All cables must be fed through a cable gland at a suitable position of the CAN bus module. Use suitable wire end ferrules for each wire that you place on a terminal.
Designation |
Function |
V+, GND |
Terminals for the supply voltage coming from the EasyNOₓ or from the first CAN bus module and for passing through the supply voltage to the NOX sensor and optionally to a second CAN bus module |
CAN-L, CAN-H |
Terminals for the CAN cable coming from the EasyNOₓ or from the first CAN bus module and for passing through the CAN signal to the NOX sensor and optionally to a second CAN bus module |
Note that each terminal is available twofold. If more than one wire has to be connected to a terminal, use suitable double wire end ferrules for a safe connection (not included in scope of supply).
Use these terminals to connect the CAN bus module to the supply voltage and the CAN cable from the EasyNOₓ or the first CAN bus module. Use a shielded CAN cable in compliance with the standards ISO 11898-2 and CiA® 303-1. Connect the shield of the CAN cable with the cable glands. Do not lay the shield inside the CAN bus module.
To pass through the supply voltage and the CAN signal, connect the NOX sensor and, if needed, a second CAN bus module to these terminals. The CAN cable to the second CAN bus module must be shielded and comply with the standards ISO 11898-2 and CiA® 303-1. Unless you use the CAN bus hybrid cable from MOTORTECH, the CAN and power supply cable to the second CAN bus module must be routed in parallel.
The connection cable from the CAN bus module to the evaluation unit of the NOX sensor is assigned as follows:
Color |
Assignment |
---|---|
White |
L + |
Brown |
L – |
Green |
CAN Lo |
Yellow |
CAN Hi |
Gray |
Node ID of the NOX sensor (see section Node ID NOₓ Sensor) |
To avoid coupling of interference signals, make sure that the CAN lines are not laid over the signal lines when wiring.
If you connect a second CAN bus module to the first CAN bus module, pass the power supply and CAN cable to the second CAN bus module through the large cable gland at the long side of the CAN bus module on the right.
