Hello,
We have quite some lakeshore modules in our installation but when connecting the grounding pin to the cabinet ground bar the resistance increases from 0.1 to 0.5 Ohm. Can you please explain what can be the cause?
Thank you.

The Model 240 acquires its ground through the DIN Rail connection. The ground connection on the Input is for the shield of the cable and should not be connected to the cabinet grounding bar as that will create a ground loop.

Hi Jeff, we tried that at the beginning but without the shield pin connected to the cabinet grounding the signal was very noisy. Have you experienced that before?

The only time I have experienced this is if the rack is not grounded which means the DIN Rail is not grounded or the cable shield wire was grounded at both ends. Make sure that the Ground connector is present on the 240 which is a silver clip on the DIN Rail mounting location opposite of the spring loaded clip.

Thanks Jeff! Will talk with the team and come back if we have more questions, highly appreciated.

The increase in resistance when connecting the grounding pin to the cabinet ground bar might be due to various factors. It could be caused by loose connections, corrosion, or even the quality of the ground bar itself. I recommend checking and ensuring that all connections are secure and clean 3d result. If the issue persists, it might be a good idea to consult with a qualified electrician or technician to diagnose the specific cause and address it effectively. |
