Installation
Checklist for
installation
For information about installation, please refer to the sections stated below
1Switch off the power supply before establishing a mains connection
2Mount the Fronius Smart Meter (see "Mounting" on page 8)
3Connect automatic circuit breakers or automatic circuit breakers and disconnectors
(see"Protective circuit" on page 8)
4Connect the mains cable to the Fronius Smart Meter (see "Cabling" on page 9)
5Connect the output terminals of the Fronius Smart Meter to the Fronius system mon-
itoring using a suitable cable (see "Connecting the data communication cable to
the inverter" on page 9)
6If necessary, set terminating resistors (see "Terminating resistors" on page 10)
7Tug on each wire and plug to make sure that they are securely connected to the ter-
minal blocks.
8Switch on the power supply to the Fronius Smart Meter
9Check the firmware version of the Fronius system monitoring. To ensure compatibil-
ity between the inverter and Fronius Smart Meter, the software must always be kept
up-to-date. The update can be started via the inverter website or via Solar.web.
10 If several Fronius Smart Meters are installed in the system, set the address (see
"Setting the address" under "Setting the address of the Fronius Smart Meter" on
page 13)
11 Set the meter location via the Fronius system monitoring web interface under "Set-
tings - Meter - Settings" (see "Configuring the web interface" on page 14)
Mounting The Fronius Smart Meter can be mounted on a 35 mm DIN rail. The housing comprises
2 modules according to DIN 43880
Protective circuit The Fronius Smart Meter is a hard-wired device and requires a disconnecting device (cir-
cuit breaker, switch or disconnector) and overcurrent protection (automatic circuit
breaker).
The Fronius Smart Meter consumes just 10-30 mA, so that the nominal capacity of all
switches, disconnectors, fuses and/or automatic circuit breakers is determined by the
wire gauge, mains voltage and required breaking capacity.
- Switches, disconnectors and circuit breakers must be within sight and located as
close as possible to the Fronius Smart Meter; they must also be easy to use.
- Use automatic circuit breakers that are rated for max. 63 A.
- To monitor more than one mains voltage, use connected automatic circuit breakers.
- The automatic circuit breakers must protect the mains terminal, which is marked L1.
In rare cases where the neutral conductor has overcurrent protection, the overcur-
rent protection device must interrupt both neutral and non-earthed cables concur-
rently.
- The circuit protection/disconnecting device must satisfy the requirements of IEC
60947-1 and IEC 60947-3, as well as all national and local regulations for electrical
systems.
