The Multiplus temperature sensor must be attached to the main negative battery terminal (not the main positive terminal).
BMV B2 cable must be attached to the mid-point of the battery bank if used to measure mid-point voltage deviation (not the main negative terminal).
Alternatively, if you purchase the additional BMV temperature sensor then that is mounted on the main positive terminal and connects to both B1 & B2. Also note that the BMV and Multiplus temperature sensor is a different PN.
If your not totally sure what your doing get help from an experienced/qualified installer. You don't want to blow up your new equipment because of a simple oversight, or worse have an unsafe installation. There is a lot more to an installation that what plugs into what.
