2 Safety
SMA Solar Technology AG
Operating manual 11HM-20-BE-en-19
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As with all electrical
or electronical devices, there are residual risks despite careful construction. To prevent personal injury and property
damage and to ensure long-term operation of the product, read this section carefully and observe all safety
information at all times.
DANGER
Danger to life due to electric shock when live components or cables are touched
High voltages are present in the conductive components or cables of the product. Touching live parts and cables
results in death or lethal injuries due to electric shock.
• Disconnect the product from voltage sources and make sure it cannot be reconnected before carrying out any
work on the product.
• Before carrying out any work on the product, disconnect the grid side from all voltage sources using the
installed disconnect switch.
• Ensure that the conductors to be connected are de-energized.
• Clean the product with a dry cloth only.
• Only use the product in a dry environment and keep it away from moisture.
• Install the product in the switch cabinet only and ensure that the connection areas for the line conductors and
the neutral conductor are behind a cover or have contact protection.
• Observe the prescribed minimum clearance between the network cable and live installation components, or
use suitable insulation.
DANGER
Danger to life due to electric shock if external disconnect switch is missing
High voltages are present in the conductive components. Touching live parts results in death or lethal injuries due to
electric shock.
• Install an external disconnect switch between the product and the grid-connection point. The external
disconnector must be close to the product and easily accessible.
• Before carrying out any work on the product, disconnect the grid side from all voltage sources using the
installed disconnect switch.
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.
WARNING
Danger of fire due to missing or incorrect fuse
If a fuse is missing or incorrect and a fault occurs, a fire may be caused. This can result in death or serious injury.
• Protect the line conductors of the product with a fuse or a selective circuit breaker with max. 63A.
