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.
• Touch the cables of the PV array on the insulation
only.
• Do not touch any parts of the substructure or
frame of the PV array.
• Do not connect PV strings with ground faults to the
inverter.
Risk of injury due to toxic substances, gases
and dusts.
In rare cases, damages to electronic components
can result in the formation of toxic substances,
gases or dusts inside the inverter. Touching toxic
substances and inhaling toxic gases and dusts can
cause skin irritation, burns or poisoning, trouble
breathing and nausea.
• Only perform work on the inverter (e.g.
troubleshooting, repair work) when wearing
personal protective equipment for handling of
hazardous substances (e.g. safety gloves, eye
and face protection, respiratory protection).
• Ensure that unauthorized persons have no
access to the inverter.
Installation Guide
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
measurement ranges designed for the
maximum AC and DC voltage of the inverter.
Danger due to ground fault on DC side during
operation
Due to the transform erless topology of the product,
the occurrence of ground faults on DC side during
operation can lead to irreparable damage.
Damages to the product due to a faulty or
damaged DC installation are not covered by
warranty. The product is equipped with a protective
device that checks whether a ground fault is present
during the starting sequence. The product is not
protected during operation.
• Ensure that the DC installation is carried out
correctly and no ground fault occurs during
operation.
Risk of burns due to hot components
Some components (e.g. heat sink) inside the
inverter can become hot during operation.
Touching hot components can cause burns.
• The inverter is to be installed in such a way that
hot components cannot be touched.
• After opening the product, wait until the
components have cooled down.
• Wear suitable personal protective equipment
for all work on the product.
