EPARATE YPASS

THE (OPTIONAL) VERSION OF THE UPS SERIES HAS SEPARATE BYPASS AND INPUT LINES.
The UPS series with separate Bypass ensures a separate connection between the input and bypass lines.
The UPS output is synchronised with the bypass line so as to safeguard against incorrect voltage changeovers in the
alternate phases, in the event of automatic bypass or closing of the maintenance switch (SWMB).

THE (OPTIONAL) VERSION OF THE UPS SERIES DIFFERS FROM THE STANDARD VERSION IN THAT IT
USES AN ISOLATION TRANSFORMER INSTEAD OF THE BATTERIES.
This series of UPS uses an isolation transformer connected to the UPS output terminals.
NOTE: A separate bypass line is supplied on this UPS version.
The transformer is connected to the UPS output terminals, so the values displayed are those of the quantities
measured upstream of the transformer.
The presence of the transformer inside the UPS modifies the system neutral arrangements.
The installation of a remote maintenance bypass parallel to the UPS is incompatible with inclusion of the
transformer. In any event, if the remote maintenance bypass is inserted, make sure, at the time the remote
bypass switch is closed, that the UPS is isolated from the system by opening the input and/or output
switches.
