Engine Starting Standard Blue Sea Systems’ battery switches, in addition to being tested to UL 1107, are also tested to the Engine Starting Standard by a United States Coast Guard certifi ed Nationally Recognized Testing Laboratory. The Standard rates battery switches based on testing under very diffi cult starting conditions. DC Battery Switch Panels PN 8280 and 8370 provide an electrical system in which the main House circuit and the engine Start circuit are isolated from each other. Battery isolation protects the Start battery from being discharged from the many House loads like refrigerators, stereos, and lights, preserving it for starting the engine. Battery isolation also protects sensitive electronics from voltage spikes and sags that may occur during engine starting. Battery switch operation is simplifi ed because the three battery switches are ON/OFF. The engine and house battery switches are turned ON when the boat is boarded, and OFF when the boat is not in use. In an emergency requiring that both battery banks are combined—e.g., a discharged start battery—the operator switches the Emergency Parallel switch to the ON position; this combines both Engine and House battery banks. Charging of two battery banks can be automated by adding an Automatic Charge Relay (PN 7600 or PN 9112) to the system. This combination cre- ates a complete battery management system of isolated battery circuits, emergency combine function, and automated charge management. 1. Disconnect all DC power To eliminate the possibility of a short circuit while installing the panel, disconnect the main positive cable from all batteries. 2. Select mounting location and cut opening Select a mounting location that is protected from water on the panel front and back. Using the panel template provided, make a cut out in the mounting surface where the panel is to be mounted. Do not fasten the panel to the mounting surface. 3. Electrical Connections Battery cable terminals must be attached under battery switch stud nut and lock washer. The electrical connection illustration is general in nature and is not meant to be a guide for the wiring of any specifi c vessel. There is a wide range of wiring confi gurations possible. Consult your marine electrical professional for the wiring system applicable to your boat. Make appropriate adjustments to the wiring diagram to suit your specifi c installation and equipment. Fusing may be appropriate in several of the lines depending on the proximity of components, conductor sheathing, and the conductivity of the surrounding structure. Consult the Wire Sizing Chart to determine the appropriate wire sizes. 4. Apply Labels and Mount Panel Apply a label to each of the circuits from the label sheet provided. Use the panel mounting screws supplied with the panel to secure the panel to the mounting surface. Additional labels are available from Blue Sea Systems.
