and a more highly rated inverter.
No power will be supplied to your humidifier if
your VPAP Auto is connected to a converter.
How do I connect my VPAP Auto
to the battery?
Connect the inverter or converter to a battery using
the Battery Adapter Cable, then connect your VPAP
Auto to the inverter/converter. Be careful to match
the polarity (+ and -) symbols correctly between
the adapter cable and the battery.
Which inverter (or UPS) should I use?
The type of inverter that you need depends on
your VPAP Auto setup. Table A lists the minimum
specifications for an inverter/UPS.
When purchasing an inverter please ensure that:
• the inverter is certified by an accredited
certification body (eg, CE, UL)
• the inverter’s case temperature is specified as
less than 50ºC at an ambient temperature of 35ºC.
Can I connect my VPAP Auto
to a vehicle or boat battery?
Yes, but standard automotive batteries are
generally unsuitable for therapy requirements;
continual use of an automotive battery can
shorten its lifespan and the therapy delivered
may not be adequate.
If you are using your VPAP Auto in, or close to, a
vehicle, you should consider a dual-battery set up.
Consult an automotive or marine electrician for
details about installing a dual-battery system.
Most converters and inverters are supplied with a
plug for an automobile cigarette lighter socket.
