CURRENT 8CH terminal
with an appropriate connector
Installation Instructions
High current flowing through potential jumpers U
jumpers and the internal temperature of the terminal to increase. Observe the following instructions
to keep the current flowing through the potential jumpers of the analog terminals as low as possible:
All of the analog terminals need a separate main circuit.
If this is not possible in your application and if you are using analog terminals in a main
circuit together with other terminals, place the analog terminals behind all the other
terminals at the end of the main circuit.
