Controller selection
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 auxiliaries control plate. The same voltage must be used
for the ACP plate, the IVE unit and the circuit-breaker 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.
