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VDC in relation 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

2 Safety
SMA Solar Technology AG
Operating manual EDML-10-BE-en-10 11
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
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.
IP addresses in local networks
In local 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.
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.

Grid management services
The product is equipped with service functions for grid management.

4 Product Overview SMA Solar Technology AG
Operating manualEDML-10-BE-en-1020
Depending on the requirements of the grid operator, you can activate and configure the functions
(e.g. active power limitation) via operating parameters.
The setpoints from the grid operator can either be implemented via open-loop control or closed-
loop control. For this, the setpoints are specified via Modbus, via analog or digital signals or
manually in the installation assistant. The implementation of the setpoints is reported back to the
grid operator.
Active power limitation
The setpoint for active power limitation is specified in percent. The total system power is taken as
the reference value. For this, the setpoints are specified via Modbus, via analog or digital signals or
manually in the installation assistant.
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.
This product enables the limitation of the active power feed-in of the connected SMA inverters and
inverters of other manufacturers, provided these are connected via SunSpec Modbus and support
this function, to 0% with active closed-loop control of specifications at the grid-connection point.
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 grid-connection point 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.
Direct marketing
A direct marketer can use the product for remotely controlling the system via the built-in direct
marketing interface. In this process, control signals of the direct marketer are transferred to the
system. The function is activated via the installation assistant of the grid management services in the
product.
