THE
(OPTIONAL) VERSION OF THE UPS SERIES DIFFERS FROM THE STANDARD VERSION IN THAT IT
USES AN ISOLATION TRANSFORMER INSTEAD OF THE BATTERIES.
NOTE:
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 iut and/or output switches.
UPS version with internal transformer is supplied with neutral on secondary circuit not connected to earth. It
shall be bind to earth according with neutral arrangement on the site.
ATTENTION:
Manual By-pass change over operation does not insulate the transformer inside which continue to
supply the load; the personnel operating inside the UPS should be aware that under these conditions
some part are subjected to dangerous voltages
