The two 230V sockets are active both when operating from the MAINS INPUT and when operating from the generator.
When operated from the MAINS INPUT, the two 230V sockets supply the same system (IT, TN, TT) as MAINS INPUT. The generator must be earthed in TT and TN systems with a copper cable 6-10 mm² (depending on local regulations) by connecting its earth screw to the same earth bar to which the MAINS 230V power source is earthed.
The two outlets after switching power to the generator supply only IT system without the grounded neutral conductor. Regulations and protective measures for the IT system must be observed.
With this version of the generator it is possible to supply electricity consumers that can work both in the TN and in the IT system. It is not possible to supply the house completely in automatic mode!
These instructions can only be taken as a recommendation, are illustrative and must be adapted to the exact local circumstances and conditions during installation.
The installation itself should be made by a licensed electrician and in accordance with all local standards and regulations. We take no responsibility for the wrong installations and their consequences.
