Power Supply
Provide AC power for the battery charger (integral to
the VSC controller) and optional carburetor heater.
The power requirements are shown in Figure 1-10.
The power source must be GFCI protected.
power to the accessories must be available at all
times, i.e. the circuit must be powered by the primary
source and backed up by the generator.
Be sure to disconnect power at the distribution panel
before making the connections. Connect power leads
to the utility power connection points on the terminal
block shown in Figure 1-9. See Section 1.8.3 and the
wiring diagrams in Section 2 for connection details.

For longer cable runs, use Belden #8762 or equivalent
20 AWG shielded, twisted-pair cable with 2 conductors
for the A and B connections, and use 12-14 AWG wire
for the COM and PWR connections. See Figure 1-11
for the maximum cable lengths.
