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 disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock and burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by qualified persons with the
appropriate skills.
• If an error occurs, have it rectified by qualified persons only.
• Prior to performing any work on the inverter, disconnect it from all voltage sources as
described in this document.
Danger to life due to electric shock
Touching an ungrounded PV module or array frame can cause a lethal electric shock.
• Connect and ground the PV modules, array frame and electrically conductive surfaces so
that there is continuous conduction. Observe the applicable local regulations.
Damage to the inverter due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label and the LEDs
using only clean water and a cloth.

Allow the product to cool down sufficiently before carrying out any work.
Notice
This symbol indicates general dangers. In this case, it indicates that the in-
verter must be additionally grounded if local conditions require additional
grounding or equipotential bonding.
