Wiring harness components plug into the 5 connectors in the 2Q BMS:
"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.
"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
"CELLS" Connector with the following labelled wires with a clean cut at 2metres length (for termination by the installer):
17 cell wires labelled as follows: "Cell 1-", "Cell 1+", etc to "Cell 16+"
Power supply wires labelled: "Pack -", "Pack +"
Pre-charge wire labelled: "Precharge"
"Isens Tsens" Connector with the following labelled cables each 2metres length
DS18B20 digital temperature sensor x 2 (unlabelled)
Shunt sense cable with 4mm lugs with 1 labelled "+" that attaches to the battery side of the shunt
"Power symbol I/Os" Connector with 1 metre length cable and wire as follows:
