Victron Cable for Smart BMS CL 12-100 to MultiPlus

This cable connects between a non VE.Bus BMS (Smart BMS CL 12-100 or smallBMS) and a MultiPlus (MultiPlus, MultiPlus Compact or MultiPlus-II).

This cable will allow the MultiPlus 500VA -1600VA, MultiPlus Compact 800VA - 2kVA and MultiPlus-II models to be used with BMS products that have no VE.Bus interface, such as the Smart BMS CL 12-100 and the smallBMS. These MultiPlus models can be controlled from the Load/Charge Disconnect outputs and Load/Charger outputs respectively.

The cable will turn the MultiPlus off as soon as the BMS has detected a low voltage, high voltage or temperature alarm condition in the Victron lithium-iron-phosphate (LiFePO4) Smart Battery bank. Once the alarm condition has been cleared, the BMS will turn the MultiPlus back on.

The cable must be wired to the remote on/off connector of the MultiPlus models:

• When used with the MultiPlus 500VA-1200VA models connect the black wire to the ON terminal and the red wire to the (+) terminal.
• When used with the MultiPlus Compact 800VA-2kVA models connect the black wire to the middle terminal and the red wire to the right (IN) terminal.
• When used with the MultiPlus-II models connect the black wire to the lower (-) terminal and the red wire to the upper (+) remote on-off terminal.

Both the Load/Charge Disconnect outputs of Smart BMS CL 12-100 and Load/Charger outputs of the smallBMS must be in ‘High’ state in order for the MultiPlus to operate. After shutdown due to low battery voltage, run the alternator or use a battery charger on the primary side of the BMS to reset the system. The MultiPlus will then switch on and start charging (if connected to an AC power source).
