1.3. SYSTEM DESCRIPTION

1.3.1 Modes of Operation

The UPS is designed to operate as a line-interactive system in the following modes:

A. Normal - The critical AC load is continuously supplied with filtered power. The battery

charger maintains a float-charge on the battery.

PowerSure PSA Guide Specification

350 – 1000VA SL-23271 8/03

B. Voltage Boost/Buck - During input power source abnormalities (sags and swells), the AC

output power is corrected by means of boost (sag correction) or buck (swell correction)

compensation taps. Operation of the compensation taps automatically maintains the proper

output voltage for the connected critical equipment. The compensation taps is designed for

indefinite operation to their limits. Operation of the compensation taps will not discharge the

battery.

C. Recharge - Upon restoration of utility / mains AC power, after a utility / mains AC power

outage and complete or partial battery discharge, the unit automatically restarts and resumes

supplying power to the critical AC load; and the battery charger recharges the battery.

D. Battery - When the input power source exceeds the parameters defined in section 1.3.3.1, the

critical AC load is supplied power by the inverter, which obtains its power from the battery.

Typical detection and transfer time is 4-6 ms.

E. Battery Start- The UPS is capable of starting without input power. The unit starts up and

operates from the battery, with output frequency the same as the last operating frequency.

350 – 1000VA SL-23271 8/03

2.2.2 Bi-Directional Converter

2.2.2.1 General

The Bi-Directional Converter incorporates solid-state devices and control circuitry to

convert AC power to regulated DC power for battery charging; and convert DC power

from the battery to regulated and conditioned stepped-sinewave AC power for supporting

the critical load. The Bi-Directional Converter is a pulse width modulated (PWM)

design. The Bi-Directional Converter operates in the following modes:

1. In Normal mode of operation, the Bi-Directional Converter maintains the

battery system at a float charge.

2. In Battery mode of operation, the Bi-Directional Converter converts DC power

from the battery to regulated and conditioned stepped-sinewave AC power for

supporting the critical load.

3. In the recharge mode of operation, the Bi-Directional Converter converts AC

power to regulated DC power to recharge the battery.

2.2.2.2 Battery Recharge

The UPS contains a battery recharge rate designed to prolong battery life. The battery is

constant voltage charged to recharge and maintain the battery in a fully charged state.

Recharge time is 6 hours maximum to 90% rated capacity after discharge into full

resistive load.

2.2.2.3 Bi-Directional Converter DC Protection

The following DC shutdown levels protect the UPS:

DC Overvoltage Shutdown

DC Undervoltage Shutdown (End of Discharge)

DC Undervoltage Warning (Low Battery Reserve)

2.2.2.4 Output Protection

For output faults including short circuits and overloads, the UPS is protected by the input

circuit protector during Normal mode and by electronic current limiting during Battery

mode.

2.2.2.5 Overload

The UPS is capable of supplying power for overloads exceeding 100% and up to 110%

of full load rating, continuously. A visual indicator and audible alarm indicate overload

operation. For greater current demands, the UPS employs circuit protector and electronic

current-limiting protection to prevent damage to components. The UPS is self-protecting

against any magnitude of connected output overload. The UPS control logic senses and

disconnects the UPS from the critical AC load and clears the protective circuit breaker

during Normal mode.

2.2.2.6 Output Frequency

An oscillator controls the output frequency of the UPS. The oscillator maintains the

output frequency to + 0.5 Hz of nominal when not synchronized to the utility/mains

source.

2.2.2.7 Battery Over-Discharge Protection

To prevent battery damage due to excessive discharge levels, the UPS control logic

automatically monitors the battery voltage and load level and switches off the output at

the predetermined battery shutdown voltage set point.

350 – 1000VA SL-23271 8/03

2.2.3 Display and Controls

2.2.3.1 General

The UPS is provided with a microprocessor-based unit status and control display

designed for convenient and reliable user operation. The status and alarm indicators are

displayed on a status indicator display.

2.2.3.2 System Indicators

There are three (3) status indicators on the front of the UPS (Utility, Battery and Fault)

and one (1) on the rear (Site Wiring Fault):

The Utility Indicator illuminates when the UPS is operating and supplying

power to connected loads: green indicates Normal mode, amber denotes

Buck/Boost mode.

The Battery Indicator illuminates to indicate the UPS is operating on battery

(green) or to signify a battery warning (amber).

The Fault Indicator illuminates when the UPS detects a problem: red for an

internal UPS fault, green for overload and over-temperature conditions.

The Site Wiring Fault Indicator on the rear panel illuminates red when the UPS

detects a line-neutral reversal or a poor neutral-ground bond.

2.2.3.3 On/Off Controls

UPS start-up and shutdown operations are accomplished by the "On/Off/Alarm Silence"

push button located on the front panel of the UPS. Depressing the button for more than

0.5 sec will start-up the UPS and to turn the UPS off the button will need to be depressed

for more than 2 sec

2.2.3.4 On-Line Battery Test

The UPS is provided with an automatic biweekly battery test feature. The test ensures

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

fails the test, the UPS will display a warning to indicate the batteries need replaced. The

battery test feature is user accessible via Multilink.

2.2.4 Internal Battery

Valve regulated, non-spillable, lead-acid cells are used as a stored-energy source for the specified

UPS system. The battery is housed internal to the UPS cabinet, and sized to support the inverter at

rated load and power factor, with ambient temperature of 77 oF (25 oC) for a minimum of 5

minutes reserve time. The expected life of the battery is 3 - 5 years or 250 complete discharge

cycles.

2.2.5 Output Distribution

Output distribution is integral to the UPS and is located on the rear of the unit.

2.2.6 Communications

The UPS has a DB-9 (9 pin female) connector on the rear to allow UPS status communications

with a computer system running MultiLink™ software. The DB-9 is capable of supplying serial

communication, on battery and low battery signals. MultiLink, Liebert’s UPS monitoring and

shutdown software, is shipped with the UPS, along with a 10-ft. (3m) DB-9 cable required for

running MultiLink.

The UPS can signal “on battery” and “low battery” using opto-couplers. When the UPS is

operating in Battery mode, it can receive a signal from the host computer system that will shut

down the UPS (after gracefully shutting down the operating system on the host computer system)

when the remaining battery run time is low. The timing of the signal depends on MultiLink’s

configuration settings. This shutdown signal (5-12VDC) must have a duration of at least 1.5

seconds for the UPS to be shut down. The UPS communicates via serial communications using

Liebert ESP II protocol.

The PowerSure PSA has a USB interface port for communication that will work with the built-in

Microsoft Power Manager software on the user’s PC, if the PC is so equipped. It will provide UPS

status and manages the automatic orderly shutdown of the computer. The UPS (USB)

communications meets HID standard, version 1.11. All USB models are compatible with

Microsoft Windows 2000, Windows XP and Mac OS 10.2 or later. All USB models ship with a 6-

ft. (1.8m) USB cable.

The pin out configuration of the DB9 connector is:
