Example: Installation Of Several Inverters; Do Not Ground The Solar Modules; Power Line Communication (Plc) Transmitter - Fronius Symo Advanced Series Installation Instructions Manual

When installing the inverter in a switch cabinet or similar closed environment, it is neces-
sary to make sure that the hot air that develops will be dissipated by forced-air ventilation.
If you wish to install the inverter on the outer walls of cattle stables, it is important to keep
a minimum clearance of 2 m between all sides of the inverter and air vents and other
openings.
The place of installation should not be exposed to ammonia, corrosive gases, salts, or
acids.
Example: Installa-
tion of several in-
verters
Do not ground the
solar modules.
Power Line Com- This inverter is equipped with a Power Line Communication (PLC) Transmitter on the DC
munication (PLC) side.
Transmitter The purpose is to provide Rapid Shutdown acc. to NEC Edition 2017 Art. 690.12. The PLC
is implemented according to the Specification "Communication Signal for Rapid Shutdown
- SunSpec Interoperability Specification". Details can be found at www.sunspec.org

Keep distance between DC+ and DC- Conductors as close as possible
Avoid cable loops of excessive cables (coiling).
Use metallic raceways where possible
Do not run DC cables from different inverters in the same raceway or cable tray.

The inverter is designed exclusively for
connection to and use with non-grounded
solar modules. The solar modules must not
be grounded at either the positive or nega-
tive pole.
