Si acr wiring diagram. Si acr automatic charging relay with start isolation. An acr senses when the voltage of either of the batteries rises to a level indicating that a charge source is active 130v for 2 minutes. The wiring diagrams illustrated on the back page represent common installations and are not meant to be a guide for wiring a specific vessel. Disconnect battery connections before beginning the installation. An acr is intended to keep a load from discharging both of the batteries. How does an acr work.
Si acr automatically combines batteries during charging isolates batteries when discharging and when starting engines. The 7610 acr is not intended to carry starting currents. The dual circuit plus battery switch simplifies the switching of two batteries to off or on while still providing battery isolation between the engine and auxiliary battery.
