Please note the following here:
For earthed solar generators: Only use option 2 (with the galvanically

isolated low-voltage coils).
 For questions regarding transformer design: Contact the manufacturer
If you are using a transformer without isolated low-voltage coils, you can
connect a maximum of four central inverters.
Please note the following here:
 The transformer must be suitable for use on the central inverter.
If you earth the solar generator, each central inverter must have a separate
medium-voltage transformer or a separate low-voltage coil.

Procedure
1. Remove the lower protective cover
2. Check the cable lead of the AC cable
Material damage due to unsuitable cable lugs
The cable lugs used must match the selected cable diameter, the device's
connection bar and the diameter of the threaded bolt. If unsuitable cable
lugs are used, they may work loose, thereby interrupting the flow of
current and causing material damage.
 Use cable lugs of the correct size
 Only crimp the cable lugs with approved tools
 Do not use aluminium cable lugs
 If aluminium cables are used, use aluminium-copper washers or
aluminium-copper transition cable lugs.
3. Crimp the cable lugs.
Material damage due to loose screw connections
If the specified tightening torques are not observed, the screws may work
themselves loose as a consequence of magnetic influences or vibration in
the connection bars. Loosened screw connections change the resistance
and the conductivity at the connection. This can adversely affect operation
of the product, which may in turn suffer damage.
 Check connections before commissioning the device
Leave screws and nuts untreated. Do not treat with grease or otherwise
