CCU | User Manual 13 | 20 Figure 4 Wiring in iTraMS 5 General Info • Sensor signal wires should be separated from both actuator signals and ignition switching signals. • Correct fuse rating as per the system load to be calculated by the OEM and used on Battery positive supply. • Calculation for their ratings will be responsibility of the customer. • Twisted pair wires should be used for CAN signals (Figure 4). • For CCU power ground, multi-point grounding on chassis is recommended.
CCU | Operations Manual 7 19 | 20 Best Practice for Wiring Routing Due to the effects of gravity passing water through the wires, the CCU should be packaged higher than any wire end or splice in the harness. Measures should be taken to prevent water from collecting around the wiring harness. Plastic wire covering/protection should allow water to drain from harness. Wiring should be routed away from water drainage areas.
