Before installing this unit to a recreational vehicle, a bus, or a truck, make sure the battery
voltage is appropriate for this unit to be used, otherwise, have a professionally installed
transformer to convert the output voltage to 12V.

disconnected before installation.
• To prevent short circuit in the wiring and damaging to this unit, secure all wirings with cable
