All external connections must be via the terminal boards and the input strip on the FAR-
Q cabinet.
- It is necessary to install a current transformer in order to start (normally In / 5 A) in
accordance with the total current of the installed receivers. The current
transformer secondary line must have the appropriate diameter in terms of its
distance from the regulator (minimum 2.5 mm
2 ).
- The power supply voltage for the regulator is between phases (except when it is a
special single-phase regulator). Voltage must be taken from the two phases
where there is no current transformer. The phase where the current transformer
is installed does not coincide with any of the phases from which voltage is being
taken to supply the regulator.
- The current transformer is installed at a point where all of the load currents to be
corrected plus the capacitor current are passing.
CORRECT INCORRECT
CORRECT
The current transformer has to
be in front of the bank and the
receivers (motors, etc).
S1

T.C.
INCORRECT
- No capacitor will be
connected because the current
transformer does not give any
signal.
- Check that the CT is not
short circuiting or installed
outside the loads.

T.C.
INCORRECT
- All capacitors in the bank are
connected, but do not
disconnect when the load
decreases. Risk of
overcorrecting the system
without a load.
