WARNING
Danger to life due to electric shock
Under fault conditions, when working on the power supply circuit there may be dangerous
voltages present on the product. This can result in death or serious injury.
• For power supply units with a fixed connection, make sure that a disconnection unit (e.g.
miniature circuit breaker) is present outside the power supply unit.
• For power supply units with a plug connection, make sure that the electrical outlet for the
power supply unit is close to the power supply unit.
• The disconnection unit and the electrical outlet for the power supply unit must be freely
accessible at all times.
CAUTION
Damage due to electromagnetic radiation
This product
• Persons must not remain closer than 20 cm (8 in) to the product for long periods of time.
NOTICE
Damage to the product due to condensation
If the product is moved from a cold environment to a warm environment, condensation may form
in the product. This can damage the product or impair its functionality.
• When there are large temperature differences, wait until the product has reached room
temperature to connect the voltage supply.
• Make sure the product is dry.
NOTICE
Manipulation of PV system data in Ethernet networks
You can connect the supported SMA products to the Internet. When connected to the Internet,
there is a risk that unauthorized users can access and manipulate the data of your PV system.
• Set up a firewall.
• Close unnecessary network ports.
• If absolutely necessary, only enable remote access via a virtual private network (VPN).
• Do not use the port forwarding feature. This also applies to the used Modbus ports.
• Disconnect system components from other network components (network segmentation).
