Notes on Laying Data Communication Cables
Laying Data Com-
munication Ca-
bles
IMPORTANT! The inverter must not be operated with one option card and 2 knocked-out
option card slots.
In this case Fronius provides an appropriate dummy cover as an accessory:
42,0405,2020 ... for Fronius Primo 3.8–8.2
42,0405,2094 ... for Fronius Primo 10.0–15.0
IMPORTANT! If data communication cables are wired into the inverter, observe the follow-
ing points:
- Provide separate conduits for data communication cables
- Lay data communication cables in the supplied protective hose
- Knock out the appropriate opening
- Cleanly deburr the knocked-out opening
- Fronius Primo 3.9–8.2 only:
Insert the supplied cable gland into the opening (if both openings are knocked out, an
additional cable gland 42,0405,2019 is required)
- Clip the inverter onto the wall bracket
- Guide the data communication cables through the cable glands from behind
- When pivoting the inverter, ensure that the cables are not trapped, kinked, or dam-
aged in any other way. Do not loop the data communication cables.
- Lay the data communication cables in the data communication area of the inverter and
connect to the Solar Net "IN" and "OUT" connections.
Plug the termination plugs into the remaining Solar Net connections.
