Installation
Installation
Checklist
See the sections referenced below for installation details
Turn off power before making line voltage connections
Mount the Fronius Smart Meter (see Mounting on page 9)
Connect circuit breakers or fuses and disconnects (see Circuit Protection on page 10)
Connect the line voltage wires to the meter‘s terminal block (see Line Wiring on page
10)
Mount the Current Transformers (CTs) around the line conductors. Make sure the CTs
face the correct direction. An arrow might indicate either the load or the source (public
grid) (see Connect Current Transformers on page 13)
Connect the twisted white and black wires form the CTs to the terminal block on the
meter, matching the wire colors to the white and black dots on the meter label (see CT
Wiring on page 14)
Check that the CT phases match the line voltage phases (see Connect Current Trans-
formers on page 13)
Record the CT rated current for each meter, because it will be required during setup
Connect the output terminals of the Fronius Smart Meter to the monitoring equipment
(see Connecting the Data Communication Signals to the Fronius Inverter on page 14)
If necessary set terminating resistors (see Terminating Resistors on page 15)
Check that all the wires and plugs are securely installed in the terminal blocks by tug-
ging on each wire
Turn on the power to the Smart Meter
Verify that the LEDs indicate correct operation. If there is a consumption of power and
all generated power sources are turned off, then the LEDs from the used phases
should flash green (see Power Status LEDs on page 17).
Check your Fronius System monitoring software. In order to ensure compatibility be-
tween the inverter and the Smart Meter, software must always be kept up-to-date. The
update can be started via the inverter website or via Solar.web.
Set CT-Ratio and Grid Type on the web interface of the Fronius Datamanager in Set-
tings - Meter - Settings (see Configuration Web Interface on page 16)
Mounting The Fronius Smart meter has two mounting holes spaced 5.375 in. (137 mm) apart (center-
to-center). These mounting holes are normally obscured by the detachable screw termi-
nals. Remove the screw terminals to mark the hole positions and mount the meter.
Self-tapping sheet metal screws are included. Do not over-tighten the screws, as long-term
stress on the case can cause cracking.

Circuit Protection The Fronius Smart Meter is considered “permanently connected equipment“ and requires
a disconnect means (circuit breaker, switch or disconnect) and overcurrent protection (fuse
or circuit breaker).
The Fronius Smart Meter only draws 10-30 mA, so the rating of any switches, disconnects,
fuses and / or circuit breakers is determined by the wire gauge, the mains voltage and the
current interrupting rating required.
- The switch, disconnect or circuit breaker must be within sight and as close as practi-
cable to the Fronius Smart Meter and must be easy to operate.
- Use circuit breakers or fuses rated for 20 amps or less.
- Use ganged circuit breakers when monitoring more than one line voltage.
- The circuit breakers or fuses must protect the mains terminals labeled L1, L2 and L3.
In the rare cases where neutral has overcurrent protection, the overcurrent protection
device must interrupt both neutral and ungrounded conductors simultaneously.
- The circuit protection / disconnect system must meet IEC 60947-1 and IEC 60947-3,
as well as all national and local electrical codes.
Line Wiring - Always turn off power before connecting the line voltage inputs to the Fronius Smart
Meter.
- For the line voltage wires, 16 to 12 AWG stranded wire, type THHN, MTW or THWN,
600 V are recommended.
- Do not place more than one wire per screw terminal; use separate wire nuts or termi-
nal blocks if needed.
- Verify that the line voltages match the line-to-line and line-to-neutral values printed in
the white box on the front label.
Connect each conductor to the appropriate phase; also connect ground and neutral (if ap-
plicable). The neutral connection “N“ is not required on delta models but we recommend
connecting it to ground if neutral is not present.
The screw terminal can handle wire up to 12 AWG. Connect each voltage line to the green
terminal block as shown in the following figures. After the voltage lines have been connect-
ed, make sure both terminal blocks are fully seated in the Fronius Smart Meter.
When power is first applied, check that the LEDs behave normally. If you see LEDs flashing
red-green-red-green, the voltage is too high for this model, so disconnect the power switch
immediately!
