SYSTEMDESCRIPTION

1.3.1

Modes of Operation

The UPS shall be designed to operate in the following modes:

A. Normal - During normal operation, mains power shall provide energy to the UPS. The filters, the power

factor correction circuit and the inverter shall process the mains to provide computer-grade power to

connected loads. The UPS shall maintain the batteries in a fully charged state.

B. Battery - The UPS shall enter Battery mode if there is an extreme power surge, extreme power sag or mains

failure. The battery system shall supply power through the DC-to-DC converter to the inverter to generate

computer-grade power for the connected load.

C. Recharge - When the UPS is supplied with qualified mains power, the UPS shall charge connected internal

and optional external battery cabinets (if connected).

D. Internal Bypass - Bypass mode shall provide an alternate path for mains power to the connected load in the

unlikely event of a UPS malfunction, such as overload, over temperature or an internal circuit failure.

E. Maintenance Bypass - Maintenance Bypass mode shall provide an alternate path for mains power to the

connected load during UPS maintenance or UPS replacement.

F. Automatic Restart - Upon restoration of mains power and after a complete battery discharge, the UPS shall

be able to automatically restart and resume supplying power to the critical load based on the settings in the

supplied configuration program.

InputConverter

2.2.1.1 General

Incoming mains power shall be converted to regulated DC power by the input converter for supplying DC power

to the inverter. The input converter shall provide input power factor correction (PFC) and input current distortion

reduction.

2.2.1.2 Input Current Limit

The input shall use the power necessary to operate the load attached to the output before going to batteries. The

UPS shall not use electronic input current limiting.

•

The GXT4-10000RT230 shall include a 1-pole, 63Ainput circuit breaker.

2.2.1.3 Input Protection

The UPS shall have built-in protection against over current and overvoltage conditions including low-energy

lightning surges, introduced on the primary input source. The UPS shall sustain input surges without damage per

criteria listed in 61000-4-5 Surges/Lightning.

2.2.1.4 Battery Recharge

The UPS shall contain a three-stage battery charger designed to prolong battery life. The battery shall be constant

current charged to restore capacity, then shall be constant voltage charged to maintain the battery in a fully

charged state. Recharge time for the internal battery shall be 3 hours maximumto 90% capacity (full load

discharge rate). There shall be DC overvoltage protection so that if the DC voltage exceeds the pre-set limit, the

inverter shall shut down automatically and the critical load shall be transferred to internal bypass.

2.2.2

Inverters

2.2.2.1 General

The UPS inverters shall be of a pulse-width-modulated (PWM), IGBT design capable of providing the specified

mains output. The inverters shall convert DC power from the input rectifier output or the battery into precise

sine wave mains power for supporting the critical load.

2.2.2.2 Overload

The inverter shall be capable of supplying current and voltage for overloads exceeding 100%, and 105-130% for

1 minute, 131-150% for 10 seconds, 151 - 200% for 1 second, and up to >200% for 5 cycles of full load current.

A visual indicator and audible alarm shall indicate overload operation. For greater currents or longer time

duration, the inverter shall have electronic current-limiting protection on the output to prevent damage to

components. The inverter shall be self-protecting against any magnitude of connected output overload. Inverter

control logic shall sense and disconnect the inverter from the critical AC load without the requirement to clear

protective devices.

2.2.2.3 Inverter DC Protection

The inverter shall be protected by the following DC shutdown levels:

•

DC Overvoltage Shutdown

•

DC Under voltage Shutdown (End of Discharge)

2.2.2.4 Output Frequency

An oscillator shall control the output frequency of the UPS. The inverter shall maintain the output frequency to

±0.1Hz of nominal frequency during Battery mode, Frequency Converter mode or when otherwise not

synchronized to the mains source.

SLI-23197_Rev 1 8Guide Specifications

Liebert GXT4-10000RT230

2.2.2.5 Output Protection

The UPS inverter shall employ electronic current limiting circuitry for protection during Normal mode and

battery operation and the UPS shall employ input circuit breaker protection during Bypass mode operation.

2.2.3

Display and Controls

2.2.3.1 General

The UPS shall be provided with a microprocessor-based control and a status display section designed for

convenient and reliable user operation. The monitoring functions such as status and alarm indicators shall be

displayed on a front-panel LED display.

2.2.3.2 UPS Status Indicators

The GXT4-10000RT230 shall include five individual LCD status indicators and three rows of LCDs to indicate

UPS load and battery capacity. An audible alarm shall be used in conjunction with the visual indicators to

indicate to the operator a change in UPS operating status.

All audible alarms can be silenced, with the exception of low battery, bypass reminder and missing batteries at

startup alarms. Once silenced, the audible alarm shall not sound until a new alarm condition is present. Standard

LCD indicators are described below:

The five LED indicators on the front of the operation and display panel are:

1. Inverter , 2. Battery , 3. Bypass , 4. ECO Mode, 5. Fault

2.2.3.4 ON-LINE BATTERY TEST

The UPS shall feature an automatic battery test with the factory default test interval set at every 8 weeks. The

battery test shall ensure the capability of the battery to supply power to the inverter while loaded. If the battery

fails the test, the UPS shall display a warning alarm to indicate the internal batteries need replaced and resume

operation without disturbing the load. The battery test feature shall be user accessible by the push button on the

front of the unit.

General

SLI-23197_Rev 1 9Guide Specifications

Liebert GXT4-10000RT230

A maintenance bypass circuit shall be provided as an integral part of the UPS. The maintenance bypass shall have

a break-before-make transfer, shall have a maximum detect and transfer time of 4-6 milliseconds and shall be a

double-pole device. The maintenance bypass shall be configured to wrap around the PFC converter, battery

charger, DC-DC converter, inverter and battery. The maintenance bypass circuit shall use the rear-panel mounted

UPS mains circuit breaker and route bypass power through the UPS input filters and surge suppression circuit.

The maintenance bypass circuit default position shall be in the Bypass mode (mains).

2.3.2

AutomaticTransfers

The transfer control logic shall activate the bypass automatically, transferring the critical mains load to the bypass

source, after the transfer logic senses one of the following conditions:

•

UPS overload

•

UPS over temperature

•

PFC failure

•

Inverter failure

•

DC bus overvoltage

Once the overload condition is reduced, the load shall be automatically transferred back to inverter power. An

over temperature requires manual transfer back to inverter power after cooling.

2.4

INTERNALBATTERY

Valve-regulated, non-spill able, lead acid cells shall be used as a stored-energy source for the specified UPS

system. The battery kit shall be internal to the UPS cabinet and sized to support the inverter at rated load and

power factor with an ambient temperature of 25°C (77°F) for a minimum of 3 minutes reserve time. The expected

life of the battery shall be 3-5 years or a minimum250 complete discharge cycles at ambient temperature of 25°C

(77°F). To promote battery service life and eliminate over-discharge of the battery, the end-of-discharge DC

shutdown voltage shall be automatically adjusted by the microprocessor based upon the percentage load at the

onset of battery operation.

2.5

OUTPUTDISTRIBUTION

Output distribution shall be integral to the UPS cabinet and located on the rear of the unit. The integrated

distribution panels that come standard on the UPS are listed below:
