Installation
Checklist for
installation
For installation information, see the following chapters:
1
Switch off the power supply before establishing a mains connection.
2
Mount the Fronius Smart Meter TS (see Installation on page 17).
3
Connect automatic circuit breakers or automatic circuit breakers and disconnectors
(see Protective circuit on page 17).
4
Connect the mains cable to the Fronius Smart Meter TS (see Cabling on page 18).
5
Mount the current transformers on the conductors. Make sure that the current trans-
formers are pointing in the correct direction. An arrow either points to the load or the
source (public grid) (see Connecting the current transformers on page 21).
6
Connect the current transformer and Fronius Smart Meter TS (see Connecting the
current transformers on page 21).
7
Make sure that the current transformer phases match the mains voltage phases (see
Connecting the current transformers on page 21).
8
Note down the nominal current of the current transformer for each meter. These val-
ues will be required during setup.
9
Connect the data communication connections of the Fronius Smart Meter TS to the
Fronius system monitoring (see Connecting the data communication cable to
the inverter on page 22).
10
If necessary, set terminating resistors (see Terminating resistors on page 23).
11
Tug on each wire and plug to make sure that they are securely connected to the ter-
minal blocks.
12
Switch on the power supply to the Fronius Smart Meter TS.
13
Check the firmware version of the Fronius system monitoring. To ensure compatibil-
ity between the inverter and the Fronius Smart Meter TS, the software must always
be kept up to date. The update can be started via the inverter web page or using
Solar.web.
14
Set the transformation ratio of the current and voltage transformers (see Setting the
transformation ratio of the current and voltage transformers on page 27).
15
If several Fronius Smart Meter TS are installed in the system, set the address (see
"Setting the address" under Setting the address on the Fronius Smart Meter TS
on page 28).
16
Configure and commission the meter (see Start-up on page 31).
Installation The Fronius Smart Meter TS can be mounted on a 35 mm DIN rail. The housing com-
prises 3 modules according to DIN 43880.
Protective circuit The Fronius Smart Meter TS is a hard-wired device and requires a disconnecting device
(circuit breaker, switch or disconnector) and overcurrent‑protection (automatic‑circuit
breaker).
The Fronius Smart Meter TS consumes 10 - 30 mA, the nominal capacity of the discon-
necting devices and the overcurrent‑protection is determined by the wire thickness, the
mains voltage and the required breaking capacity.
