120-VOLT SYSTEM
Power Supply
The ALTO converter/charger system enables you to use the lights and appliances whether
operating on self-contained battery power, or hooked up to 120-volt 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 for the 120-volt convenience outlets and 120-
volt appliances.
When your trailer is connected to 120-volt AC, the converter system automatically charges the
trailer battery and, if the 7-way connector is hooked up to the tow vehicle, the converter will
recharge the tow vehicle battery as well. The speed and degree of charge depend 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, if it is available, keep your trailer hooked up to a
120-volt power supply.
The converter system is designed to maintain constant output voltages regardless of the variances
that occur in city power systems. The transformer design eliminates the need for complex
electronic sensing systems to charge the battery, minimizing the possibility of failures and greatly
increasing its overall reliability.
The 120-volt breakers are located in the centre under the front table (photo H-2.2).
While you are connected to the 120-volt receptacle, the wiring is protected by circuit breakers in
the breaker panel. In the event of a failure of a 120-volt circuit, check your circuit breakers first.
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. If lessening the load does not solve the
problem consult an ALTO Service Center.
The 120-volt electrical system provides power to operate the air conditioner (optional), the
microwave (optional), the electric water heater (Truma), the electrical heating (Truma), the
converter and the 120-volt receptacles for portable appliances. The power is carried through the
120-volt yellow power flexible cord to the 120-volt distribution panel, and then is distributed to
each appliance or receptacle.
All wires, components, and wiring methods conform to federal, provincial and state
requirements.
The breaker panel in your trailer (photo H-2) bears a label to designate the circuits specific to the
trailer.
To provide better protection, Safari Condo installs ground-fault interrupters on several outlets.
