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 cables of the inverter are touched
High voltages are present in the conductive components or cables of the inverter. Touching live parts and cables of
the inverter results in death or lethal injuries due to electric shock.
• Disconnect the inverter from voltage sources and make sure it cannot be reconnected before working on the
device.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch non-insulated parts or cables.
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 inverter from voltage sources and make sure it cannot be reconnected before working on the
device.
• Only touch the cables of the PV modules on their insulation.
• 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 5 minutes before touching any parts of the PV system or the product.
Danger to life due to fire or explosion
In rare cases, an explosive gas mixture can be generated inside the inverter under fault conditions. In this state,
switching operations can cause a fire inside the inverter or explosion. Death or lethal injuries due to hot or flying
debris can result.
• In the event of a fault, do not perform any direct actions on the inverter.
• Ensure that unauthorized persons have no access to the inverter.
• Disconnect the PV array from the inverter via an external disconnection device. If there is no disconnecting
device present, wait until no more DC power is applied to the inverter.
• Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped, and secure it against
reconnection.
• Only perform work on the inverter (e.g., troubleshooting, repair work) when wearing personal protective
equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory
protection).
