Connection
Installation—All Applications
Connect external battery pack(s) to your UPS
4
Your UPS has no internal batteries and must be connected to at least one external
battery pack to operate. Complete installation and mounting instructions for your
battery pack(s) appear in the battery pack(s)'s owner's manual. Make sure that
connection cables are fully inserted into their connectors. Small sparks may result
during battery pack connection; this is normal.
Your UPS will not operate unless connected to a charged external battery pack.
Battery packs are fully charged prior to shipping. However, if your battery pack has
been stored for an extended period, recharge its battery for 8 hours. To charge the
battery pack, turn on the UPS's and isolation transformer's AC input breakers. Your
UPS may not provide its full runtime if the battery pack is not fully charged.
Once the UPS is operating, it will charge its battery pack(s) automatically.
Connect communication cables to your UPS
5
Connecting communications cables to your UPS is optional; your UPS will operate
properly without these connections.
To enable full network monitoring and control of the UPS, use the DB9 cable provided
to connect the UPS's RS-232 port to a computer's DB9 serial port. Install
Tripp Lite's PowerAlert software onto the computer from the CD provided, or
download the most recent version of PowerAlert from www.tripplite.com.
To send and receive basic contact closure signals to and from the UPS, use a contact
closure DB9 cable (user-supplied) to connect the UPS's dry contact port to a computer's
DB9 serial port. See the Dry Contact Interface Table and Diagram to decipher the
signals from this port, or install Tripp Lite's PowerAlert software onto the computer
from the CD provided, or download the most recent version of PowerAlert from
www.tripplite.com.
To install an emergency power off switch, use a RJ11 cable (user-supplied) to connect
the EPO port to a remote switch. The pin assignments for the EPO port are shown
below. If there is a short between pins 2 and 3, 2 and 5, 4 and 5, or 3 and 4, the UPS
will power off.
