Information on Connection and Commis­sioning

The line conductor L1 supplies the Energy Meter
with power. At least the line conductor L1 and
the neutral conductor must be connected for the
Energy Meter to switch on.

DANGER

Danger to life due to electric shock if
external disconnect switch is missing

Procedure:

DANGER

Danger to life due to electric shock

Lethal voltages are present in the switch
cabinet.

• Disconnect the connection point from
voltage sources and make sure it cannot
be reconnected.

• Ensure that the conductors to be con­nected to the Energy Meter are free of
voltage.

WARNING

Fire hazard

If a fuse is missing or incorrect and a fault
oc curs, a fire ma y be caused. Thi s can result
in death or serious injury.

•Protect the line conductors of the
EnergyMeter with a fuse or a main/
selective circuit breaker, max. 63 A.

1. Mount the Energy Meter on the top-hat rail.
Hook the Energy Meter into the top edge of
the top-hat rail and press down until it snaps
into place.

Intended Use

The Energy Meter is a measuring device which
detects electrical measured values at the connec­tion point and makes them available via Speed­wire.

The Energy Meter is for private use only.
This product is NOT an energy meter for the con­sumption of active power as defined in the EU Di­rective 2004/22/EC (MID). The Energy Meter
must not be used for billing purposes. The data
collected by the Energy Meter relating to the
power generated by your PV system may devi­ate from the data of the main Energy Meter.
The Energy Meter must only be connected to the
subdistribution of the household on the load side
behind the Energy Meter of the electric utility
company. For applications > 63 A, current trans­formers must be connected to the Energy Meter.

The Energy Meter is designed for indoor use on­ly.

The Energy Meter is approved for use in all EU
member states. Only use the Energy Meter in ac­cordance with the information provided in the en­closed documentation. Any other use can result
in personal injury or property damage.

For safety reasons, it is not permitted to modify
the product or install components that are not ex­plicitly recommended or distributed by SMA So­lar Technology AG for this product. Any use of
the product other than described in the Intended
Use section does not qualify as appropriate us­age. It is prohibited to make any modifications
that are not approved by SMA.

The enclosed documentation is an integral part
of the product and must be read and observed.
Keep in a convenient place for future reference.

Safety Precautions

DANGER

Danger to life due to electric shock

Lethal voltages are present in the live
components.

• Only use the Energy Meter in a dry envi­ronment and keep it away from liquids.

• Install the Energy Meter 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.

• Disconnect the Energy Meter from
voltage sources before cleaning. The
Energy Meter must be cleaned with a
dry cloth only.

• Observe the prescribed minimum clear­ance between the network cable and
live installation components, or use suit­able insulation.

WARNING

Danger to life due to electric shock

If network cables are laid outdoors, they
may be subject to overvoltages, e.g. due to
flash of lightning. This can result in death or
serious injury.

• Network cables laid outdoors must be
suitably protected from overvoltage.

NOTICE

Damage to or destruction of the
Energy Meter if connected to ISDN

• Do not connect an ISDN cable to the net­work terminal of the Energy Meter.

Damage to or destruction of the
Energy Meter due to inappropriate use

• The Energy Meter must not be operated
beyond the values specified in the technical
data.

Procedure:

DANGER

Danger to life due to electric shock

Lethal voltages are present in the subdistri­bution of the household.

• Disconnect the connection point from
voltage sources and make sure it cannot
be reconnected.

• Ensure that the conductors to be con­nected to the meter are free of voltage.

WARNING

Fire hazard

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
Energy Meter with a fuse or a main/se­lective circuit breaker switch, max. 63 A.

1. Connect one current transformer to each line
conductor L1, L2 and L3.

2. On each current transformer, connect one
connection cable for current measurement to
each of the secondary current terminals
(k/S1 and l/S2). Observe the permitted con­nection cross-section of the Energy Meter (see
Section "Technical Data"):

3. Connect the connection cables for current
measurement to the Energy Meter. Observe
the prescribed torque for screw terminals (see
Section "Technical Data"):

4. Connect the connection cables for voltage
measurement to the Energy Meter. Observe
the prescribed torque for screw terminals (see
Section "Technical Data"):

5. Connect the connection cables for voltage
measurement to the corresponding line con­ductors.

Network Terminal

IGMP protocol from version 2 must be
supported

The Energy Meter works with Multicasts. For
the correct function of the Energy Meter, all
network devices used must support the IGMP
protocol, minimum required version 2
(IGMP V2).

Additionally required material (not includ­ed in the scope of delivery):

☐ 1 x network cable

Recommended cable types:

• SF/UTP, S-FTP, S/UTP, SF/FTP, S/FTP, S-STP
For further information on cable types, refer to

the Technical Information "SMA Speedwire
Fieldbus" at www.SMA-Solar.com.

Procedure:

1. Connect the network cable to the network ter­minal (Speedwire) of the Energy Meter.

2. Connect the other end of the network cable to
a router/network switch. SMA products
which are to receive measured values must be
integrated in the same local network.

Commissioning

1. Cover the Energy Meter with the cover or the
contact protection of the subdistribution.

2. Switch the power supply to the subdistribution
back on.

☑The LEDs of the EnergyMeter glow during

start-up. If there is only one Energy Meter in
the system, the Energy Meter connects
automatically to SMA communication
products in the same local network. For more
information on commissioning, see the user
manual of the supported devices.

✖ The LEDs are not glowing or the

Energy Meter is not displayed by the SMA
communication products?

• Correct the error (see Section "Trouble-

shooting").

Resetting the Energy Meter to
Default Settings

Procedure:

• Press the reset button with a sharp object and
hold it for two to six seconds.

Restarting the Energy Meter

Procedure:

• Press the reset button with a sharp object and
hold it for six seconds or longer.

Accessing the User Interface

Procedure:

1. Call up the Internet browser and in the ad­dress line enter

http://energymeter“Serial number“.local,

e.g.:
http://energymeter7435667356.local
Note: The serial number can be found on the

type label of the Energy Meter.

2. Press Enter.

☑ The user interface of the Energy Meter opens.
✖ The user interface does not open?

• Correct the error (see Section "Trouble-

shooting").

Configuring the Current Transformer

Procedure:

1. Open the user interface of the Energy Meter
(see Section "Accessing the User Interface")

2. On the homepage, select Device settings >
Current Transformer settings.

3. Activate the checkbox
Use Current Transformers.

4. Enter the required transformation ratio in the
field Current Transformer ratio.

5. Select [Apply].

.

Performing a Firmware Update

Procedure:

1. Download the update file from
www.SMA-Solar.com and save it to your
computer.

2. Open the user interface of the Energy Meter
(see Section "Accessing the User Interface")

3. Follow the instructions in the menu

Firmware update.

Procedure after Replacing an
Energy Meter

Procedure:

• If more than one Energy Meter is installed in
your system and you have replaced one or
more Energy Meters, you will need to adjust
the serial number of the corresponding
Energy Meter in the Sunny Island/Sunny Boy
Smart Energy. This will avoid inaccurate me­ter reading data in the Speedwire data mod­ule Sunny Island/Sunny Boy Smart Energy:
– In systems without Sunny Home Manager,

enter the serial number of the
Energy Meter via Sunny Explorer in the
Sunny Island/Sunny Boy Smart Energy
(for information on changing device pa­rameters, see user manual of the Sunny Ex­plorer).

– In systems with Sunny Home Manager,

configure the Energy Meter in
Sunny Portal (see user manual of the
Sunny Home Manager).
