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 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). Visit our pages for car battery and Yuasa battery
