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 (see Section10 "Disconnecting the Inverter from Voltage

Sources", page45).

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.

Risk of burns due to hot enclosure parts

Some parts of the enclosure can get hot during operation.

• Do not touch any parts other than the lower enclosure lid of the inverter during operation.

Damage to the display or the type label due to the use of cleaning agents

• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label, the display and

the LEDs with a damp cloth only.
