The grounding resistance between the S-Panel PC ground wire and the ground must be 100 Ω or less. When using a long grounding wire, check the resistance and, if required, replace the wire with a thicker wire and place it in a duct.
The table shows the maximum length for the wires:
|
Wire cross-section |
Maximum line length |
|---|---|
|
2.5 mm2 (AWG 14) |
30 m (98 ft) |
|
60 m (196 ft) round trip |

UNINTENDED EQUIPMENT OPERATION |
|
oUse only the authorized grounding configurations shown below. oConfirm that the grounding resistance is 100 Ω or less. oTest the quality of your ground connection before applying power to the device. Excess noise on the ground line can disrupt operations of the Magelis Industrial PC. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
The S-Panel PC ground has 2 connections:
oDC Supply voltage
oGround connection pin
1 Supply voltage
2 Ground connection pin (functional ground connection pin)
3 Switching cabinet
4 Grounding strip
NOTE: For AC use the AC power supply module.

Step |
Action |
|---|---|
|
1 |
Ensure all of the following is done for the system wiring: oConnect the cabinet to ground. oEnsure that all cabinets are grounded together. oConnect the ground of the power supply to the cabinet. oConnect the ground pin of the S-Panel PC to the cabinet. oConnect the I/O to the controller if needed. oConnect the power supply to the S-Panel PC. |
|
2 |
Check that the grounding resistance is 100 Ω or less. |
|
3 |
When connecting the SG line to another device, ensure that the design of the system/connection does not produce a ground loop. NOTE: The SG and ground connection screw are connected internally in the S-Panel PC. |
|
4 |
Use 2.5 mm2 (AWG 14) wire to make the ground connection. Create the connection point as close to the S-Panel PC as possible and make the wire as short as possible. |

|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
oIf wiring of I/O lines near power lines or radio equipment is unavoidable, use shielded cables and ground one end of the shield to the Magelis Industrial PC ground connection screw. oDo not wire I/O lines in proximity to power cables, radio devices, or other equipment that may cause electromagnetic interference. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
