3 Safety Information
Danger to life due to electric shock
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 disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock and burns. This manual is
intended only for electrically qualified persons trained in the installation and commissioning of
electrical devices and installations and experienced in mounting and commissioning PV systems.
In addition, you can find a detailed installation manual at www.SMA-Solar.com
• Work on the inverter must only be performed by electrically qualified persons.
• Do not touch the DC conductors or any other uninsulated conductors.
• Do not open the enclosure lid.
• Before performing any work on the inverter or PV array, always disconnect the inverter from
voltage sources in the following sequence. Only after the final step has been completed, is
there no voltage present in the inverter.
