Connecting the Earth Terminals of Several Control Cabinets
Central earth should possibly be free of interference voltage. If this cannot be ensured,
provide the controller with its own earthing.

Connections
Shielding within the Input and Output Areas
Lay field cables for sensors and actuators separately from the power supply lines and
sufficiently distant from electromagnetic active devices (electric motors, transformers).
Ensure that the cables to the input modules of the HIMax systems are laid as interference-
free as possible, e.g., as shielded cables. This particularly applies to cables with analog
signals and proximity switches.
For more information on shielding and earthing requirements, refer to the module manuals.
Lightning Protection for Data Lines in HIMA Communication Systems
To minimize problems due to lightning:
Completely shield the field wiring of the HIMA communication systems
Properly earth the system
Install lightning protection devices in places outside of buildings and exposed to lightning.
Cable Colors
The cable colors used in the HIMax devices comply with international standards.
