Wiring harness components plug into the 5 connectors in the 2Q BMS:

  1. "RS485-0" Connector:  Normally connects to the REC WiFi unit with the cable supplied with the WiFi unit.  As part of this wire harness a spare connector is supplied with pins that an installer can use to connect to, e.g. an industrial RS485 interface in an industrial system.
  2. "RS 485 CAN T Cp" Connector with the following wires
    • "RS 485-1" no wires on these pins
    • "CAN" has a 0.5metre cable to a Weipu Series 13 connector  (note that mostly inverters and controllers use an RJ45 connector for their CAN Bus, however as there is no industry standard pin-out for the RJ45 this leg of the CAN Bus cable is a separate purchase)
    • "T" has a jumper wire
    • "Cp" no wires on these pins
  3. "CELLS" Connector with the following labelled wires with a clean cut at 2metres length (for termination by the installer):
