Characteristics and technical data
13.
To protect the AC connection line of the inverter, we recommend installing a device for protection against over current and leakage with the following characteristics:
Type Automatic circuit breaker with differential thermal magnetic protection
Nominal Voltage 230 Vac
Nominal Current 20 A 25 A
Magnetic protection characteristic B/C
Number of poles 2
Type of differential protection A/AC
Differential sensitivity 300 mA
ABB declares that the ABB transformerless inverters, in terms of their construction, do not inject continuous ground fault currents and therefore there is no
due to high impedance of the line that connects the inverter to the power supply point.
2) Maximum length of the line conductor (mt)
4 mm² 19 m 16 m 14 m
6 mm² 29 m 24 m 21 m
10 mm² 48 m 41 m 35 m
16 mm² 77 m 65 m 56 m
The values are calculated in nominal power conditions, taking into account: 1. a power loss of not more than 1% along the line. 2. copper cable, with HEPR rubber insulation, laid in free air

Connection of the tachometer signal
The tachometer signal allows the 7200-WIND-INTERFACE-EU to drive the inver-
ter. It is therefore necessary to connect up the two cables from the 7200-WIND-
