Hello, how to understand the "It is essential the negative battery terminal between the units is always connected. A fuse or circuit breaker is not allowed" in the Multi II Manual? The interconnection between the units is meant? The BMS in error case disconnects the minus pole of the battery by N-MOSFETs, there is no way to do it in other way. And the DC terminals of the Multis see no difference (except of the stray capacitance) which pole is disconnected. Is it correct to earth the plus pole of the battery and insert the fuse and the DC switch into the minus line which can be interrupted by the BMS anyway? Thanks.
