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.

Turn off power before making line voltage connections
Mount the Fronius Smart Meter (see "Mounting")
Connect circuit breakers or fuses and disconnects (see "Circuit Protection")
Connect the line voltage wires to the meter's terminal block (see "Line Wiring")
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")
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")
Check that the CT phases match the line voltage phases (see "Connect Current
Transformers")
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")
If necessary set terminating resistors (see "Terminating Resistors")
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 "Operation").
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.
Set CT-Ratio and Grid Type on the web interface of the Fronius Datamanager in Set-
tings - Meter - Settings (see "Configuration web interface")
