Recommended Installation Diagram
* This installation diagram shows a typical application only. Your application may differ.
For further information, please go to www.bluesea.com and navigate to
Resources/Application Briefs and Technical Briefs.
* Because the BatteryLink™ ACR is Dual Sensing, terminals A and B are interchangeable.
ACR function will not be affected by reversal of the starting and house batteries versus
the diagram.
* It is recommended that the ACR be connected directly to your battery positive terminals
through appropriately sized fuses. Connecting in a different location such as a battery
switch may affect accuracy because of voltage drop along current carrying conductors.
* If you are not knowledgeable about electrical systems, please consult an electrical
professional for help with installation.
