Fluctuations of temperature or power usage are
automatically monitored.

A sensor eliminates damage to the converter if the
terminals are "short circuited."
NOTICE
If the coach batteries cables are connected
backwards, the two 40 amp fuses (11), located behind
the electrical panel will blow. If this occurs, connect
the battery correctly before replacing the fuses.
If your appliances fail to function, check these fuses
located behind the panel door.
The converter turns on when 120 volt AC power is

normal 12 volt DC power requirements will run down
the coach batteries.
