NOTICE
Damage to the enclosure seal in subfreezing conditions
If you open the inverter when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the inverter if the ambient temperature is not below -5°C.
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the inverter (e.g. by melting the ice with warm air).
NOTICE
Damage to the product due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
• Only open the inverter if the humidity is within the thresholds and the environment is free of
sand and dust.
• Do not open the inverter during a dust storm or precipitation.
• Close tightly all enclosure openings.
NOTICE
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.
Grounding conductor test prior to recommissioning
Prior to recommissioning SMA inverters after the installation of SMA components or power
assemblies which cannot be replaced intuitively, ensure that the grounding conductor in the
inverter is correctly connected. The function of the grounding conductor must be ensured and
all locally applicable laws, standards and directives must be observed.
Observe superordinate standards
The repair work on devices and the consideration and application of other standards which
correspond to a superordinate standard is the responsibility of the qualified person performing
the work. Unauthorized alterations will void guarantee and warranty claims and in most cases
terminate the operating license. SMA Solar Technology AG shall not be held liable for any
damage caused by such changes.
