Tip: Using the potential jumpers
Use the potential jumpers supplied with the front connector if you want to connect the four
load groups to the same potential (non-isolated). 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 the following 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 9 and 10 to loop the potential to the next module.

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