NOTE!
-
The antenna can be installed horizontally on the inverter housing sides or
vertically on the bottom of the inverter.
If several inverters are arranged next to each other with horizontally-mounted
antennas, proper spacing between the inverters should be maintained.
-
You should only use the 3/4 in. knockouts provided on the inverter for anten-
na installation.
In addition, you should only use the antenna screw joint provided in the Fro-
nius SolarCity card scope of supply to ensure leak-tightness.
-
If plastic dividers are used in the inverter to separate AC/DC cables and data
communication wires, the data communication wire and the antenna cable
must be laid over the plastic dividers.
-
Follow all information in the operating instructions, safety rules and safety in-
structions for the respective inverter.
