Bypass:
In the event of a fault (e.g. overtemperature or overload),
the bypass module protects the internal electronics against
irreparable damage. In the event of a fault, the load supply
is automatically switched to bypass mode and the loads are
supplied with power from the building’s normal mains sup-
ply
WITHOUT battery back-up. This operating state is indi-
cated on the front panel and in the form of information via
the software.

7.2 Interface connections
With the XANTO RT series, the back panel of the UPS system
is equipped with a DB9-port and a slot for optional interface

The DB9-socket supports communication on the basis of the
RS-232 protocol as well as the use of dry contacts.
These connections enable the following:
•
Monitoring of the UPS system,
•
Monitoring of the input voltage,
•
Automatic data back-up,
•
Computer shutdown and
•
UPS system shutdown.
These functions are supported by the DataWatch software,
which is included in the scope of supply.
