The length of the optical fiber between the HC8X or an I/O module box and the measuring
system PC may not exceed 60 m.

Installing the HC8X
Control unit damage by overheating!
Install the HC8X horizontally, if possible.
If required, install the HC8X vertically so that the ventilator on the side points downward
Ensure adequate heat dissipation.
Install the HC8X so that the internal control unit ventilator can draw in cool air unhin-
dered.
