Option 2: Direct voltage supply with 24 V DC
If no master is available, you can operate the overload relay with a 24 V DC voltage source in
conjunction with the operator panel.
For this purpose, connect the overload relay with the voltage source via the two cables L+ and
L-. Since the cable C / Q is not used in this case, communication via the IO-Link is not possible.
You cannot adjust the parameters "Cold start", "Ground fault detection", "Operator panel
available" and "Operation at Preset <> Actual Configuration".
