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 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 48).
Danger to life due to electric shock
Touching an ungrounded PV module or array frame can cause a fatal 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 seal of the enclosure lids in subfreezing conditions
If you open the upper and lower enclosure lids in subfreezing conditions, the seals on the
enclosure lids can be damaged. This can lead to moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5°C.
• If a layer of ice has formed on the seal of the lid in subfreezing conditions, remove it prior to
opening the enclosure lids of the inverter (e.g. by melting the ice with warm air). Observe the
applicable safety regulations.
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.
