The IN terminals are used for measurement of earth fault current.
Setpoint: Im3/ErFlCurCTs
Group Basic settings
Range [units] /5, /1 [A]
Related FW 3.0
Description Nominal current of the secondary side of the current transformer connected to
the controller terminals labeled IN. The primary side is adjusted by setpoint
Im3/ErFlCurCTp.

The IN terminals can be used either for measurement of earth current or mains
current (mains import). See also the setpoint

The CT secondary nominal current is adjustable only in IG-NTC and IS-NT. The
IG-NT has the CT secondary nominal current adjusted fixedly to 5A regardless of
this setpoint.
Setpoint: VT ratio

Description The setpoint is used to adjust the generator voltage transformers ratio.
N
OTE
Adjust the setpoint to the value of 1.0 if the generator voltage is connected directly
to the controller terminals, i.e. without transformers.
