sensor module must be connected to the earth of the system.
7.2.3
Wiring of Thermocouples
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.
Connect the first thermocouple to input 1. Optionally, connect the second thermocouple to input
2 (see section
Installation Locations of Thermocouples
on page 55). Depending on the layout,
connect the thermocouples as follows:

er
Second exhaust gas
line: after catalytic
converter
If you do not use input 2, bridge this input with a jumper between the ter and –. This
prevents the measuring circuit from being disturbed by interfering radiation.
Only use thermocouples with shielded leads. When connecting, make sure that the terminal
designation corresponds to the polarity of the thermocouples.
Connect the thermocouples as follows:
Connect the shields of the thermocouple leads with the cable glands. Do not lay the shields in-
side the CAN bus module.
