9.1.9 Shielding within the Input and Output Areas
Lay field cables for sensors and actuators separately from the power supply lines and at a
sufficient distance from electromagnetically active devices (electric motors, transformers).
To avoid interferences, ensure that the field cables are provided with continuous shielding. To
this end, connect the shielding on both ends of the field cables. This applies, in particular, to
field cables of analog inputs and proximity switches. Exception: The shield in the F 6217 may
only be connected to the rack.
If high compensation currents are expected, the shielding must be applied on at least one end.
Further measures, e.g., galvanic separation, must be implemented to avoid compensation
currents. Additionally, the requirements specified in the module-specific manuals must be
observed.
9.1.10 Lightning Protection for Data Lines in HIMA Communication Systems
Lightning protection for data lines can be improved by implementing the following measures:
Completely shield the field wiring of the HIMA communication systems.
Properly ground the system.
Install lightning protection devices in places outside of buildings and exposed to lightning.
9.1.11 Cable Colors
The cable colors used in the HIQuad X systems comply with international standards.
Notwithstanding the HIMA standard, other cable colors can be used for wiring due to national
standard requirements. In such a case, document and verify the deviations.
9.1.12 Connecting the Supply Voltage
Connect the supply voltage infeed lines to the clamp terminal blocks of the base racks (L1+,
L2+, L1-, L2-).
Attach the supply voltage infeed lines of the system fan to the screw terminals.
