120-Volt AC Panel Board
The AC panel board section of the power converter
contains the 120 VAC branch circuit breakers for your
RV� One of the breakers controls the 120-volt power
to the 12-volt converter section� This breaker may also
control another branch circuit� Check the label next
to each breaker for what each branch circuit breaker
controls�
The 120-volt circuits may be turned on by setting their
breaker handle up to the ON position, or off by setting
the handle down to the OFF position� To reset the
tripped breaker, move the handle to OFF then ON�
The system incorporates GFCI breakers that implement
an auto self-test functionality� When turned off, these
breakers require external AC power to be present , or
the AC inverter enabled, before they can be turned
back on� If AC power is present from one of these two
sources, and the breaker refuses to stay on consult an
electrician or certified RV technician.
Converter Cooling System
The converters electronic fan cooling system is the key
to long life and trouble-free operation� The fan is never
on more than required to cool electronic components in
the converter� You may never hear the fan operate�
Inverter
The 1,000 Watt inverter converts 12-volt electricity
from your batteries into 120-volt power� The switch for
the inverter is located on the wall above the cook top�
The inverter powers the TV's and Blu-Ray player, as
well as, additional labeled 120-volt receptacles in the
bedroom, lounge, and below the dinette seat�
NOTE
Overloading the inverter will cause an automatic
shutoff to activate. Removing the load will allow the
inverter to reset.

120-Volt Electrical System
City Power
When your trailer is hooked up to external AC power,
the converter system automatically charges the trailer
batteries with the battery disconnect switch in the USE
(on) position and, if the 7-way cord is hooked up and
depending on your vehicle, your tow vehicle battery
as well� The speed and degree of charge depends on
how much power is used for lights and appliances, as
only the surplus goes to charging the battery� If you are
making an extended stay, then you should keep your
trailer hooked up to a 120-volt current if it is available�
While you are connected to the 120-volt receptacle, the
wiring is protected by circuit breakers in the breaker
panel� The circuit breaker panel for the 120-volt
system is located in the converter� Open the decorative
converter door below the pantry� In the event of a
failure of a 120-volt circuit, first check your trailer circuit
breakers and the breaker for the outlet into which your
trailer shoreline cord is plugged� If a breaker continues
to trip after you have reset it several times, your circuit
may be overloaded with appliances or there may be a
short in the circuit� Try lessening the load on the circuit�
Perhaps an electric griddle, hair dryer, or an electric
heater can be turned off� If that does not solve the
problem, consult an Airstream Service Center�
The 120-volt electrical system provides power to
operate the air conditioner, converter, and 120-volt
receptacles for portable appliances� The power is
carded through the 120-volt city power flexible cord to
the 120-volt distribution panel, and then is distributed
to each appliance or receptacle� Exterior outlets for
120-volts are located on the curbside exterior wall�
All wire, components, and wiring methods conform to
federal and state requirements�
