aged, otherwise, it may cause danger!
• Before electrical connections, please make sure that the product switch and all
switches connected to the product are set to "OFF", and use measuring equip-
ment to ensure that there is no voltage at the connection. Otherwise, an electric
shock may occur!
• All switches cannot be closed until the electrical connection is completed.
PV modules will generate lethal high voltage when exposed to sunlight.
• Operators must wear proper personal protective equipment during electrical
connections.
• Before performing an electrical connection, be sure to disconnect the PVS and
use measuring equipment to ensure that cables are voltage-free.
• Respect the protection requirements and precautions of PV modules.
Danger to life due to a high voltage inside the inverter!
• Be sure to use special insulation tools during cable connections.
• Note and observe the warnings on the product.
• Respect all safety precautions listed in this manual and other pertinent
documents.
Sand and moisture penetration may damage the electrical equipment in the prod-
