Unused wires can couple excessive system noise into Nuvation BMS which can disrupt communication and lead to undesirable behaviors.  Please be aware of high voltages present in your system and follow all necessary safety precautions.  The provided module enclosures are not fire enclosures.  Depending on battery chemistry, there might be a nominal voltage per cell which adds up in series and is always present. There are many different battery chemistries with different current capacities, and so high voltage with high current capacity may be present while connecting the Nuvation BMS. You must use proper electrical safety precautions when handling any part of the Nuvation BMS. Neither Nuvation Energy or any of its employees shall be liable for any direct, indirect, incidental, special, exemplary, personal or consequential harm or damages (including, but not limited to, procurement or substitute goods or services; loss of use, data, or profits; or business interruption) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this product.  The Nuvation BMS relies on your system charger to charge the battery cells; do not leave your charger off while the Nuvation BMS is powered from the stack for prolonged periods of time. The Nuvation BMS should be shut down when the system is in storage to minimize the drain on the cells. Installation Guide - 2018-10-08, Rev. 2.0 1
