Protective Connection of a point in the device, system or installation to earth to protect
earthing (PE) against electric shock in the event of a fault. When installing the Tauro inverter,
the PE connection is mandatory as it is a protection class 1 device. When con-
necting the PE conductor, ensure that it is secured against accidental disconnec-
tion. All points listed under "Connecting the inverter to the public grid (AC side)"
must be observed, including the use of washers, screw locks, and nuts with the
defined torque.
It must be ensured that when using the strain-relief devices, the ground con-
ductor is the last to be disconnected in the event of a possible failure. When con-
necting the ground conductor, the minimum cross-section requirements spe-
cified by the respective national regulations must be observed. In addition, the
minimum cross-section of the PE conductor must be at least half of the phase
cross-sections according to the product standard IEC 62109-1, as a cross-sec-
tion of at least 35 mm² (50 kW) or 70 mm² (99.99 / 100 kW) must be used for the
phases (L1 / L2 / L3).
