4 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 t o voltage sags, spikes, or complete power[...]

5 MAJOR COMPONENTS 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. RECTIFIER/POWER FACTOR CORRECTION (PFC) CIRCUIT In normal opera[...]

6 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 fai lure condition, the UPS automatically transfers the connected load to BYPASS providing the bypass voltage is within specification. BYPASS oper[...]

16 STABILIZERS / LEVELING FEET When the UPS is located in its final position before or after wiring, it is necessary to fit stabilizer brackets and, if necessary, adjust the leveling fe et. If the UPS is wired using a rigid wiring system, then movement of the UPS must be prevented by winding down the 4 leveling feet under the UPS as shown below. Fo[...]

17 FERRITE BEAD INSTALLATION When using either of the options below, to reduce th e risk of radio interference, fit the ferrite assemblies supplied with the UPS as follows: Serial Communications Attach the smaller enclosed ferrite bead clamp to the communication cable as shown in the drawing using the following directions: • Open the fe rrite bea[...]

18 COMMISSIONING THE UPS Output Voltage Selector Switches The Output Voltage Selector Switches, located on the rear of the UPS, are designed to allow selecting or changing the desired output voltage to mat ch the utility. The settings to choose from are 208, 220, 230 and 240 VAC output. NOTE: NEVER change the switch settings while UPS is on and pow[...]

19 CO NTROLS 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).
