Source-changeover systems
Associated controllers
By combining a remote-operated source-changeover
system with an integrated BA or UA automatic
controller, it is possible to automatically control source
transfer according to user-selected sequences.
These controllers can be used on source-changeover
systems comprising 2 circuit breakers.
For source-changeover systems comprising 3 circuit
breakers, the automatic control diagram must be
prepared by the installer as a complement to to
diagrams provided in the “electrical diagrams” section
of this catalogue.

(1)
For example, 220 V single-phase or 220 V three-phase.
(2)
The controller is powered by the ACP control plate. The same voltage must be used for the
ACP plate, the IVE unit and the operating mechanisms. If this voltage is the same as the source
voltage, then the “Normal” and “Replacement” sources can be used directly for the power supply.
If not, an isolation transformer must be used.
