ATTENTION! ?
More information on successful commissioning.
Note the following information about connecting the data communication cable to the
inverter.
▶
Use cables of type CAT5 or higher.
▶
Use a mutual twisted cable pair for data lines that belong together (D+, D- and M1+,
M1-).
▶
If the output cables are close to the mains cabling, use wires or cables that are
designed for 300 V to 600 V (never less than the operating voltage).
▶
Use double-insulated or sheathed output cables when they are close to bare con-
ductors.
▶
Use shielded twisted pair cables to avoid faults.
▶
The outputs of the Fronius Smart Meter are electrically isolated from hazardous
voltages.
