GENERAL DESCRIPTION
1.1
Introduction
Congratulations on your choice of the UPStation GXT™ Uninterruptible Power System (UPS). It provides conditioned
power to microcomputers and other sensitive electronic equipment.
Upon generation, AC power is clean and stable. However, during transmission and distribution it may be subject to
voltage sags, spikes, or complete power failure, which may interrupt computer operations, cause data loss, or even
damage equipment. The UPStation GXT protects equipment from these disturbances.
The UPStation GXT is an “on-line” UPS that continuously conditions and regulates its output voltage, whether the
mains power is present or not. It supplies connected equipment with clean sinewave power. Sensitive electronic
equipment operates best from sinewave power. The GXT 3x1 -230X models have an additional output isolation
transformer.
For ease of use, the UPStation GXT contains a light emitting diode (LED) display to indicate either “load percentage” or
“battery capacity” depending upon the mode of operation. It also provides self-diagnostics, a combination On/Alarm
Silence/Manual Battery Test button, a combination Off/Bypass button, and two levels of alarms when the unit is
operating on battery.
The UPStation GXT has an interface port for communications between the UPS and a LAN server or other computer
system. This port provides detailed operating information including voltages, currents, and alarm status to the host
system when used in conjunction with the SiteNet® 2 software. SiteNet® 2 software can also remotely control UPS
operation.

EMI/RFI filters
These UPS components provide surge protection, and filter both electromagnetic interference (EMI) and radio
frequency interference (RFI). They minimize any surges or interference present in the mains line and keep the sensitive
equipment protected.
