Notice
Note dierences in potential
The load voltage supply and the signal voltage of the I/O module are electrically isolated.
• The connection of the load supply voltage and the signal voltage is only permissible when no compensating currents are
owing as a result of a dierence in potential.
• The connection of additional, external devices to terminals with the assignment 2M is not permissible. The additional load
may result in the destruction of the I/O module as well as further faults.
