5 Installation Instructions
High current flowing through potential jumpers U
M
and U
S
leads to a temperature rise in the potential jumpers and inside
the terminal. Observe the following instructions to keep the current flowing through the potential jumpers of the analog
terminals as low as possible:

Create a separate main circuit for each analog terminal.
If this is not possible in your application and you are using analog terminals in a main circuit together with other
terminals, place the analog terminals after all the other terminals at the end of the main circuit.
