Installation Diagrams
WARNING - AC Installations have the potential to cause serious injury or death,
installations should be performed by an ABYC Certified Electrical Technician to ensure
a safe and trouble free installation.
Depending on the appliances & loads that are intended to be powered by the TruePower
Combi, there are essentially 3 installation options:
1) SPLIT BUS – This option allows only certain circuits to be energized by the
TruePower Combi. There are several points to make a note of in the following
drawing provided from ABYC found in A-31 Battery Chargers & Inverters:
a. The TruePower Combi acts as a pass through, the AC inputs are fed
from ANY AC power source, Shore or Generator. The input to the
TruePower Combi must be tapped from power AFTER any installed
transfer switch.
b. In this scenario, the complete Main AC Panel WOULD NOT be powered
by the TruePower Combi. Either an additional AC Subpanel can be
installed (constantly powered by the Shore/Generator pass-through or,
when in Invert mode, exclusively powered by the TruePower Combi) OR
the existing AC Panelboard bus can be split into essentially 2 parts with
only 1 part HOT during invert mode.
Advantages – The split bus scenario ensures that the TruePower Combi is not overloaded
by installed loads. (of course, plugged-in portable loads may exceed the wattage rating
if not controlled)
