The trailer end of this cord is connected to an
electrical box on the trailer, sometimes referred to
as a “motor base.” This box connects to circuit
breakers and/or fuses and includes a power
converter to change the shore power (usually 120
volts alternating current) into 12 volts direct current.
WARNING
Shore power poses a risk of death due to
electrocution.
Always use a grounded connection.
Never connect to an ungrounded source of
shore power.
Never remove the “third prong” from the
shore power plug.
WARNING
Risk of fire.
Connect only to source of correct voltage.
Do not overload electrical circuits.
Do not use an extension cord to connect to
shore power.
Replace fuses with like rating.
Never use a two-conductor extension cord, or any
cord that does not assure appropriate and adequate
ground continuity. Use a 30-amp RV extension cord
with a maximum length of 25’. Never plug the 120-volt
cord into an ungrounded receptacle.
POWER DISTRIBUTION CENTER
The power distribution center consists of 120-volt
AC, 12-volt DC panels and the power converter. The
120-volt AC panel board containing a 30-amp main
breaker and 15 and 20- amp branch circuit breakers.
These breakers interrupt the power if the rated cur-
rent is exceeded. If a breaker trips repeatedly, reduce
the load on that circuit and have the system checked
by your Lance Trailer Dealer.
Switching from 120-volt AC power to 12-volt DC
power is automatic when the power cord is plugged
in or the generator is on. This powers the 12-volt
panel board and the connected circuits are protected
by the installed fuses. Battery charging is automatic
when using 120-volt AC power. There are two 30 amp
ATC fuses located in the front of the converter. These
fuses protect the power converter from accidental
shorting of the power cables at the battery or reverse
polarity caused by accidental cross connecting the
battery. Remember
BLACK is POSITIVE (+) , WHITE
is NEGATIVE (-) .
The power converter has a cooling fan that will run at
appropriate times to cool the converter.
NOTE: Should the converter shutdown during normal
operation, heat may be the cause. The converter has
a built-in automatic-reset thermal breaker that will
reset after a cooling off period. If this occurs
frequently, your dealer or qualified personnel should
correct the problem. Be sure not to store items in
front of the vent openings.
