INTRODUCTION AND SYSTEM DESCRIPTION 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 protec

RECTIFIER/POWER FACTOR CORRECTION (PFC) CIRCUIT In normal operation, the rectifier/power factor correction (PFC) circuit converts mains AC power to regulated DC power for use by the inverter, while ensuring that the wave shape of the input current used by the UPS is near ideal. Extracting this sinewave input current achieves two objectives: the mains power is used as efficiently as possible by the UPS, and the amount of distortion reflected on the mains is reduced. This results in clean

The UPStation GXT is equipped with automatic and remote battery test features. The automatic test occurs every 14 days if a manual battery test has not been performed or if mains has not been interrupted (14 day timer resets if unit goes to battery). Should the battery fail this test, the fault indicator along with the A and C diagnostic LEDs will illuminate and an alarm will sound (refer to Troubleshooting Guide). The remote test feature functions with either SiteNet® 2 or SiteNet® SNM

OPERATING MODES NORMAL MODE OPERATION- UPS mode During normal operation, mains power provides energy to the UPS. The filters, the power factor correction circuit and the inverter process this power to provide computer grade power to connected loads. The UPS maintains the batteries in a fully charged state. The four green LED’s indicate an approximate level of load in 25% increments. If the UPS becomes loaded beyond full rating, the fifth (amber) LED indicator will illuminate an

STARTING THE UPS 1. Ensure the load equipment is turned off, and all loads are properly connected to the UPS output. 2. Check that the mains wall isolator is ON. Turn On (Close) the Battery circuit breaker, the Input and Output circuit breakers in that order. The UPS will now automatically start up and default to BYPASS mode once the UPS is connected to an active AC mains supply and the Battery and Input circuit breakers are closed. At the end of the startup sequence the BYPASS LED sho

SWITCHING FROM OUTPUT OFF TO UPS or UPS to BYPASS to OFF 1. If the UPS is in OUTPUT OFF condition, with all rear mounted breakers in the ON position, and the AC input LED and the bottom LED of the BATTERY/LOAD array lit. To go to UPS mode, press the UPS ON/ALARM /BATTERY TEST button until a “Beep” is heard. The UPS will then go through its start-up routine ending up after approximately 10 seconds with the UPS LED lit. 2. If the UPS is operating in UPS mode and there is a need to go to

UPS MONITORING The UPStation GXT UPS has the capability of being monitored with stand alone computers, network workstations, network servers, or UNIX hosts via the DB-9 socket located on the rear of the UPS. This capability is used in applications requiring the UPS to provide status and power monitoring information to the computer system. For example, during a mains power failure, the information can be used by the computer’s operating system or application program to automatically sav

MAINTENANCE The UPStation GXT UPS requires very little maintenance. The batteries are valve regulated, non-spillable, lead acid, and should be kept charged to obtain their designed life. The UPS continuously charges the batteries when connected to the mains supply. When storing the UPS for any length of time, it is recommended to apply power to the UPS for at least 24 hours every four to six months to ensure full recharge of the batteries. In no case should the unit be stored in exces
