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.
MAJOR COMPONENTS Rectifier/PFC INPUT Output Transformer GXT 208X, 230X, & 240X models only Inverter EMI/RFI Filter EMI/RFI Filter OUTPUT Static Bypass Battery Battery Charger 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 utility line and keep the sensitive equipment protected.
STATIC BYPASS The UPStation GXT provides an alternate path for utility power to the connected load, in the unlikely event of a UPS malfunction. Should the UPS have an overload, over temperature, or UPS failure condition, the UPS automatically transfers the connected load to BYPASS providing the bypass voltage is within specification. BYPASS operation is indicated by an alarm and an illuminated BYPASS LED (other LED’s may be illuminated to indicate any diagnosed problem).

OPERATING MODES NORMAL MODE OPERATION- UPS mode During normal operation, utility 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 Leads indicate an approximate level of load in 25% increments. If the UPS becomes loaded beyond full rating, the fifth (amber) LED indicator will illuminate and sound an alarm.
BYPASS MODE OPERATION During BYPASS operation, utility power provides energy to your load and maintains the batteries in a fully charged state. The BYPASS will automatically power the load temporarily during overloads of the inverter, when diagnostics detect equipment problems, or when the operator selects BYPASS operation. The four green LEDs indicate an approximate level of load in 25% increments.
MANUAL OPERATION WITH UTILITY AVAILABLE Under normal circumstances, the UPS will be operated with utility available. The UPS can operate in three possible modes with utility available: NORMAL MODE OPERATION - UPS ON LED will be on and the inverter will provide power to the load. BYPASS MODE OPERATION - BYPASS LED will be on and the bypass will provide power to the load directly from the utility. OUTPUT OFF MODE OPERATION - UPS ON and BYPASS LEDs will be off and the load will not have power.
POWERING DOWN THE UPS WITH UTILITY AVAILABLE 1. Shutdown all connected load equipment. 2. Press the OUTPUT OFF/BYPASS button once until a "beep" is heard. The UPS ON LED will extinguish and the BYPASS LED will light if the BYPASS voltage is within an acceptable range. The load is now powered through the BYPASS and there is no UPS protection. The UPS will remain in BYPASS MODE OPERATION until the user continues with the next step to turn the UPS off. 3.
POWERING UP THE UPS WITHOUT UTILITY 1. Ensure the load equipment is turned off, and all loads are properly connected to the UPS output. 2. Verify that the BATTERY, INPUT, AND OUTPUT circuit breakers remain closed. 3. Press the UPS ON/ALARM/BATTERY TEST button for at least one second until you hear the audible alarm emit a “double beep" to signal acceptance of the command. After a short delay, the BATTERY LED should light.
