2.3 Safety Precautions
This section contains safety precautions 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 follow all safety precautions 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. 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 uninsulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned by qualified persons with the
appropriate skills only.
• 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 (see Section 10, page 54).
