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.
• With permanently connected power supply
units, ensure that there is a disconnection unit
(e.g. circuit breaker) present outside of the
power supply unit.
• With pluggable power supply units, ensure
that the outlet for the power supply unit is
close to the power supply unit.
• The disconnect unit and the outlet for the
power supply unit must be freely accessible at
all times.
WARNING
Danger of fire due to incorrect
installation
• Have the product mounted, installed and
commissioned only by qualified persons with
the appropriate skills.
• Never open the product.
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 moisture
The product is not splash-proof. Moisture can
penetrate the product and damage it.
• Only use the product in a dry, indoor
environment.
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.
• When there is a large temperature difference,
wait for the product to reach room
temperature before connecting to 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).
NOTICE
High costs due to inappropriate Internet
tariff
Depending on use, the data volume of the product
transferred via the Internet may vary in size. The
data volume depends, for example, on the number
of inverters in the system, the frequency of device
updates, the frequency of data transfer to
Sunny Portal or the use of FTP push. High costs for
the Internet connection can be the result.
• SMA Solar Technology AG recommends
using an Internet flat rate with a monthly data
volume of at least 1 GB for systems with up to
five SMA products.
• SMA Solar Technology AG recommends
using an Internet flat rate with a monthly data
volume of at least 3 GB for systems with up to
50 SMA products.
DHCP Server is recommended.
The DCHP server automatically assigns the
appropriate network settings to your nodes in the
local network. A manual network configuration is
therefore not necessary. In a local network, the
Internet router is usually the DHCP server. If the IP
addresses in the local network are to be assigned
dynamically, DHCP must be activated in the Internet
router (see the Internet router manual).
In networks where no DHCP server is active, proper
IP addresses must be assigned from the free address
pool of the network segment to all network
participants to be integrated during commissioning.
