Take the following precautions for grounding the panel. Connect the functional ground (FG) terminal on the power plug to an exclusive ground.

|---|---|
|
1 |
Check that the grounding resistance is less than 0.1 Ω (1). |
|
2 |
The FG wire should have a cross sectional area greater than 2 mm (1). Create the connection point as close to the panel as possible, and make the wire as short as possible. When using a long grounding wire, replace the thin wire with a thicker wire, and place it in a duct. |
|
3 |
If the equipment does not function properly when grounded, disconnect the ground wire from the FG terminal. |
|
(1) Observe local codes and standards. Ensure the ground connection has a resistance of less than 0.1 Ω and that the ground wire has a cross-section of at least 2 mm2 or AWG 14. |

Take the following precautions for grounding the panel.
Electromagnetic Interference (EMI) can be created if the devices are improperly grounded. EMI can cause loss of communication.
Do not use common grounding, except for the authorized configuration described below.
If exclusive grounding is not possible, use a common connection point.
