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.

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).
