6.2 Internal Electrical Connection of Energy Storage
6.2.1 Connecting Power Cord
Before connecting the energy storage battery module, ensure that the energy storage battery is not working
and the indicator lights on the battery are OFF. The power cord delivered with the product together should be
used to connect the positive and negative terminals of other batteries or power modules. It shall be noticed that
the red cable should be connected to the red terminal (positive battery terminal) and the black cable to the black
terminal (negative battery terminal).
Before electrical connection, please ensure that the switches of the energy storage are in the
"OFF" state. Otherwise, the high voltage of the device may cause electric shock.
The operations related to electrical connections must be carried out by professional electrical
technicians. When carrying out electrical connections, the operator must wear personal
protective articles.
