ser interface
The inverter is able to provide information about its operation through the
following instruments:
• Warning lights (luminous LEDs)
• LCD display showing operating data
• Mobile app and webserver
• Data transmission on the dedicated RS-485 serial line. The data can be
collected by a PC or a data logger equipped with an RS-485 port. Con-
tact the ABB support service with any queries about device compatibility.
M
easurement tolerance
The data supplied by the inverter may differ from measurements taken
by certified measuring instruments (e.g. output meters, multimeters and
grid analysers); since the inverter is not a measuring instrument it has
wider tolerances for the measurements it makes.
The tolerances are generally:
±5% for real-time measurements with output power below 20%
±3% for real-time measurements with output power above 20%
±4% for all statistical data.
