Safetyduring Electrical Connection

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 theDC conductors and the live components of the inverter.

Touching the DC conductors or the livecomponents can lead tolethal electric

shocks. If you disconnect the DC connectors from theinverter 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

qualifiedpersons with the appropriate skills.

• If an error occurs, have it rectified by qualified persons only.
• Before assembling the DC connectors, please first cover the PV modules with

apaque material.

• Prior to performing any work on the inverter, disconnect it from all

voltagesources as described in Section 8.
