  • Page 3: General Description

    Operating voltage range of the BMS: 9 to 70 V DC. Communicates with all VE.Bus products The VE.Bus BMS connects to a MultiPlus, Quattro or Phoenix inverter with a standard RJ45 UTP cable. Products without VE.Bus can be controlled as shown below: Load Disconnect The Load Disconnect output is normally high and becomes free floating in case of imminent cell under voltage.
  • Page 4 A Battery Protect will disconnect the load when: input voltage (= battery voltage) has decreased below a preset value, or when the remote on/off terminal is pulled low. The VE.Bus BMS can be used to control the remote on/off terminal (Non inverting remote on-off cable needed).

  • Page 5: Installation

    4. Installation 4.1 AC Detector for MultiPlus and Quattro The purpose of the AC Detector is to restart the MultiPlus or Quattro when AC supply becomes available, in case it has been switched off by the BMS due to low cell voltage (so that it can recharge the battery). Note 1: The AC Detector is not needed in case of an inverter.
  • Page 6 Connect the VE.Bus BMS to the AC Detector with a UTP cable (not included). If a VE.Bus control panel is used: connect to the Remote If a VE.Bus control panel is used: connect to the Remote Panel socket of the VE.Bus BMS. Figure 4: VE.Bus connections 4.2 Wire the system...

    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.
  • Page 8 Figure 7: System for a boat or vehicle with inverter/charger (DC fuses not shown) 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 8: System for a boat or vehicle with a three phase inverter/charger configuration (DC fuses not shown) Note 1: the AC Detector is installed only in the leader.
