Installation
Installation
Checklist
See the sections referenced below for installation details.
1
Turn off power before making line voltage connections.
2
Mount the Fronius Smart Meter (see
).
3
Connect circuit breakers or fuses and disconnects (see
on page
).
4
Connect the line voltage wires to the meter‘s terminal block (see
page
5
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
on page
6
Connect the twisted white and black wires from the CTs to the terminal block on the
meter, matching the wire colors to the white and black dots on the meter label (see
7
Check that the CT phases match the line voltage phases (see
).
8
Record the CT rated current for each meter, because it will be required during setup.
9
Connect the output terminals of the Fronius Smart Meter to the monitoring equip-
ment (see
Connecting the Data Communication Signals to the Fronius Inverter
).
10
If necessary set terminating resistors (see
on page
).
11
Check that all the wires and plugs are securely installed in the terminal blocks by
tugging on each wire.
12
Turn on the power to the Smart Meter.
13
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
14
Check your Fronius System monitoring software. In order to ensure compatibility
between 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.
15
Set CT-Ratio and Grid Type on the web interface of the Fronius Datamanager in Set-
tings - Meter - Settings (see
).
Mounting
The Fronius Smart meter has two mounting holes spaced 5.375 in. (137 mm) apart (cen-
ter-to-center). These mounting holes are normally obscured by the detachable screw ter-
minals. 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.
