5 COMMUNICATION
5.1 DB9 COMMUNICATION PORT
The RS232 port is a plug-in interface port, which enables advanced communication between the UPS and
the computer via serial cable (fig. 5.1) and UPS monitoring software.
The interface port is already operative in stand-by mode (see section 4.4.9).
To change settings of the unit, we strongly recommend to be sure that the unit is in stand-by mode. Some
settings can only be changed if the UPS operates in bypass or stand-by mode.
NOTE
The change of some settings can cause the unit to switch from bypass to standby and
output power is lost.
For more information regarding possible settings, please refer to the “Help” manual of the UPS monitoring
software.

5.2 SNMP INTERFACE CARD (OPTION)
This card allows the data interface to be connected directly to an Ethernet network. The card is fitted into the
SNMP Card slot (8, fig. 3.3.5.a). For more information, please refer to the user manual that comes with the
interface card.
6
OPTION: EXTENDED RUNTIME
Extended runtime can be obtained by connecting a separate battery extension pack to the UPS. In this case
the UPS must be informed about the new total battery capacity to allow a reliable recalculation of the
available runtime (via UPS monitoring software). Depending of the charge condition of the new batteries the
new runtime calculations may temporarily be unreliable.
Additional batteries increase the recharging time for the unit; all other operational information is the same as
for standard models.
