2.2 Important safety information
Danger to life due to electric shock when live components or
cables are touched
• All work on the inverter must only be carried out by qualified
personnel who have read and fully understood all safety
information contained in this manual.
• Do not open the inverter.
• Children must be supervised to ensure that they do not play
with the inverter.
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 9 "Disconnecting the Inverter from Voltage Sources").

2.3 Symbols on the label
Symbol
Explanation
Beware of a danger zone
This symbol indicates that the inverter must be additionally
grounded if additional grounding or equipotential bonding is
required at the installation site.
Risk of injury 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.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• During operation, do not touch any parts other than the
enclosure lid of the inverter.
Damage to the inverter due to electrostatic discharge
Internal components of the inverter can be irreparably
damaged by electrostatic discharge.
• Ground yourself before touching any component.

10 User Manual UM0014_ASW 3K-20K-LT-G2 PRO_EN_V02_0622
Beware of high voltage and operating current
The inverter operates at high voltage and current. Work on the
inverter must only be carried out by skilled and authorized
electricians.
Beware of hot surfaces
The inverter can get hot during operation. Avoid contact during
operation.
WEEE designation
Do not dispose of the inverter together with the household
waste but in accordance with the disposal regulations for
electronic waste applicable at the installation site.
CE marking
The product complies with the requirements of the applicable
EU directives.
Certification mark
The product has been tested by TUV and got the quality
certification mark.
RCM Mark
The product complies with the requirements of the applicable
Australian standards.
Capacitors discharge
Before opening the covers, the inverter must be disconnected
from the grid and PV array. Wait at least 5 minutes to allow the
energy storage capacitors to fully discharge.
Observe the documentation
Observe all documentation supplied with the product
