6 Inverter Operation
1. When properly connected to a 12V outlet, and
when the ON / OFF switch is in the ON position, the
light will glow BLUE, indicating the inverter is
ready.
2. Plug the product(s) you want to operate into the
AC outlet or USB port and switch them on (if
necessary).
Operating Guidelines
• As the battery is used, its voltage begins to fall.
When the XR400/750 senses that the voltage
at its DC input has dropped to 10.5V, the inverter
automatically shuts down and the light glows RED,
indicating a fault. This prevents the battery from
being damaged. Turn off any devices that the
XR400/750 is powering.
