* Note: Unlike household wiring, the neutral (N) and ground (G) are only connected
together at the SOURCE of power, either inverter or shore/station power. The
TruePower Plus transfer switch maintains this wiring scheme automatically.

2) DEDICATED APPLIANCE - This scenario is becoming popular with items like air conditioning
units and refrigerators where the load of the appliance and the rating of the inverter are matched.
With this type of installation, the inverter is dedicated to only one load, whether in inverter or
pass-through mode.
Advantages - With this installation type there is never an issue with overloading of the inverter capacity.

STOP!
BEFORE INSTALLING YOUR INVERTER READ AND FOLLOW THE BELOW CHECKLIST:
Begin with the power switch and main shore/station power breaker in the off position.
Ensure that all overcurrent protection (e.g. fuses and/or circuit breakers) are ready for use, not blown or tripped.
Use great care to ensure the polarity of the DC connections are correct or damage will result to your inverter.
Verify all connections are tight, corrosion free and of good integrity.
DO NOT OPERATE THIS UNIT WITHOUT THE EARTH GROUND CONNECTION ATTACHED.
The earth conductor is permitted to be 1 common size smaller than the DC positive (+) conductor
(Example: DC += 2 AWG, Earth = 4 AWG)
12 Volt DC Battery Source - On Board Solutions minimum recommended battery or battery bank
is 200 Ahr. Batteries can be a single battery or multiple batteries in parallel. Batteries connected
in parallel boost amp hours while maintaining voltage.
Tapping each battery as shown balances the load of the battery.
