4.2.2. Review Safety Considerations

Operating power, including primary power source for operating the contactor coils, is provided to the
Low-Voltage BMS at two connectors:
1. positive at the Current Shunt / +V Power
2. negative at the Contactors / -V Power
The wiring of the battery cell voltage and temperature sensing should be verified
before connecting to the Low-Voltage BMS and Cell Interface. The temperature
sensing wires must be isolated from the cell voltage sensing leads. Although the

Low-Voltage BMS and Cell Interface include protective circuitry to make them 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 Low-
Voltage BMS, Cell Interface, and/or the cells.
