Blue Sea 7649 Mini Add-A-Battery System

m-ACR Mounting ? To avoid corrosion to connecting wires and terminals, mount in a dry and protected location if possible. Avoid locations directly above the battery banks. m-ACR Electrical Connections ? The wiring diagrams illustrated on the back page represent common installations and are not meant to be a guide for wiring a specific vessel. ? The 7601 m-ACR is not intended to carry starting currents. Use a battery switching system with a combine batteries/parallel function if batteries may need to be combined for emergency starting. Caution: Disconnect battery connections before beginning the installation. m-ACR Voltage Sensing ? The 7601 m-ACR will sense a charge being applied to either battery bank. * Larger wire sizes may be required to minimize voltage drop in long wire runs.

Connect one battery bank positive to one of the 1/4?-20 studs. ? Connect the other battery bank positive to the other 1/4?-20 stud. ? Both positive connections should be made through appropriately sized circuit protection to meet ABYC recommendations. See ?Wire Size and Fuse Rating? chart, above, for suggested fuse ratings. ? Connect the quick connect terminal marked GND (ground) to the DC system ground through a 10A in-line fuse to prevent fault currents from flowing in this wire. m-ACR optional connection: To enable start isolation: ? Connect a wire from the quick connect terminal marked SI (starting isolation) to the terminal or wire running from the start key switch to the starter solenoid (see back for wiring diagram). This connection can be made at the start key switch or at the starter solenoid, but must be to the line that is positive only when cranking. Connection to a line that
