Eaton 9390 Guide Specification
October 9, 2009
A.
Communications Bay: The UPS shall be equipped with field configurable
communications bays that will accommodate four (4) communication devices
B.
Remote Monitoring:
1.
Optional WEB/SNMP communication capabilities will be available for all
systems.
2.
The UPS shall be able to be monitored remotely via communications devices.
UPS manufacturer shall provide optional communications devices capable of
communicating via various industry standard protocols such as RS232 and
ModBus. Monitoring of UPS status may also be performed through isolated dry
contact Form C relays.
3.
Remote monitoring of the UPS shall also be possible through status indicators
elsewhere in the same facility through a device that replicates these indicators.
The UPS communication capability should be able to integrate into any industry standard
Building Management System (BMS) and/or Network Management System (NMS). The
UPS must also be able to be monitored via any standard Internet browser (i.e. Internet
Explorer and Netscape).
All optional hardware interfaces shall be “Hot-swappable” (UPS maintains power to
critical applications while changing interfaces).
C.
Shutdown:
1.
There shall be a mechanism that provides graceful, orderly, unattended,
sequential shutdown of one or multiple computers powered by one UPS. This
shutdown shall be performed via in-network or out-of-network means. The order
of shutdown shall be user-defined, allowing the maximization of runtime on
battery for more critical systems.
2.
Shutdown of AS/400 computers shall be possible through open-collector relay
contacts or isolated, dry contact, Form-C relays.
3.
The UPS shall also be capable of interfacing with an operating system’s built-in
shutdown routine, e.g. Windows NT. This shall be done through a cable
connection to the optional serial port on the UPS.
D.
Notification:
1.
There shall be a mechanism to send alerts to key personnel via email or SNMP
traps. An alarm notification may also be sent by a network message.
2.
Dial-out to a computer for alarm notification may be performed. The user may
respond by dialing-in to retrieve alarm history and a summary of current meter
status.
3.
Management: A remote battery test may be performed via an Ethernet network.
The UPS shall be tested through invoking a single command.

UPS MODULE PROTECTION
A.
Rectifier/Charger and Bypass protection shall be provided through individual fusing of
each phase.
B.
Battery protection shall be provided by thermal-magnetic molded-case circuit breakers in
each battery cabinet (if standard battery pack is provided) or external protective device
for an external battery.
C.
Electronic current limiting circuitry and fuses in the Inverter circuit shall provide output
protection.
