3.5 Frequently Asked Questions
Q I want to install my remote at a distance from the main unit, but the cable supplied is only
2 metres, what can I do?
A You can buy a replacement cable from any good electronics specialist. The cable
must not exceed 10m in length and must be 6 Pin/6 Core RJ12 cable. The cable
must be crimped with a ‘twisted’ type connection. The way to easily tell this is
to hold both crimp connectors together as shown in the Figure 3.5.1. A ‘twisted’
connection will have the colours matched together.
NOTE: Ensure that the replacement cable has all 6 pins connected.
Q I have damaged my Power Cable and need to replace it, do I have to buy a special kind
of cable?
A A standard ‘kettle cord’ is suitable to replace this cable, as long as the cord meets
Australian Safety standards.
Q I have installed my BMS and all related components, it’s all working fi ne but I get a
negative current reading on the Summary screen, what have I done wrong?
A If you get a negative load current reading on the Summary screen, this generally
means that the Shunt + and Shunt – connections between the BMS and the Shunt
are around the wrong way. Swap the twisted wires at either the BMS or at the
Shunt.
Q I am running a load from my house battery, but it does not seem to register on the BMS
Remote, why can I not see this current draw?
A This can be caused by incorrect wiring of the shunt or if the load current is below
2Amps. All earth connections to the house battery, including the earth of the BMS
must pass through the Shunt. The BMS uses the Shunt to measure the currents
going into the battery and out of the battery, allowing the BMS to give more accurate
State of Charge and Time Remaining.
