Page 10 (32)4.3.7 CAN1 and CAN2 (⑥, green ●)The CANopen connections (type: RJ45/8P8C) are usedas input and output per battery pack in order to seriesconnect the battery string for communicating with theIMU as described in the section 4.4 Signals IMU.CANopen is a series bus which must have a terminationof 120Ω at each end. The termination can vary in designand connection type on the ingoing side. As an endtermination on the battery pack side it shouldpreferably consist of an RJ45 connection type.The IMU will be reset if a voltage of 4-28VDC (related to0V Pin #4 or Pin #8) is applied to pin #5 in the CANconnection.Termination, battery pack side: RJ45, 120Ω (e.g. CPOINTXLRJ45-DMXTERM-120)Connector: Shielded RJ45Figure 18: CAN1 and CAN2 connection, schematicFigure 19: Design, CANopen connector, Shielded RJ45Figure 20: Design, CANopen termination 120Ω RJ45, type CPOINT XLRJ45-DMXTERM-1204.3.8 Fan (⑦, yellow ●)This connection can power an external fan for coolingeach battery pack.Connector: Molex 51103-0400 (or corresponding)Nominal voltage: 12VDC to 24VDC (depending onsystem setup)Max fan power: 12WFigure 21: Fan connection, schematic
