Together with the shielding and earthing plate in the module holder, this constitutes the common, large-area ground for all I/O modules and for the external power supply.When a module is plugged into the module holder, a metal tab on the module housing creates a reliable multi-point contact to the module carrier concerned.The zero-potential (Minus pole) of the 24 V supply is connected to the Minus terminal of the supply. This should be connected to the earthing bar with the shortest possible wire (< 25 cm) of 1.5 mm2.
