Power Module Features
(continued)
Communication Interface
Dry Contacts:
#1 (UPS Normal); #2 (Load On Reserve); #3 (Load On Battery); #4 (Battery Low Voltage);
#5 (Reserve Abnormal); #6 (Battery Test Fail). See “Communications” for details.
Remote “Emergency Power OFF” (EPO) Connector:
This modular jack allows remote emergency
shutdown. See “Communications” for details.
“Smart” RS-232 Interface Port:
This female DB9 port connects the UPS to a workstation or server. It
uses RS-232 communications to report UPS and power conditions. It is used with Tripp Lite software and
cabling. See “Communications” for details.
Ethernet Port & Ethernet Power:
The Ethernet Port is an RS-232 port that accepts an optional RS-232/RJ45
Ethernet Adapter (sold separately). The Ethernet Power connection provides 12VDC power to the
optional adapter. See “Communications” for details.
Generator Contact:
This port connects to an auxiliary power generator. When the generator is operating
to support the equipment load, the UPS System will automatically reduce its charge current by 50% in order
to prevent overloading of the generator. See “Communications” for details.
RS-485 Ports:
These ports allow multiple UPS power modules to be connected in a parallel configuration.
See “Communications” for details.
UPS Parallel Communication Ports:
These ports allow multiple UPS power modules to communicate
while in a parallel configuration. See “Communications” for details.
