WARNING
Danger to life due to electric shock from destruction of the measuring device
due to overvoltage
Overvoltage can damage a measuring device and result in voltage being present in the
enclosure of the measuring device. Touching the live enclosure of the measuring device results in
death or lethal injuries due to electric shock.
• Only use measuring devices with a DC input voltage range of 800 V or higher.
CAUTION
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation. Touching hot enclosure parts can
result in burn injuries.
• During operation, do not touch any parts other than the enclosure lid of the inverter.
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 inverter due to sand, dust and moisture
Sand, dust and moisture penetration can damage the inverter, thus impairing 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 the inverter in case of interruption of work or after finishing work.
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.
