Installation Guide
5.1.3 PE connection between AC cabinet and DC / inverter cabinet
The PE rails for the individual switch cabinets are located at the bottom of the side areas. The two PE
rails with the prefabricated PE bridge which is already connected in a switch cabinet must be
connected together when putting together both inverters.
Example PE connection between the switch cabinets of the Sunny Central 500HE
Checking the grounding connection
When connecting the grounding connection, make sure that the screws are securely
positioned.
Position of the PE rail
Depending on the construction, the exact position of the PE rail in some switch cabinets is
located behind the fuse strip in the DC cabinet or behind the transformer in the AC cabinet.
With the help of the equipment identifier and the provided circuit diagram, the exact
position of the PE rail can be determined.
