The BC300 External Shunt has two mounting terminals. Using these terminals, the BC300 External Shunt is wired in series with the negative terminal of the battery being monitored and the negative battery loads.
The ‘+’ flying lead provides a connection to the positive terminal of the battery to power the BC300 External Shunt. This lead is also used to measure the battery temperature and voltage and must be directly connected to the positive terminal of the battery.
You must ensure that all loads connected to the battery are disconnected or turned off before beginning the installation to avoid sparks being generated.
