Safety Instructions:

1. Installation by Professionals: The installation should only be carried out by qualified and authorized professionals.
2. Wear Protective Equipment: When handling PV modules, use appropriate protective equipment such as gloves and safety glasses.
3. Components must operate within the technical specifications listed in their data sheets.
4. Use only manufacturer-approved accessories.
5. Do not install components if they are physically damaged or equipped with damaged or substandard cables or connectors.
6. No Work Under Voltage: Perform installation or maintenance work only when the system is de-energized.
7. Do not apply an external voltage source to a module or a string with components.
8. Protection from External Influences: Install protective conduits and cables in a way that shields them from UV radiation, rodents, and mechanical damage.
9. Protection from Moisture and Dirt: Store and install accessories in dry and clean locations to prevent damage from moisture or contamination.
10. Regular Inspection: Inspections and maintenance should be carried out regularly to detect potential damage or signs of aging at an early stage.
