IMPORTANT SAFETY INSTRUCTIONS 1. SAVE THESE INSTRUCTIONS. THIS MANUAL CONTAINS IMPORTANT SAFETY INSTRUCTIONS. Read all safety and operating instructions before operating the Uninterruptible Power System (UPS). Adhere to all warnings on the unit and in this manual.
1 10. Storing magnetic media on top of the UPS may result in data loss or corruption. 11. Turn the UPS off and isolate the UPS before cleaning. Use only a soft cloth, never liquid or aerosol cleaners.
2 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.
3 RECTIFIER/POWER FACTOR CORRECTION (PFC) CIRCUIT In normal operation, the rectifier/power factor correction (P FC) 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.
4 CONTROLS AND INDICATORS Fault Indicator (Red) The Fault indicator is illuminated if the UPS has detected a problem. Also, one or more of the load/battery level indicators may be illuminated (refer to Troubleshooting Guide). BYPASS Indicator (Amber) The BYPASS indicator is illuminated when the UPS is operating from BYPASS power.
5 The UPStation GXT is equipped with au tomatic 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).

7 OPERATING MODES NORMAL MODE OPERATION - UPS mode During normal operation, mains power provides energy to the UPS. The filters, the power factor correct ion circuit and the inverter process this power to provide computer grade power to connected loads.
8 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 illumi nate and sound an alarm.
9 STARTING THE UPS 1. Ensure the load equipment is t urned 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.
10 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.
11 TROUBLESHOOTING The information below indicates various symptoms a user may encounter in the event the UPStation GXT develops a problem. Use this infor mation to determine whether external factors cause the problem and how to remedy the situation. 1.
12 AUDIBLE ALARM CONDITIONS CONDITION ALARM Battery mode (utility failure) One short beep every ten seconds Low battery Two short bee ps every five seconds Output overload (bypass) One short beep ever.
13 TROUBLESHOOTING GUIDE PROBLEM CAUSE SOLUTION Fault and Bypass indicators and all load level LED's are illuminated UPS overl oaded or load equipment is faulty Check load level display and remove non - essential loads. Recalculate load VA and reduce number of loads connected to UPS.
14 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.
15 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.
16 INSTALLATION INSTRUCTIONS These instructions are for use by competent personnel only. INSTALLATION CONSIDERATIONS Detailed instructions to help you install the UPS are provided in the following pa ges; however, you should give some consideration to the proposed environment in which the UPS is to be installed, and carry out some preparatory work.

18 ELECTRICAL CONNECTIONS T he UPS is supplied with an input/output/ battery terminal block assembly on the rear of the UPS within a cable box. (see outline drawing) The cable box can be removed to enable knockouts to be removed or new holes drilled, to secure the cables .
19 Connecting the UPS Power cables Power cables connect to screw terminals on a terminal block that is located behind the rear mounted cable box (see figure). The cables enter the UPS through a Gland Plate attached to the rear of the UPS. The Gland Plate must first be removed and drilled to suit the glands or bushes for the cables used.
20 Stabilisers/Levelling Feet When the UPS is located in its final position before or after wiring, it is necessary to fit stabiliser brackets and, if necessary, adjust the levelling feet. If the UPS is wired using a rigid wiring system, then movement of the UPS must be prevented by winding down the 4 levelling feet under the UPS as shown below.
21 COMMUNICATIONS INTERFACE PORT The UPStation GXT UPS contains a standard DB - 9 socket loca ted on the rear of the UPS unit. Several signals are provided on this port and are assigned as follows: PI.
22 FERRITE BEAD INSTALLATION When using either of the options below, to reduce the risk of radio interference, fit the ferrite assemblies supplied with the UPS as follows: Serial Communications Attach.
23 COMMISSIONING THE UPS Output Voltage Selector Switches The Output Voltage Selector Switches, lo cated on the rear of the UPS, are designed to allow selecting or changing the desired output voltage to match the mains. The settings to choose from are 208, 220, 230, and 240 VAC output.
