Blue Sea Systems 7611 Manuale utente
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.
Electrical Connections
• The wiring diagrams illustrated on the back page represent common installations and are not meant to
beaguideforwiringaspecicvehicle.
• The 7611 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.
Use the Wire Size and Fuse Ratings chart on page 2 to select the appropriate wire sizes to prevent
overheating the ACR.
Voltage Sensing
• The 7611 ACR will sense charging sources available on either battery bank.
Minimum connections for operation:
• Connect one battery bank to stud terminal A.
• Connect the other battery bank to stud terminal B.
• Connect the quick connect terminal marked Ground to the DC system ground through
aoneampin-linefusetopreventfaultcurrentsfromowinginthiswire.

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.
*BecausetheBatteryLink™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.
*ItisrecommendedthattheACRbeconnecteddirectlytoyourbatterypositiveterminals
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.
