12-Volt Power Circuits
The current in the converter system is 12 volts direct current (12 VDC) negative grounded. Power sources that supply 12-VDC current to the system are as follows:
- Main charge line from tow vehicle
- Trailer batteries
- Converter
The power sources listed above are all electrically connected to the 12-volt distribution fuse panel that distributes current to interior branch circuits. The circuits provide power to operate all 12-volt DC lights, pumps, motors, and appliances.
The power converter is a solid-state electronic power supply and is maintenance-free. It is so self-sufficient and quiet that you will probably not know it is working except for the fact that your batteries are always charged, and your 12-volt lights and appliances always work.
If any 12-volt appliance fails to operate, first check your 12-volt distribution fuse block, located behind the decorative front door in the front right-hand corner of the converter, and inspect all fuses. If a fuse is opened or blown, replace it with the same size fuse (never install a larger fuse). If the fuse opens again, have an electrician or certified RV technician locate the circuit trouble. Replace blown fuses only with the same type and amperage size previously used.
If the power converter is not working, first confirm the RV supply or shoreline cord is plugged in to a live circuit. Then check all the 120-volt breakers in your RV distribution panel to make sure they are on. If the breaker is tripped, follow the instructions to reset the breakers. If the breaker trips again, consult an electrician or certified RV technician.
Converter Operation
The power converter is designed to supply the nominal 12-volt-filtered DC power for all 12-volt-operated devices encountered in RV service. Although the converter is an excellent battery charger, the converter does not require a battery to be connected to it for proper operation.
NOTE
When installing a battery(ies), always observe polarity. Connecting a battery in reverse polarity will blow the power converter main fuses located on the 12-volt DC distribution fuse block.
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 converter’s 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.
Automatic Micro-Controller Operation
The power converters 3-stage switch mode is fully automatic. The converter senses which mode it needs to be in by checking the condition of the battery.
The three modes include:
Absorption Mode: During this mode the converter output is in the 13.6 VDC range. This is the mode that the converter will function at normally. This mode provides the 12 VDC and the current required by the trailer.
Bulk Mode: In this mode, the output voltage of the converter will switch to 14.4 VDC range for a maximum of four hours. If the converter cycles between
“Absorption and Bulk modes”, there could be a shorted battery cell or other issues.
Float Mode: If the trailer has not been used for a period of time and the shore power has been left plugged in, the converter will automatically go into float mode with a voltage of 13.2. When the converter senses a demand, by turning on lights, the converter automatically returns to absorption mode.
120-Volt Electrical System
City Power
When your trailer is hooked up to external AC power, the converter system automatically charges the trailer batteries regardless of the battery disconnect switch 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 external AC power, 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. 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 between the wheels and above the wheel well.
All wire, components, and wiring methods conform to federal and state requirements.
Converter
The converter system is a transformer designed to maintain constant output voltages regardless of the variances that occur in city power systems. The design eliminates the need for complex electronic sensing systems to charge the batteries, minimizing the possibility of failures and greatly increasing its overall reliability.
In some older parks and other locations where three-pronged outlets are not available, certain precautions to ensure proper grounding and polarity must be taken. These precautions are listed below:
- Attach the three-pronged plug to a two-pronged adapter. The third conductor line of this adapter has a short wire lead that must be grounded.
- For proper grounding, connect the short ground lead to a grounded outlet box or to a cold water pipe. When no water pipe is available, drive a metal rod two feet into the ground and attach the ground lug to it, thus providing the unit with proper grounding.
NOTE
When the three-pronged plug can be used, there will be no problems with proper polarity or grounding with a properly wired shoreline outlet.
NOTE
When operating with city power, make very certain that the service is 120-volt, not 240-volt.
To operate self-contained, simply disconnect the power supply cable.
Ground Fault Circuit Interrupter (GFCI)
Most states require trailers with exterior 120-volt receptacles and receptacles close to a water sources, such as a faucet, to have a ground fault-circuit interrupter. When properly installed, the GFCI circuit breaker provides reliable overload and short-circuit protection, plus protection from ground faults that might result from contact with a HOT load wire and ground.
WARNING
The GFCI circuit breaker will NOT reduce shock hazard if contact is made between a HOT load wire and a neutral wire or two HOT load wires.
Each GFCI circuit breaker is calibrated to trip with a ground current of 5 milliamperes or more. Since most people can feel as little as 2 milliamperes, a distinct shock may be felt if the need for protection exists. However, the shock should be of such short duration that the effects would be reduced to less than the normally dangerous level. However, persons with acute heart problems or other conditions that can make a person particularly susceptible to electric shock may still be seriously injured. While the GFCI circuit breaker affords a high degree of protection, there is no substitute for the knowledge that electricity can be dangerous when carelessly handled or used without reasonable caution.
WARNING
The GFCI circuit breaker provides protection only to the circuit to which it is connected. It does NOT provide protection to any other circuit.
GFCI Breaker Test
Perform this test on the GFI circuit breaker each month and record the date.
- With handle A in “ON” position, press PUSH TO TEST button B.
- Handle A should move to TRIP position, indicating that GFCI breaker has opened the circuit.
- To restore power move handle A to “OFF” and then to “ON“.
If the device remains on when the Test button is pushed, the GFCI is not working properly or has been incorrectly installed (wired improperly). If your GFCI is not working properly, call a qualified, certified electrician who can assess the situation, rewire the GFCI if necessary, or replace the unit.
NOTE
All GFCI breakers implement an auto self-test function, however, Airstream recommends a manual test be conducted every month.
- With handle A in “ON” position, press PUSH TO TEST button B.
- Handle A should move to TRIP position, indicating that GFCI breaker has opened the circuit.
- To restore power move handle A to “OFF” and then to “ON“.
