The DC/DC Converter 24V/90W allows you to operate an S9
device including an H5i and ClimateLine from a 12V or 24V DC
power source in a car, boat, or other vehicle equipped with
a suitable battery. Consult your equipment supplier for more
information about this accessory.
CAUTIONS
• Only use the converter when connecting to a 12V or 24V
DC supply.
• Do not connect an S9 device to a 12V or 24V DC power
source while the DC power source is being charged from
AC mains.
• The converter must only be used with S9 devices to ensure
proper performance of the device.
• The converter is intended for use on 12V or 24V negative
ground systems (where the negative terminal of the battery
is grounded). Using it on a 12V or 24V positive ground
system may damage the S9 device and the vehicle's
electrical system. If you are unsure whether you have
a negative ground system, consult the power source's
manual.
• Do not leave the converter connected to the power source
when the S9 device is not in use, as this may discharge the
battery over time.
• Make sure the converter is not covered during use, to avoid
damaging the device.
• You must have an electrical system in good condition.
Have it checked by an auto electrician if in doubt.
• The converter is not intended for use on an aircraft.
Using the converter
Refer to illustration A.
1. Before connecting the converter, ensure the switch (1) is off.
2. Position the converter on a level surface, with the ResMed logo
facing up.
3. Plug the connector end (2) of the converter into the DC input
socket (5) on the S9 device.
Connecting via a cigarette lighter
1. Remove the cigarette lighter from the vehicle socket.
2. Plug the cigarette lighter adaptor plug (3) on the converter into
the vehicle cigarette lighter socket.
3. The light (4) on the converter will glow green when the
connection is made and the switch is on. Your S9 device should
then power on.
The light will flash continuously if the connection is not made,
or if the device is in standby mode or power save mode when
4 the connection is made. If the battery is low, the light will turn
amber. If the light does not operate, check that the switch on
the cigarette lighter adaptor plug is on.
Notes:
• Some vehicles require the ignition key to be turned to the
"accessories" position to provide power to the cigarette
lighter socket.
• If you connect your S9 device to a powered converter, the
converter may power down. To resume power, turn your
converter off and on again via the switch on the cigarette
lighter adaptor plug.
• If the battery AND your vehicle are not in good condition, there
may not be enough reserve left in the battery to start the
vehicle after use.
• ResMed does not recommend frequent use of the standard
automotive cigarette socket to power your S9 device. A
standard vehicle battery is not optimized for frequent heavy
discharges. Contact ResMed Technical Services for further
information and recommendations.
• There are no user-serviceable parts inside the converter.
• If the converter cuts power to your S9 device when starting
your vehicle, disconnect the converter from the vehicle, wait a
few seconds, and then reconnect it.
Cleaning
If necessary, wipe the outside of the converter with a clean,
damp cloth.
