IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As
with all electrical or electronical devices, there are residual risks despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
Danger to life due to electric shock when live components or DC conductors
are touched
When exposed to sunlight, the PV modules generate high DC voltage which is present in the DC
conductors. Touching live DC conductors results in death or lethal injuries due to electric shock.
• Disconnect the product from voltage sources and make sure it cannot be reconnected
before working on the device.
• Do not touch non-insulated parts or cables.
• Do not remove the terminal block with the connected DC conductors from the slot under
load.
• Wear suitable personal protective equipment for all work on the product.
Danger to life due to electric shock when touching live system components in
case of a ground fault
If a ground fault occurs, parts of the system may still be live. Touching live parts and cables
results in death or lethal injuries due to electric shock.
• Disconnect the product from voltage sources and make sure it cannot be reconnected
before working on the device.
• Touch the cables of the PV array on the insulation only.
• Do not touch any parts of the substructure or frame of the PV array.
• Do not connect PV strings with ground faults to the inverter.
• Ensure that no voltage is present and wait five minutes before touching any parts of the PV
system or the product.
