This document is valid for the
SMA Energy Meter* (EMETER-10.GR1)
from firmware version 1.02.04.R.
Only qualified persons with the following skills
are allowed to perform the tasks described in this
document:
• Training in the installation and commissioning
of electrical devices

The Energy Meter is a measuring device which
detects electrical measured values at the connec-
tion point and makes them available via Speed-
wire.
The Energy Meter is for private use only.
This product is NOT an energy meter for the con-
sumption of active power as defined in the EU Di-
rective 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 devi-
ate 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 trans-
formers must be connected to the Energy Meter.
The Energy Meter is designed for indoor use on-
ly.
The Energy Meter is approved for use in all EU
member states. Only use the Energy Meter in ac-
cordance with the information provided in the en-
closed 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 ex-
plicitly recommended or distributed by SMA So-
lar Technology AG for this product. Any use of
the product other than described in the Intended
Use section does not qualify as appropriate us-
age. 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.

• 1 x Energy Meter (EMETER-10.GR1)
• 1 x installation manual
Contact your distributor if the scope of delivery is
incomplete or damaged.
Status LED ( ):
• Glowing green:
Energy Meter is switched on.
• Flashing green slowly:
Energy Meter starting up.
• Flashing green fast:
firmware update running.
• Glowing or flashing red or orange:
an error has occurred. Refer to Section "Trou-
bleshooting".
Speedwire LED ( ):
• Off: no Speedwire connection established
• Glowing green: Speedwire connection es-
tablished.
• Flashing green: Energy Meter is sending or
receiving data.
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.
The following figure shows a connection exam-
ple. For exact connection specifications, contact
your electric utility company.
Procedure:
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-sec-
tion 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.
Additionally required material (not includ-
ed in the scope of delivery):
☐ 3 x current transformer
☐ Connection cables for current transformers

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 envi-
ronment and keep it away from liquids.
• Install the Energy Meter in the switch
cabinet only and ensure that the connec-
tion areas for the line conductors and
the neutral conductor are behind a cov-
er 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 clear-
ance between the network cable and
live installation components, or use suit-
able 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 net-
work 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.

DANGER
Danger to life due to electric shock if
external disconnect switch is missing
Lethal voltages are present in the live com-
ponents of the Energy Meter.
• Install an external disconnect switch be-
tween the Energy Meter and the grid-
connection point. The external discon-
nector 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

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 con-
nected 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.
Electrical Connection for Applications
> 63 A
Recommendations for the current trans-
former
SMA Solar Technology AG recommends cur-
rent transformers designed for a secondary
current of 5 A. The current transformers
should have at least accuracy class 1.
