Connecting the ground conductor

A connected ground conductor conducts potentially hazardous electrical charges to the metal
enclosure. The current flowing through the ground conductor in such a case trips the line-
side fusing device that disconnects the device from the power supply.
Moreover, the ground conductor improves the conduction of interference that is transmitted
via external power supply cables, signal cables, or cables to peripheral devices. The
connection for the ground conductor is marked with the following symbol:
Minor injury and danger of fire
In the interior of a nonconforming device, a dangerous voltage may be present that causes
a fire or an electric shock if touched.
• Connect the ground conductor first, before starting up the device.
• The ground conductor for the device must be connected to the ground conductor for the
• Never operate the device without a ground conductor.
• Remove the nonconforming device from use immediately and label it as nonconforming.
