Earth Grounding of EN60204-1 Applicable
Systems
If system protective earth grounding is planned, use a
►
cable as short as possible for grounding:
min. 1.5 mm² (16 AWG).
For connection details, refer to the following examples.
►
Example 1
Connecting and earthing the EAGLE and its Panel Bus I/O
Modules together with other controllers (e.g., the LION) and
their I/O modules powered by a single transformer and
earth-grounded as per EN60204-1.
Connect earth ground to terminal 1 of the EAGLE
►
Controller. Connect earth ground to terminal 74 of its
corresponding Panel Bus I/O Module.

Example 2
Connecting and earthing the EAGLE together with other,
mixed controllers earth-grounded as per EN60204-1.
NOTE: Use a noise-free earth ground inside the cabinet.
NOTE: Use one star-point to split power for controllers and
field devices.
NOTE: If the transformer is used for several controllers,
each controller ground has to be wired separately
to the star-point.
NOTE: If a field device that prohibits earth grounding is
connected to the system ground, an isolation
monitoring device must be used instead of earth
grounding.
NOTE: If the field device transformer is physically far away
from the controller, earth grounding must still be
performed for the controller.
Connect earth ground to the respective terminal of the
►
controllers, see Fig. 36.
