Mkove MK75 Battery Monitor – Instruction Manual
Installing the Battery Monitor
Disconnect the battery or battery bank from the system before installing the battery monitor.
Install the shunt into the battery system. The shunt can be installed into either the main positive or
negative (ground) cables connecting the battery. This is normally done by cutting the main battery
cable and then connecting each of the cut ends with cable lugs to the larger screw connectors on the
shunt.
On the Battery Monitor there are four connections which have to be made. All of these connections
can be made with thin wire, if desired, as none of these connections carry any significant current.
The overall length of the connections between the battery or battery bank to the battery monitor can
be quite long. We have tested lengths up to 50 meters without any loss of accuracy in the system
The four connections and the way to wire them is as follows;
•
BATT+ This should be connected to the positive terminal of the battery or battery bank. Ideally
this will be connected directly to the main terminal of the battery as this will cause the least
voltage drop when large currents are flowing into or out of the battery, and provide the most
accurate readings. If this is not possible choose a connection point which has a sturdy connection
as close as possible to the battery.
•
GND This should be connected to the ground or negative terminal of the battery or battery bank.
Like the BATT+ connection this should if possible be connected directly to the batteries main
terminal or to a sturdy connection point nearby.
•
SENS- This should be connected to the more negative of the two small screw terminals on the
shunt. The more negative end of the shunt is the end which is connected more closely to the
negative battery terminal. For example if the shunt is installed in the negative battery cable this
will be the end connected directly to the battery. If the SENS- and SENS+ plus wires are
connected in reverse the system will read current into or out of the battery in the incorrect
direction.
•
SENS+ This should be connected to the more positive of the two small screw terminals on the
shunt. The more positive end of the shunt is the end which is connected more closely to the
positive battery terminal. For example if the shunt is installed in the negative battery cable this
will the other end of the shunt from the cable which is connected directly to the battery. If the
SENS- and SENS+ plus wires are connected in reverse the system will read current into or out of
the battery in the incorrect direction.
If everything is correct reconnect the main battery or battery bank and ensure that the system is
operating correctly.
