BATTERY
The UPStation GXT™ employs valve regulated, nonspillable, lead acid batteries.
At typical room temperatures and with the UPS float charging, the battery system
will last many years. Optional external battery cabinets are available to provide
extended run times. For battery run times, refer to the Typical Battery Discharge
Curves.
DYNAMIC 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. Bypass operation is
indicated by an alarm and an illuminated Bypass LED (other LED’s may be
illuminated to indicate the diagnosed problem). To manually transfer the
connected load from the inverter to bypass power, press the Off button once.
NOTE: The bypass power path does NOT protect the connected equipment
from disturbances on the utility supply.
GENERAL INSTALLATION
TOWER UPS INSTALLATIONS
1. Unpack the UPS carefully noting the packing method. Retain the box and
packing material for possible future shipment.
2. CAUTION: The UPS is heavy (see specifications). Take proper precautions
when lifting or moving it.
3. Visually inspect the UPS for freight damage. Report damage to the carrier
and your dealer.
4. Ensuring load equipment is turned off, plug all loads into the UPS output
receptacles.
5. Plug the UPS into a dedicated wall receptacle properly protected by a circuit
breaker or fuse in accordance with the National And Local Codes. Use a 15
amp rated device for the 1800 VA units, and a 20 amp device for the 2700
VA unit. The wall receptacle must be grounded.
6. Locate the UPS indoors in a controlled environment, where it cannot be
accidentally disconnected. Locate it in an area with unrestricted air flow,
away from water, flammable liquids, gases, corrosives, or conductive
contaminants. Maintain a minimum of 4 inches (100 mm) clearance in front
and rear of the UPS. Maintain an ambient temperature range of 32° to 104°
NOTE: UPS operation in temperatures above 77° F (25° C) reduces battery
life.
7. Turn on the UPS by pressing the On button for at least one half second; then
turn on the connected load equipment. The UPS is ready for normal
operation.
