Blue sea automatic charging relay wiring diagram. Disconnect battery connections before. Acrs or automatic charging relays are automatic switches that close when the voltage on one of the batteries rises to a level normally 132v to 137v indicating the battery is connected to a charge source and is partially or fully charged. The following basic wiring diagrams show how batteries battery switches and automatic charging relays are wired together from a simple single battery single engine configuration to a two engine one generator and four battery bank system.

Use the blue sea systems panel wizard to design and order a custom 360 panel. Your application may differ. Automatic charging relays. Charge management devices allow two battery banks to be charged from a single source such as an alternator but keep batteries isolated when not charging.

Charge management devices allow two battery banks to be charged from a single source such as an alternator but keep batteries isolated when not charging. The 7611 acr is not intended to carry starting currents. For more detailed wiring guidelines please consult a qualified marine electrician or one of the many books available on the subject. Use a battery switching system with a combine batteriesparallel function if batteries may need to be combined for emergency starting.
