Protective ground
When the device is operated with multirange power supply unit 100 to 240 VAC / 60 to 250
VDC, the protective ground is connected in addition to the functional ground.
CAUTION
Danger from line voltage
Grounding simply via the housing is inadequate.
In this case, connect the functional ground to ensure reliable operation.
With devices with a supply voltage of 100 to 240 VAC / 60 to 250 VDC, you should also
connect the protective earth to the grounding bolt.
On the SCALANCE X-300EEC, the grounding bolt is on the bottom of the device.
On the SCALANCE XR-300M EEC, the grounding bolt is on the rear of the housing
between the power connectors.
To wire up the protective ground, use a copper cable of category 14-8 AWG or cable with a
cross-section of 1.5 to 6 mm².
Grounding bolts on the underside of the housing of the X-300EEC or on the rear of the XR-
300M-EEC
