I – Connecting the current transformer (CT):
 The CT should be positioned on phase L1 of the installation to be compensated, upstream of all
the receivers to be compensated and the capacitor bank.
 It is connected as follows:
 Terminals S1 & S2 are supplied short-circuited by a jumper.
 Connect the CT cable terminals, then remove the jumper so the controller works via
the CT.
 If work or maintenance is being carried out on the CT, repeat these steps in reverse
order.
 The CT can be positioned in 3 different ways depending on the type of installation:
 Installation with one transformer:
