MAJOR INTERNAL UPS COMPONENTS
Surge Suppression and EMI/RFI Filters
These components provide surge protection and filter electromagnetic and radio frequency
interference present in the utility line. These components enable the UPS to supply pure
sinewave power to sensitive equipment.
Power Factor Correction Circuit
This circuit changes the utility AC input to DC for use by the inverter and ensures sinewave
input current to the UPS. Sinewave input achieves two things: increased power efficiency
and reduced power distortion.
Inverter
The inverter converts the DC output of the power factor correction circuit to regulated AC
sinewave power. During either normal utility power operation or battery operation, the
inverter continuously generates and regulates output power.
Charger
The charger regulates energy from the power factor correction circuit to continuously
charge the batteries. The charger operates whenever the UPS is ON. For maximum
battery charge life and power protection, leave the UPS ON.
Battery
The sealed, maintenance-free, spill-proof batteries in the UPStation® GX last for 5 years at
typical room temperatures and with normal charging. They maintain UPS output at full
rated power for 10 minutes. Reducing the load increases battery back-up time.
Bypass
This standard UPStation® GX feature provides an alternate power source to the output
automatically in the event of over-temperature or fault within the UPS. Audible and visual
alarms indicate Bypass operation. The UPS remains on Bypass until the user resets the
power switch by turning it OFF then ON.
CAUTION: Resetting the power switch causes loss of power to the outlet receptacles.
Perform all necessary shutdown procedures on critical loads before resetting the power
switch.
BEFORE INSTALLATION
Unpack UPS, carefully noting the packing method. Retain packaging. To return the UPS,
re-pack as originally shipped. CAUTION: The units are heavy. The UGX1000RT-60
weighs 71 Ibs; the UGX1500RT-60 weighs 83 Ibs; the UGX2100RT- 60 weighs 97 lbs.
Take proper precautions when lifting or moving them.
Inspect UPS for freight damage. Contact the carrier and/or your distributor concerning
freight damage or missing parts.
UPS Configuration
Turn UPS On/Off switch OFF. The manufacturer ships the UPStation® GX from the factory
in tower configuration. If this suits your application, follow the tower installation instructions.
If your application requires rackmount configuration, follow the rack-mount installation
instructions.
