Extra Low Voltage (12Vdc) Power System
Distribution Switchboard Control Panel
Located in overhead cabinets this panel is the primary location for the 12Vdc power system. It houses the main rotary isolator
switch for all non-constant 12Vdc loads on the battery, rocker switches to control the various circuits throughout the caravan
and mini circuit breakers protecting these circuits. It also contains a legend to identify what electrical components are part of
which circuit and is where you will find the Renogy ONE core energy monitoring and analysis display screen.
12V Isolator Switch
• Rotate the red rotary switch to the ON position to allow 12V loads to operate. These loads draw power directly from the
battery system.
• Rotate the switch to the OFF position to isolate these loads, preventing power draw from the battery system.
• Rotate the switch an additional ¼ turn past the OFF position to enable the lockout function. The switch knob can be
removed by pulling it away from the panel for added lockout isolation, if required.
While the 12V isolator switch is in the OFF position, the battery may still be charged , and the
inverter may still be operational .
LED rocker switches
• Moving the switch upward activates the corresponding circuit, indicated by a red LED light on the switch.
