Emergency

Power Off

for Tripp Lite UPS Systems

Tripp Lite’s Emergency Power Off (EPO) makes it possible to shut down UPS systems quickly from a remote location during fires, floods or other unexpected crises. It is designed to allow the connection of a user-supplied contact closure on/off switch to an RS-232 cable running between a com- puter and an SU1000RT2U or SU2200RT2U UPS with a serial number that ends in “C1”*.

*Your UPS’s 13-digit serial number appears on a label with a bar code on the back of the unit. Units with serial numbers that end in “00” are not compatible with the EPO.

Connection

Your EPO has one RJ11 connector and two serial connectors. The serial connector that has two cables emerging from it plugs into the RS-232 port of your UPS (see UPS owner’s manual for location). The serial connector that has one cable emerging from it plugs into your computer’s serial port.

The RJ11 connector should be connected to your user-supplied contact closure on/off switch. Bridge the center pins (pins 2 & 3—see diagram ) of this connector to cause your UPS to shut down immediately.
