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.
Make sure you keep the jumper for controller maintenance or replacement operations
so you can short-circuit the S1/S2 auxiliary terminals. Extra jumpers can be obtained
quoting Cat. No. 037508 from the Legrand catalogue.
