F. High-Speed Cooling Fans. When the temperature inside the inverter
exceeds a preset limit, the Cooling Fans automatically turn on to cool
the inverter. When the temperature reduces, the fans turn off.
G. Positive Power Input Terminal.
H. Negative Power Input Terminal.
I.
Remote Control Receptacle.

K. Main Switch is used for complete shutdown of the inverter.
Determining the DC Power Requirements
Powering multiple appliances from the high-power KR3000 / KR4000
inverter requires a 12 volt bank of batteries (several batteries). To
calculate the approximate power in amps a 12 volt battery bank has to
supply you need. To know the current, or amps required for powering the
continuous AC load, a shortcut method is to divide the continuous AC
load wattage by 10. For example, the continuous AC load is 3000 watts.
The current (amps) is: 3000/10 or 300 amps at 12 VDC.
