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.
• 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 is switched off, there will be dangerous direct voltage
present in the DC conductors 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.
Damage to the inverter or product due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter or the product
through electrostatic discharge.
• Ground yourself before touching any component.
