Operating manual EDML-10-BE-en-13 9
DANGER
Danger to life due to electric shock from touching an ungrounded product in
the event of an error
A product that is not grounded may be energized in the event of an error. Touching an
ungrounded product results in death or serious injury due to electric shock in the event of an
error.
• Ensure that the product is integrated in the existing surge protection.
• Ground the enclosure of the product.
• Ensure that the voltage of the digital input does not exceed 30VDC with respect to ground
potential.
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
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation. Touching hot enclosure parts can
result in burn injuries.
• Do not touch the enclosure during operation.
• Wear suitable personal protective equipment.
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.

2 Safety SMA Solar Technology AG
Operating manualEDML-10-BE-en-1310
NOTICE
Manipulation of system data in 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 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
Failure and damage of product and system by interrupting the supply voltage
If the supply voltage of the product is interrupted during operation or a firmware update, a
failure of the product or the entire system may occur. This may result in loss of external setpoints
and a non-permitted starting behavior of the system. In addition, the device can be irreversibly
damaged.
• Ensure that the supply voltage of the product is never interrupted during operation. To do
this, use an uninterruptible power supply with 7 minutes bridging time.
Electrical installations (for North America)
All installations must conform with the laws, regulations, codes and standards applicable in the
jurisdiction of installation (e.g. National Electrical Code® ANSI/NFPA 70 or Canadian
Electrical Code® CSA-C22.1.).
• Before connecting the product to the utility grid, contact your local grid operator. The
electrical connection of the product must be carried out by qualified persons only.
• Ensure that the cables or conductors used for electrical connection are not damaged.
IP addresses of Modbus devices
In systems with Modbus devices, static IP addresses must be assigned to all Modbus devices.
Suitable IP addresses can be assigned to the Modbus devices from the free address supply of
the network segment either manually or dynamically via DHCP.
If the IP addresses are to be assigned dynamically, DHCP must be activated in the router (see
the router manual). Make sure that the Modbus devices do not contain variable IP addresses
but always the same IP addresses (static DHCP).
This also applies to data managers that are used as subordinated devices (slaves).

2 Safety
SMA Solar Technology AG
Operating manual EDML-10-BE-en-13 11
IP addresses in local networks
In local networks in which no DHCP server is active, suitable IP addresses from the free
address pool of the network segment must be assigned to all nodes to be integrated during
initial commissioning.
If the IP addresses in the local network are to be assigned dynamically, DHCP must be
activated in the router (see the router manual). The DCHP server automatically assigns the
appropriate network settings to your nodes in the local network. A manual network
configuration is therefore not necessary.
Completion of data after interruption of communication
If the data communication between the Data Manager and SMA products connected via
SMA Speedwire is interrupted, the data will be retrieved subsequently for the time of the
interruption. Data is retrieved with a maximum interruption period of 7 days. Existing data of
newly connected SMA products will not be transmitted until the Data Manager is
commissioned. Historical data of SMA products are only available in the user interface of the
SMA product.
Possible causes for the interruption of the data communication can be:
• Interruptions of the SMA Speedwire connection
• Resetting connected SMA products over a period of several hours
• Voltage supply interruption

is required (not part of the scope of delivery). The Modbus interface is deactivated by default and
must be configured as needed.
The Modbus interface of the supported SMA products is designed for industrial use – via SCADA
systems, for example – and has the following tasks:
• Remote query of measured values
• Setpoint specifications for system control
For the communication with connected Modbus devices, predefined Modbus profiles and user-
created Modbus profiles can be used. User-created Modbus profiles can be exported and
transferred to another product.
Modbus TCP
The product supports the SMA Modbus profile via the interface of the Modbus client (Modbus TCP)
(see technical information "SMA Modbus® Interface - SMA DATA MANAGER").
SunSpec Modbus
The product supports the standardized SunSpec Modbus profile via the interface of the Modbus
client (Modbus TCP/RTU). The SunSpec Modbus profile from the SunSpec Alliance contains a
comprehensive set of measured values and parameters for Modbus devices in decentralized power
generation systems (e.g. inverters, energy meters, weather stations). The product has data points of
the SunSpec Alliance and therefore conforms with the SunSpec Modbus profile of the underlying
specification version (see www.sunspec.org). Connected Modbus devices compatible with the
SunSpec Modbus profile are automatically integrated into the system with the appropriate Modbus
profile.
Plant-wide parameterization
You can use the system parameter assistant to change the parameters of connected devices at the

Zero export
Some grid operators permit connection of PV systems only on condition that no active power is fed
into the utility grid. The PV energy is therefore consumed exclusively at the place where it is
generated.
When specifications at the point of interconnection are actively controlled, this product enables the
limitation the active power feed-in for the connected SMA inverters and of third-party inverters to
0% as long as these are connected via SunSpec Modbus and support this function.
Reactive power control
The reactive power control can take place through direct parameter settings (Q, cos φ) in the
installation assistant or a variable specification from the grid operator via the Modbus interface or
via analog signals. The reactive power control as characteristic curve function can also be
regulated as a function of the voltage at the point of interconnection Q(V). The values are specified
as a percentage of the maximum AC power. A proper meter for measuring the relevant electrical
variables (V, P, Q) is required at the grid-connection point. A pure voltage measurement is not
sufficient. A suitable energy meter is also required at the point of interconnection for cos φ
specifications in control mode.
