2.3 Symbol on the Product
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.
• All work on the inverter must be carried out by qualified persons only.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage
sources (see inverter manual).
• Do not touch any live components of the inverter.
Risk of burns due to hot inverter enclosure parts
Some parts of the inverter 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 inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through electrostatic
discharge.
• Ground yourself before touching any component.
