Do not install alternator on a vehicle

Hello together, I need some help. And I want to connect an alternator to a system that consists of a battery and a few consumers. The alternator is constantly driven, while consumers do not always need juice. Now the question is how to wire it properly without risking overload or overvoltage? Rich plus and minus out, because the Lima itself regulates this or do I need one of the three pins on the additional plug somewhere This is the alternator :https://www.ebay.de/itm/385346156498?… The system works with 24v and two new 12v batteries are switched in series. In the appendix you can also see the data sheet of the Lima.
