1.1.3 Customer Interface
•
Building Alarm Monitoring – Up to five inputs in the UPS are available to connect the facility’s alarm
system contacts. Some system configurations may limit the number of inputs available. The UPS
uses these inputs to monitor the building alarms in addition to the UPS status. See Chapter 8:
“Communication” for additional information.
•
Alarm Contact – One alarm contact is provided for connection to equipment at the facility, such as
a light, an audible alarm, or a computer terminal. The equipment connected to this contact alerts
you to a UPS alarm. See Chapter 8: “Communication” for additional information.
•
X-Slot Communication Bay – A four-slot communication bay is provided as a standard feature. Four
optional X-Slot cards can be installed in the UPS module at any time. See Chapter 8:
“Communication” for additional information.
•
ConnectUPS -X Web/SNMP Card – This X-Slot card is provided as standard equipment and
provides remote monitoring through a Web browser interface, e-mail, and a network management
system (NMS) using SNMP. See Chapter 8: “Communication” for additional information.
1.1.4 Advanced Battery Management
A three-stage charging system increases battery service life by optimizing recharge time, and protects
batteries from damage due to high current charging and inverter ripple currents. Charging at high
currents can overheat and damage batteries.
1.1.5 Power Management Software
Eaton LanSafe® Power Management Software is bundled as part of the Software Suite CD shipped
with the UPS. See Chapter 8: “Communication” for additional information.
1.2 Options and accessories
Contact an Eaton sales representative for information about the following options.
1.2.1 Integrated battery cabinet
Battery backup protection can be enhanced by equipping the UPS system with up to four Eaton 9395
battery cabinets containing sealed lead-acid, maintenance-free batteries. The battery cabinet is
available in one size, with a 240-cell configuration. The cabinets are designed for line-up-and-match
installation, but may be installed separate from the UPS cabinet.
1.2.2 Field Installed UPM
A Field Installed UPM (FI-UPM) provides N+1 redundancy for the UPS system. The FI-UPM may be
installed at any time in the future when power needs change. The module cabinet is installed on the
left side of the UPS and is wired directly to the UPS. No input or output wiring changes are needed for
redundancy. Operation remains the same as for the original UPS.
1.2.3 Maintenance Bypass Module
The Maintenance Bypass Module (MBM) enables power to completely bypass and isolate the UPS so
that the UPS can be safely serviced or replaced without interrupting power to critical systems.
