2 IMPORTANT SAFETY INSTRUCTIONS
DANGER
Danger to life due to electric shock
when touching live system components
in case of a ground fault
If a ground fault occurs, parts of the system may
still be live. Touching live parts and cables results in
death or lethal injuries due to electric shock.
• Disconnect the inverter from voltage sources
and make sure it cannot be reconnected
before working on the device.
WARNING
Danger to life due to fire or explosion
In rare cases, an explosive gas mixture can be
generated inside the inverter under fault conditions.
In this state, switching operations can cause a fire
or explosion. Death or lethal injuries due to fire or
flying debris can result.
• In case of error, only carry out corrective
measures specified by SMA Solar
Technology AG (for corrective measures see
detailed manual of the inverter). If no
corrective measures are specified, do not
perform any actions on the inverter. Contact
the Service.
• Ensure that unauthorized persons have no
access to the inverter.
• Disconnect the AC circuit breaker and secure
it against reconnection.
• Disconnect the PV array from the inverter via
an external disconnection device. Do not
operate the DC load-break switch on the
inverter in the event of ground fault
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 1000 V or higher.
CAUTION
Risk of burns due to hot enclosure parts
The enclosure and the enclosure lid may get hot
during operation. The DC load-break switch can
not become hot.
• Do not touch hot surfaces.
• Wait until the inverter has cooled down
before touching the enclosure or enclosure
lid.

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). Observe
the applicable safety regulations.
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.
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.
