diameter of 8.3 mm. The electrical cables between the sensors and the control units
must not be spliced. The NO

sensors and control units must not be painted.
If the ambient temperature at the NO
x
sensor control units is too high, the control
units may be damaged.
Maximum permitted ambient temperature at the NO
x
sensor control units is 90 C.
Measure the ambient temperature when installation is complete. Refer to 01:08
