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. You will find a
detailed operating 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 upper enclosure lid.
• Disconnect the inverter from all voltage sources before working on the inverter or the PV array:
