Ground/Chassis Ground Concept

Notice

Please note the instructions regarding the grounding and chassis ground concept in the SIMATIC S7 installation guides; see “SIMATIC S7 Programmable Controller S7−300 − Installation and Hardware: Installation Manual” /1/.

Behind the hinged panel on the left of the device, you will see a slider with which you can connect or disconnect the chassis ground of the 24 V power supply with reference ground.

SSlider pushed in: chassis and reference ground connected (note: the slider must be felt to lock in place).

SSlider pulled out: No connection between chassis and reference ground. When shipped: Slider pushed in

Use a screwdriver to set the slider.

Note

An Ethernet cable can also be inserted and removed with the power supply on.
