Wiring Diagram
The following wiring diagram will be referenced in the next section.

Installation

• Before doing anything, disconnect all wires from the negative side of the battery.
• Cut the negative cable for the battery and crimp on new ring terminals. Alternatively, use a new wire of appropriate gauge to carry the full current demand of your system.
• Install the shunt as shown in the wiring diagram above. Note: The negative terminal of the battery must connect directly to the“B-" side of the shunt, and there should be no other connections to the negative terminal of the battery for accurate measurements.
• Use the B+ wire included in the package to connect the B+ terminal of the shunt to the positive side of the battery. Note: Do not stack smaller terminals under large ones.
• Connect the shunt to the remote display using the included shielded cable.

Mounting the Remote Display

• Plan the location of your remote display and keep in mind there is a cable that needs to route all the way to the shunt.
• Drill a hole in the center of the planned location and use the jig saw to cut a hole according to the following picture.
• Connect the shielded cable to the shunt and route it such that you can bring it through the hole.
• Connect the shielded cable to the remote and snap the remote into place.

• Hold the "Ok" button for 3 seconds to enter the settings screen. The up and down arrows are used to navigate as well as change parameters. The "Ok" and "<<" button are used to enter and exit a setting.
• Set the "CAP" setting to match the capacity of your battery or battery bank.
• Optionally set the "HIGH V" and "LOW V" values to the voltages at which you want remaining capacity/percentage to reset to 100% and 0% respectively.
• Alarm is the minimum Ah value that will trigger an audible alarm.
• Once all of these settings are complete, hit "<<" and your BMK is set up.
