Liebert GXT3 5000RT208 - 1.3.2 Design Requirements

Liebert GXT3-5000/6000RT208
SL-23188_REV1_08-10 3 Guide Specifications
1.3.2 Design Requirements
A. Voltage: Shall operate at either 120/208V or 120/240V by sensing the utility phase angle and configuring the
dual inverters to the same angle: 120 or 240 degrees (or) 180 degrees. Nominal input/output voltage
specifications of the UPS at rated load shall be:
Input
The UPS shall automatically configure itself to operate from 120/208V, 50/60Hz (or) 120/ 240V, 50/60Hz
without the use of selector switches or voltage taps. Input wiring must be 3-wire plus ground (L1, L2, N, G,
with N solid bonded to G at the distribution panel).
Output
Output voltage shall be present at terminals L1, L2 and N. The output voltage shall be automatically set to
match input voltage of 120/208V, 50/60Hz (or) 120/240V, 50/60Hz. Voltage measured between L1-N and L2-
N: 120VAC ±3%, 50/60Hz; L1-L2: 208 or 240VAC (auto-sensing to match input phase angle) ±5%, 50/60Hz.
The UPS shall be configurable using the included configuration program to provide the following alternate
voltages:
127/220V, 115/230V, 110/220V, 100/200V, all voltages ±3% at 50 or 60Hz.
(If the UPS is started on battery with no input power present, the default output voltage shall be 120/208V,
60Hz from the factory. After the UPS has been started from utility, the output voltage/frequency shall match
the last known input voltage/frequency that was applied.)
B. Output Load Capacity: Specified output load capacity of the UPS shall be:

C. Internal Battery: Valve-regulated, non-spillable, lead acid cells.
D. Battery Reserve Time: Minimum 4 minutes with an ambient temperature of 77°F (25°C).
E. Battery Recharge: The UPS shall contain a battery recharge rate designed to prolong battery life. Recharge
time for UPS internal batteries shall be 3 hours maximum to 90% capacity after a complete discharge into
full load.
