Although ResMed S8 series devices operate from 12V DC the DC input ports run opposite polarity from the Freedom
TM
CPAP Battery; therefore, the use of the 150W sine wave power inverter is required in conjunction with battery.
DO
NOT connect a ResMed S8 device to the battery without using the sine wave power inverter as doing so will
cause irreversible damage to the PAP device.
REQUIRED COMPONENTS
Freedom
TM
CPAP Battery Kit
150W Sine Wave Power Inverter (inverter)
CONNECTION INSTRUCTIONS
Plug the DC input cord into the DC OUT jack of the battery.
Plug the inverter into the DC input cord.
Plug the AC power cord of the PAP device into the inverter.
Turn the PAP device on and it should begin functioning.
The digital display screen will show the charge level of the battery. You may press the charge level indicator
button to illuminate this screen. It will stay illuminated for a few seconds at a time.
When not in use disconnect all devices from the battery thus allowing the battery to completely shut down.

The inverter can also be used to charge the battery in a vehicle (vehicle does not need to be running) and to power/charge
other small electronic devices with the
b
attery. The inverter is not proprietary to the
Freedom
TM
CPAP Battery and can be
used with other external batteries.
