Description  
The CL-Series BatteryLink™ ACR connected into your boat’s electrical system  
provides automatic control for charging dual battery banks. The ACR has two  
parts:  
• A relay - a switch that is activated by an electrically powered magnetic coil.  
• An electronic circuit that senses the voltage level of the boat’s batteries  
and signals the relay to switch:  
- Closed when voltage is high (the ACR’s COMBINE voltage)  
- Open when voltage is lower (the ACR’s UNDERVOLTAGE voltage)  
When the voltage level of the battery bank being charged reaches a certain level,  
both battery banks are automatically connected and charged.

Installation Instructions  
Mounting  
• Select a mounting location near the battery banks or the battery switch.  
• Choose a cool, dry, and well-ventilated location if possible. The CL-Series  
BatteryLink™ ACR may become very warm when operating at full current  
capacity or in current limiting mode.  
• Avoid locations directly above batteries where corrosive fumes may be present.  
• Do not mount directly to a conductive surface because of the proximity of  
the mounting screws to the main electrical terminals.  
• Mount the relay securely with #8 or M4 screws.  
Wiring  
Use interconnecting wiring that provides acceptable voltage drops at the intended  
charging currents. Wiring should have at least 60 Amp current-carrying capacity  
to be compatible with the current limiting feature of the CL-Series BatteryLink™  
ACR. Use:  
• At least 8 AWG wire for a connection length of 6 feet or less  
• At least 6 AWG wire or larger, according to voltage drop calculations, for  
runs longer than 6 feet  
• Gray dashed [2] and [4] lines indicate optional connections  
• Gray solid [1] line indicates a recommended but not required connection  
Typical Conguration - Sense One Battery Bank  
ABYC E-11 recommends circuit protection within 7 inches of each battery  
connection or source of power. Circuit protection may be as far as 40 inches from  
a source of power other than a battery, or 72 inches from a battery if the wiring is  
protected by a sheath or enclosure.  
To sense the voltage level of the battery bank connected to your boat’s  
charging source:  
• Connect Terminal A to the battery bank connected to the charging source.  
• Connect Terminal B to the battery bank not connected to the charging source.  
• Connect Terminal 3 to the main negative bus or the negative terminal of the  
nearest battery, through a 10-15 amp in-line fuse, to prevent fault current  
from owing in this wire.  
To avoid nuisance tripping or fuse blowing, the wire should be:  
• Sized to carry the full capacity of the charging source  
• Protected by a time-delay fuse (e.g., Bussmann TFC rated 75A or larger)  
or thermal circuit breaker (e.g., Bussmann 187 rated 150A).  
Current-limiting  
Sense Both Battery Banks  
The current-limiting feature of the CL-Series BatteryLink™ ACR prevents  
excessive current from owing through it and can be treated as a self-limiting  
protective element. The current handling capacity is shown in this table. Time  
delay allows brief currents up to 150 Amps.  
When charging sources are attached to both battery banks, the CL-Series  
BatteryLink™ ACR can be connected to sense the voltage levels of both battery  
banks. Use this conguration, for example, when the alternator is connected to  
one battery bank, and the battery charger is connected to the other battery bank.  
Time  
Current Rating  
60 Amperes  
To sense both batteries banks:  
• Connect Terminal 1 to Terminal B with a jumper wire.  
Continuous  
7 Minute  
2 Minute  
Conguring the CL-Series BatteryLink™ ACR to sense both battery banks also  
establishes Undervoltage lockout. This lockout prevents automatic connection of  
both battery banks if the second battery bank is discharged below 4 volts. When  
the voltage levels of the battery banks are considerably different, they should not  
be connected -- the current through the CL-Series BatteryLink™ ACR may be  
high enough to fuse the internal relay.

120 Amperes  
Electrical Connections  
The wiring conguration below represents a common installation but is not meant  
to be a guide for any specic vessel. Consult a marine electrical professional for  
a wiring conguration applicable to your boat.  
If the voltage drop in the line connected from the battery bank to Terminal B is  
expected to be less than 3%, connecting Terminal 1 to Terminal B with a short  
jumper is suitable. If voltage drop is expected to be more than 3%, for example,  
when connecting widely separated batteries, mount the CL-Series BatteryLink™  
ACR near the battery bank connected to Terminal A and use a sensing wire from  
terminal 1 to the battery bank connected to Terminal B. The remote sensing wire  
carries less than 0.2A when the relay is closed so this conductor can be 16 AWG  
and should be protected against faults with a suitable fuse (any value between 2  
and 20 Amps) at the battery connection.  
Disconnect the positive battery connections before beginning the installation. If  
there is a possibility of tools causing a short to grounded metal or conductors,  
disconnect the negative terminals before disconnecting the positive terminals.
