EPARATE BYPASS INPUT
(
OPTIONAL
)
THE OPTIONAL
DI
VERSION OF THE UPS SERIES HAS SEPARATE BYPASS AND INPUT LINES.
The UPS series with Separate Bypass allows a separate connection between the input and the bypass lines.
The UPS output is synchronised with the bypass line, in order to avoid incorrect voltage changeovers during the alternate
phases, in case an automatic bypass or a maintenance isolator closure occurs.

THE
OT
(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.
