Wiring
Note
When the 24 V supply voltage is switched on at each channel, there is a "1" signal at the
module outputs for approx. 50 μs.
Tip: Using the potential jumpers
If you want to supply both load groups with the same potential (non-isolated), use the
potential jumpers supplied with the front connector. This helps you to avoid having to
terminate two wires to one terminal.
Proceed as follows:
1. Connect the 24 V DC supply voltage to terminals 19 and 20.
2. Insert the potential jumpers between terminals
– 9 and 29 (L+)
– 10 and 30 (M)
– 19 and 39 (L+)
– 20 and 40 (M)
3. Insert the jumpers between terminals 29 and 39, as well as 30 and 40.
4. Use the terminals 19 and 20 to distribute the potential to the next module.

Note
Ensure that the maximum current load of 8 A per potential jumper is not exceeded.
