Victron energy VE.Bus BMS Manuel page 7

4.2. Battery
In case of several batteries in parallel and or series configuration, the two M8 circular connector cord sets of each battery should
be connected in series (daisy chained).
Connect the two remaining cord sets to the BMS.
4.3. Powering up
In case of a DC only system: connect the battery plus. The system is now ready for use.
In case of a system with Multis, Quattros or inverters with VE.Bus:
4.3.1. After completion of the installation, disconnect the BMS from the VE.Bus and replace by a Victron Interface MK2 and a
computer.
4.3.2. Connect the battery plus.
4.3.2. Configure inverter/charger(s) or inverter(s) for parallel or three phase configuration if applicable.
Inverter/chargers: the AC Detector should be installed only in the master or leader of a parallel or three phase system.
Inverters: AC detector not needed.
4.3.3. Load the BMS VE.Bus assistant in all units (must be done for each unit separately)
4.3.4. Remove the MK2 and reconnect to the BMS.
4.3.5. The system is now ready for use
5. System examples
Figure 5: System with MultiPlus and DC loads
Note: the BMS is connected to the battery minus by the UTP cable between the BMS and the inverter/charger.
Therefore, in order to prevent ground loops, do not wire the BMS minus connector.
Figure 6: DC only system for a boat or vehicle with parallel connection of the starter- and Li-ion battery
Note: in this case the battery minus of the BMS must be wired.
