Example: Installa-
tion of several in-
verters
Do not ground the
solar modules.
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.
Power Line Com-
munication (PLC)
Transmitter
This inverter is equipped with a Power Line Communication (PLC) Transmitter on the DC
side.
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
To ensure compliance with all regulations applicable in your country and to provide best
reception at the receivers, please follow the recommendations below:
- 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.
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.
