NORTHWOOD 2004 series Owner's Manual - 120-Volt Ac System

will not be drained from the batteries–you need to turn the key on to operate with 12-volt power from
the battery source.
The 12-v olt kill switch should be used to avoid 12-volt drain if the unit is stored even for a short time
period.
BATTERY CHARGING: Normally the battery will be kept charged by either the truck charging
system while on the road or by the AC/DC power converter when plugged into AC service.
IMPORTANT NOTE: Always leave home with a full charge on your battery(s). A slow trickle charge
is best for long battery life. It requires at least 52 hours to fully charge an RV battery on a trickle
charger. Once your battery(s) is fully charged, your power convertor will maintain the battery(s) to full
peak while your unit is plugged into 120-volt shore power and your truck charging system will keep
the battery(s) at full peak while traveling.
Do not smoke near batteries being charged or which have been recently charged. Please note that
batteries are being charged while you drive and while you are connected to 120-volt AC power
through the power center/charger circuit.
Check and adjust the electrolyte level before charging. Fill each cell to the indicator with distilled
water.
120-VOLT AC SYSTEM
: This system provides grounded electrical service for appliances
such as the air conditioner, TV, microwave oven, 110-volt outlets, etc. The 120-volt system also
provides a power source for the power center.
The camper is equipped with a heavy duty power supply cord. This power cord is located in the
power cord compartment with an access door located on the outside of the unit. One end of the
power cord is permanently connected to the main breaker box which is then connected to the
converter. The other end of this cord has a plug that can be connected to an external 120-volt AC
power outlet.
The breaker box (power center) is located on the inside of the unit. If a circuit breaker trips open a
circuit, you may be using too many portable appliances. Unplug all of the appliances and reset the
breaker. If the breaker trips off again, contact your servicing dealer or an electrician. Do not try to
use the circuit again before it is inspected. If the breaker remains on, plug in only a few of your
portable appliances at one time. The outlet receptacles only operate on 120-volt AC power.
IMPORTANT: Do not use a two-conductor extension cord or any cord or cable that does not assure
appropriate and adequate ground continuity.
THE POWER CENTER:
The power center will supply 12-volt requirements when your
camper is operating on 120 AC volts. Thus, you will not have to worry about running down the
battery. When you are plugged into 120-volt AC service, the power center automatically switches the
load from the battery to the power center. The onboard battery will gradually be brought up to a full
charge and maintained by the battery charger as long as 120-volt power is available.
