EAGLE CONTROLLER – INSTALLATION & COMMISSIONING INSTRUCTIONS
27 EN1Z-0970GE51 R1112
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.
