Charge disconnect BMS to 1200w inverter charger connection question

Are they referring to the large positive battery connection post? Underlined below at the last sentence

Cable for Smart BMS CL 12-100 to MultiPlus (PN: ASS070200100)

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.

Hi @Out To Sea

Do not connect the cable to the battery connection posts!

Depending on the model the remote on/off input has either 2 (afaik the 1600VA) or 3 pins (500-1200VA). On a 3 pin terminal block the black wire connects to the ON terminal and the red wire connects to the + terminal of the remote on/off input of your MultiPlus. See also the connection overview in appendix A of the manual.

On a 2 pin connector (this has a wire loop installed by default), connect the black wire either to the left or right side of the terminal block and the red wire to the other side.
