In the following cases, check the function that detects shorts across contacts prior to
commissioning:
– On evaluation devices with DC supply voltage: Overall cable resistance ≥ 15 Ohms
per channel
– On evaluation devices with AC supply voltage: Overall cable resistance ≥ 25 Ohms
per channel
– For details of how to perform the test for shorts across the contacts, please refer to
the operating manual for the relevant evaluation device.
