2 Safety
DANGER
Danger to life due to electric shock
when live components or DC
cables are touched
When exposed to light, the PV modules
generate high DC voltage which is present
in the DC cables. Touching live DC cables
results in death or lethal injuries due to
electric shock.
• Do not touch non-insulated parts or
cables.
• Disconnect the product from voltage
sources and ensure it cannot be
reconnected before working on the
device.
• Do not disconnect the DC connectors
under load.
• Wear suitable personal protective
equipment for all work on the product.
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 product from voltage
sources and ensure it cannot be
reconnected before working on the
device.
• Only touch the cables of the PV
modules on their insulation.
• 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.

DANGER
Danger to life due to electric shock
in case of overvoltages and if
surge protection is missing
Overvoltages (e. g. in the event of a flash of
lightning) can be further conducted into the
building and to other connected devices in
the same network via the network cables or
other data cables if there is no surge
protection. Touching live parts and cables
results in death or lethal injuries due to
electric shock.
• Ensure that all devices in the same
network are integrated in the existing
overvoltage protection.
• When laying the network cable
outdoors, ensure that there is suitable
surge protection at the network cable
transition from the product outdoors to
the network inside the building.
• The Ethernet interface of the product is
classified as "TNV-1" and offers
protection against overvoltages of up
to 1.5 kV.
