    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.

    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.

    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.

    BYPASS MODE OPERATION During BYPASS operation, mains power provides energy to your load and maintains the batteries in a fully charged state. The four green LED’s indicate an approximate level of load in 25% increments. If the BYPASS becomes loaded beyond full rating, the fifth (amber) LED indicator will illuminate Bypass Mode Operation at and sound an alarm.

    Ensure the load equipment is turned off, and all loads are properly connected to the UPS output. Check that the mains wall isolator is ON. Turn On (Close) the Battery circuit breaker, Input 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.

    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.
