Connecting the PV Generator

￿!

· Preparation

Please note that the NT 10000 has three independent DC inlets. The PV generators may have different ratings, but they must be compatible with the specifications of the Solar Inverter.

1.Install the DC cables in accordance with the system ratings prescribed by your PV planner. Measure the no-load voltage and the short-circuit current of each PV phase to make sure they work perfectly.

2.Read the type plate of the Solar Inverter to make sure it is licensed for the maxi- mum PV generator voltage.

3.To avoid dangerous touch voltage during the assembly of PV systems, the positive and negative conductors must be kept away from the earth potential (PE) electrically.

4.Accessible and conductive parts of the PV generator (e. g. metal frame, support structure, etc.) must be earthed (connec- tion to PE).

5.Make sure the PV generator is earth- fault free.

6.Connect the Solar Inverter to the power line.
