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. Keep the front and rear vents free of dust accumulation that could restrict airflow. - Page 4 Silence/Manual Battery Test button, a combination Off/Bypass button, and two levels of alarms when the unit is operating on battery. The UPStation GXT has an interface port for communications between the UPS and a LAN server or other computer system.

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 utility power is used as efficiently as possible by the UPS, and the amount of distortion reflected on the utility is reduced. -
Page 6: Static Bypass
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. -

Page 8: Electrical Installation Considerations
The following information is provided for your guidance. On start-up, the UPS will take a half cycle inrush current of up to 3 times the rated current. This must be taken into account when selecting the overload protection device at the input Utility supply distribution point. - Page 9 (protective earth) and grounding electrode conductor (power system earth connection) to reduce electrical noise and provide for safe operation of the UPS and connected loads.

Manual Battery Test Output OFF / Bypass 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. - Page 20 This button controls output power to connected load(s) and has three functions: UPS ON, Alarm Silence, and Manual Battery Test. To start the UPS, while in the BYPASS mode, press the ON button until the command is acknowledged by a beep from the audible alarm.

To increase this time, turn off non-essential pieces of equipment (such as idle computers and monitors) or add optional external battery cabinets. CAUTION: Turning off the UPS while in battery mode will result in loss of output power. Once utility power is restored, the UPS resumes normal operation. At this time, the Battery Charger begins recharging the battery. -
Page 23: Bypass Mode Operation
Output power will be restored automatically upon restoration of utility. When the UPS is standing by in this mode with the utility power absent, all panel LEDs and cooling fans will turn off. - Page 24 Ensure the load equipment is turned off, and all loads are properly connected to the UPS output. Verify that the utility supplying the UPS is turned on by closing any circuit breaker or switch on the supply side of the UPS.
- Page 25 AC LINE LED will be on. To isolate the UPS, turn off the INPUT, OUTPUT, and BATTERY breakers on the rear of the UPS. For complete isolation, turn off the utility to the UPS. ALTERNATE QUICK POWERING DOWN THE UPS The UPS will skip past BYPASS MODE OPERATION directly to OUTPUT OFF MODE OPERATION even with utility available.
- Page 26 MODE OPERATION. All LEDs will turn off and all power to the load will stop. 3. To isolate the UPS, turn off the INPUT, OUTPUT, and BATTERY breakers on the rear of the UPS. For complete isolation, turn off the AC supply to the UPS.
