Standard
three-phase
installation

Q1 - The installer has to provide an external disconnection device; this breaker has to be easily reachable
and identified as "disconnection device".

( ) - See note in the box in the upper right corner of the wiring diagrams.

( ) - The value has to be calculated according to the VT used.

NOTE:

The transformer VT is used:

- To isolate the controller aux circuit from the main circuit.

- When coil voltage of the contactors are different from the main voltage network.

(1) Setting polarity of CT current in Advanced Menu A.02
(2) On wrong connection, the measured Cos

remain constant when we switch on the banks.

It is necessary to change the connection of CT before to connect it to a phase or a signal.
