2.2 Safety Precautions
DANGER!
Danger to life due to high voltages in the inverter.
• All work on the inverter and the connection of the SMA Plug-in Grounding may be
carried out only by a qualified electrician.
DANGER!
Electric shock caused by high voltage in the inverter!
• Disconnect the inverter from both the AC and DC sides before you connect the
SMA Plug-in Grounding, as described in the inverter's installation guide.
NOTICE!
A faulty connection may damage the SMA Plug-in Grounding or the inverter!
A faulty connection of the SMA Plug-in Grounding set can lead to short circuits and can
cause irreparable damage to the SMA Plug-in Grounding and the inverter. All warranty
claims become void.
• Connect the SMA Plug-in Grounding as described in the following sections.
Connection of conductive parts in the substructure of the PV generator with the
grounding system
Certain module manufacturers demand the grounding of a generator terminal in order to
avoid potential differences between the ground potential of the grounding set and the
surrounding of the PV generator. By grounding the substructure of the PV generator these
differences in potential will be avoided. Additionally this potential equalization provides
the best possible protection via the fuse integrated in the grounding set.
