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.

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.

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
Lethal voltages are present in the live components of the Energy Meter.
• Install an external disconnect switch between the Energy Meter and the gridconnection point. The external disconnector must be close to the
Energy Meter and easily accessible.
Complete Multicast support required
Incomplete Multicast support of individual network components can lead to malfunction of the Energy Meter.
Electrical Connection for Applications
< 63 A
The following figure shows a connection example. For exact connection specifications, contact your electric utility company.
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 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, 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.
2. Connect the conductors to the Energy Meter.
Observe the permitted connection cross-section and torque for screw terminals (see Sec-
tion "Technical Data"):
• In a three-phase utility grid, connect the line conductors L1, L2 and L3 and the neutral conductor to the Energy Meter in accordance with the wiring diagram.
• In a single-phase utility grid, connect the line conductor L1 and the neutral conductor to the Energy Meter in accordance with the wiring diagram.
Electrical Connection for Applications
> 63 A
Additionally required material (not included in the scope of delivery):
☐ 3 x current transformer
☐ Connection cables for current transformers
Recommendations for the current transformer
SMA Solar Technology AG recommends current transformers designed for a secondary current of 5 A. The current transformers should have at least accuracy class 1.

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):
