DC WIRING OPTIONS
WARNING
For Installations using Battery Switches NOTE: No other DC loads should be connected to the common on the battery switch. This will prevent their operation directly from charger power when the battery switch is OFF.
DC Wiring #1 - Two Battery* System
Using Manual Battery Switch
This system is simple and effective, providing the user with the ability to choose between either battery for inverter use or charging.
When charging, the battery switch is typically left in the "All" or "Both" position so that both batteries are charged. When using the inverter, the inverter battery should be selected with the battery switch.
The inverter/charger's negative battery cable should be connected directly to the battery that will normally supply the inverter. A fuse should be installed in the positive cable within 18 inches of the battery. If the cables to the switch exceed 18 inches, each cable will require a fuse.
