for the low voltage supply. -
