7 Commissioning
Risk of injury due to incorrect installation!
We strongly recommend carrying out preliminary checks before
commissioning to avoid possible damage to the unit caused by faulty
installation.
7.1 Electrical checks
Carry out the main electrical checks as follows:
1.
Check PE connection: ensure the inverter has a reliable earth connection.
2.
Check the DC voltage values: check that the DC voltage of the strings does not
exceed the permitted limits.
3.
Check the polarity of the DC voltage: make sure the DC voltage has the correct
polarity.
4.
Check the PV string insulation to earth: make sure that the insulation resistance
to ground is greater than 1 MOhm.
5.
Check the grid voltage: check that the grid voltage at the point of connection of
the inverter within the permitted values.
Danger to life due to the presence of AC-Voltage!
• Only touch the insulation of the AC cables.
• Wear personal protective equipment such as insulating gloves.
Danger to life due to the presence DC-Voltage!
• Only touch the insulation of the PV array cables.
• Do not touch parts of the substructure and frame of PV array.
• Wear personal protective equipment such as insulating gloves.
