IMPORTANT!
Further information on successful start-up.
Observe the following information on connecting the data communication line to
the inverter.
- Use a CAT5 type cable or higher.
- For data lines belonging together (D+, D- and M1+, M1-) use a twisted pair of
cables.
- If the output cables are close to the mains wiring, use wires or cables rated
at 300 V to 600 V (never less than the operating voltage).
- Use double insulated or sheathed output cables when near bare conductors.
- Use shielded twisted pair cables to avoid interference.
- The outputs of the Fronius Smart Meter are galvanically isolated from dan-
gerous voltages.
