Protective earth-
ing (PE)
Connection of a point in the device, system or installation to earth to protect against elec-
tric shock in the event of a fault. When installing a safety class 1 inverter (see Technical
data), the ground conductor connection is required.
When connecting the ground conductor, ensure that it is secured against accidental dis-
connection. All the points listed in the chapter Connecting the inverter to the public
grid (AC side) on page 58 must be observed. It must be ensured that when using the
strain relief devices, the ground conductor is the last to be disconnected in the event of a
possible failure. When connecting the ground conductor, the minimum cross-section
requirements specified by the respective national standards and guidelines must be
observed.
