7.2.5 Wiring of Power Supply and CAN Bus
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
EasyNO
ₓ
or from the first CAN bus module and for
passing through the supply voltage to the NO
X
sensor
and optionally to a second CAN bus module
CAN-L, CAN-H Terminals for the CAN cable coming from the EasyNO
ₓ
or from the first CAN bus module and for passing
through the CAN signal to the NO
X
sensor and optional-
ly to a second CAN bus module
Note that each terminal is available twofold. If more than one wire has to be connected to a ter-
minal, use suitable double wire end ferrules for a safe connection (not included in scope of sup-
ply).
Use these terminals to connect the CAN bus module to the supply voltage and the CAN cable
from the EasyNO
ₓ
or the first CAN bus module. Use a shielded CAN cable. 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 NO
X
sensor and, if needed, a
second CAN bus module to these terminals. The CAN cable to the second CAN bus module must
be shielded. 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 NO
X
sensor is as-
signed as follows:
