Victron energy VE.Bus BMS Manuel page 6

Installation procedure (see figure 3)
1. Connect the red AC1 wires to the neutral and phase of the AC-in-1 input.
2. Quattro: connect the black AC2 wires to the neutral and phase of the AC-in-2 input.
MultiPlus: no AC-in-2 input available. Please cut the AC2 wires close to the AC Detector
Figure 3: Connecting the AC Detector
3. Use the short RJ45 UTP cable to connect the AC Detector to one of the two the VE.Bus sockets in the MultiPlus or
Quattro (see figure 4).
4. Connect the VE.Bus BMS to the AC Detector with a UTP cable (not included).
5. Any control panel, such as the Color Control or the Digital Multi Control panel must be connected to the VE.Bus BMS.
Do not connect a control panel directly to a Multi or Quattro
signals from the VE.Bus BMS).

4.2 Wire the system: see system examples below
Do not connect to the battery plus at this stage (alternatively: do not insert the battery fuse(s)).
Important:
1. The UTP cable to the inverter or inverter/charger also connects the battery minus to the BMS.
In this case, in order to prevent ground loops, do not wire the battery minus connector of the BMS.
2. Wire the positive supply input of the VE.Bus BMS to the system positive. A system on-off switch in the positive supply
wire will disable the system when opened.
