Web/SNMP Module (optional)
The module supports HTTP and SNMP compliant remote monitoring and shutdown for
the protected computer systems. It can be connected to a twisted-pair Ethernet network
(10/100BaseT) using an RJ4 connector.
The Web/SNMP module has a build-in switching hub that allows three (3) additional network
devices to be connected to the network without the requirement of additional network drops.
In addition, an Environmental Monitoring Probe (EMP) can be requested from the UPS
manufacturer to obtain humidity, temperature and two relay inputs. It is connected to the
communication port of the Web/SNMP module as option.

AS/400 Relay Module (optional)
The Relay Module provides potential free relay interface for AS/400 connected computers and
industrial applications. The relay interface supports both 1-pin D-sub connector and terminal
block connections up to four (4) potential free relays.
The relay contacts are rated for 1 A, 30 Vac or 200 mA, 60 Vdc, and they have a galvanic
isolation from the other circuits of the UPS unit.
