The wiring of the battery cell voltage and temperature sensing should be verified
before
connecting to the Cell Interface modules. The temperature sensing must be
isolated from the cell voltage sensing. Although the Cell Interface includes protective
circuitry to make it more resilient to brief wiring errors, the same circuitry can result
in the battery cells being slowly discharged. Over time, these wiring errors can cause
damage to the Cell Interface and/or the cells.
