Battery Disconnect Switch; Inverter; Power Converter - Airstream CLASSIC 2021 Owner's Manual

Battery Disconnect Switch

The battery disconnect is operated by using either the
main Multiplex Control Panel or by pressing the
button on the Multiplex panel located at the
entry door� You can also operate this function through
the Airstream Smart RV Control app� The disconnect
switch is used to separate the batteries from the 12-volt
distribution panel�
When the trailer is plugged into an external AC power
source the 12-volt distribution panel will receive power
from the converter and the batteries will be charged
through the converter charging system regardless of if
the battery switch is in the ON/OFF position�
If the trailer is NOT plugged into an external AC power
source and the switch is turned to OFF the batteries
are disconnected and the 12-volt fuse panel will
not receive power from the converter or batteries�
The converter will not charge the batteries when
no shoreline power is present� The OFF position
is intended for storage of the trailer or when power
conservation is desired�
The charge in the 12-volt batteries can be replenished,
depending on the tow vehicle, from the tow vehicle
alternator through the 7-way cord. This charge will flow
to the batteries regardless of the battery disconnect
switch position� Likewise, if ON or OFF, the solar panel
will still charge the batteries�
NOTE
Even with the battery disconnect switch in the
"OFF" position the LP detector will have a small
parasitic draw.
NOTE
A 24-Hr circuit provides power to the router
even when the battery disconnect is in the "Off"
position. The circuit requres 5 mA of 12-Volt Power.

Inverter

The 1,000 Watt inverter converts 12-volt electricity from
your batteries into 120-volt power� Operation of the
inverter is controlled from the main touch screen on
the first favorites page. The inverter powers the TV's/
Entertainment devices and additional labeled 120-volt
receptacles�
NOTE
Overloading the inverter will cause an automatic
shutoff to activate. Removing the load will allow
the inverter to reset.

Power Converter

The power converter is located below the wardrobe
behind the false panel�
The converter transforms 120-volt AC into 12-volt
DC� The converter/charging system is the interior low
voltage electrical system that enables you to use the
interior lights, fans, pumps, and 12-volt appliances,
whether operating on self-contained battery power or
120-volt city power� The 12-volt light bulbs give off the
same light as regular household bulbs, so that when
operating on self-contained battery power, everything
works normally except the 120-volt convenience
outlets and 120-volt appliances� The converter system
is designed to maintain constant output voltages
regardless of the variances that occur in city power
systems�
The converter is energized only when the trailer is
hooked up to external AC power�
To test the converter, observe the following:
• Confirm 120-volt power is going into converter.
• Disconnect the 12+ wire from the master switch�
• Using a voltmeter, check voltage output between
heavy gauge positive and negative wires coming out
of converter�
• The voltage should be within 13�6 and 14�0 volts�
(The meter of the tester should be calibrated
periodically�)
• If converter is not within these voltages, have it
serviced by a qualified technician or replace it.
One of these wires is not spliced onto a wire of the
same color� It is the backup wire that is yellow in the
cable and black in the harness�
A label on the inside of the converter door lists the
circuits and what each fuse powers�
