ON-LINE DOUBLE CONVERSION
Figure 20,21 for the communication port locations.
When the communication cable is installed, power management software can exchange data with
the UPS. The software polls the UPS for detailed information on the status of the power
environment. If a power emergency occurs, the software initiates the saving of all data and an
orderly shutdown of the equipment. The cable pins for the RS-232 communication port are
identified in Figure 22 and the pin functions are described in Table 9.

Connectivity Cards
Connectivity cards allow the UPS to communicate in a variety of
networking environments and with different types of devices. The UPS has one
available communication bay for the following connectivity cards:
●
Web/SNMP Card
- has SNMP and HTTP capabilities as well as monitoring
through a Web browser interface; connects to a twisted-pair Ethernet
(10/100BaseT) network. In addition, a Environmental Monitoring Probe can be
attached to obtain humidity, temperature, smoke alarm, and security
information.
●
Relay Interface Card
- has isolated dry contact relay outputs for UPS status:
Utility failure, Low battery, UPS alarm/OK, or On bypass.
See Figure 20, for the location of the communication bay.
NOTE：
Before installing the connectivity card , please remove the clip from the
bay. Refer to the user’s manual of the appropriate cards.
