Hi, perhaps someone can help.
We have to recertificate a device. From EN62061 we changed to EN61326-3-1.
In EN61326-3-1 in table 6 (german version) they discribe, that signal
lines, which connected to power supply have to test with 2kV symmetric
an 4kV asymmetric and such lines have to test with a
coupling/decoupling network for supply lines (2 Ohm or 12 Ohm)
We have a DC24V device. I don't understand why we must test the signal
lines with the twice of voltage of the power lines. Die signal lines
are connected to the same DC24V source like the power lines.
The device will be build in a cabinet (IP20) as part of a machine.
It's a safety-relevant device.
Is this a faulty part of the standard?
We will destroy about 18 devices, because we have to repeat every test
three times (criterion DS).
Thanks and have a nice day, Thomas
