2.2 Safety Information

This section contains safety information that must be observed at all times when working on or with the product. 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 high voltages of the PV array

When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the DC conductors and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal electric shocks. If you unplug the terminal plate plate with the connected DC conductors from DC-in slot under load, an electric arc may occur, which can cause an electric shock and burns.

• Prior to performing any work on the inverter, always disconnect the inverter from voltage sources on the AC and DC sides as described in the inverter manual. When doing so, note that even if the DC load-break of the inverter is switched off, there will be dangerous direct voltage present in the DC conductors on the DC-in connecting terminal plate in the Connection Unit of the inverter.

Danger to life due to electric shock from touching an ungrounded product

Touching an ungrounded product can cause a lethal electric shock.

• Ensure that the product is integrated in the existing overvoltage protection.

Increased electromagnetic radiation through the antenna

During operation, the antenna produces an electromagnetic field and can interfere with other devices (e.g., pacemakers) due to electromagnetic interference.

• Persons must not remain closer than 20cm (8in) to the antenna for long periods of time.
