1.3.	SYSTEM DESCRIPTION
1.3.1	Modes of Operation
The UPS is designed to operate as an off-line (standby) 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.
B.  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.
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 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.

2.2	COMPONENTS and operation
2.2.1	Input Protection
The UPS has built-in protection against undervoltage, overcurrent, and overvoltage conditions including low-energy lightning surges introduced on the primary input power source. The UPS is provided with an input circuit protector. The 120 VAC UPS models withstand input surges without damage per criteria listed in IEEE C62.41, Category A, Level 3.  Additionally, the UPS is supplied with one pair of Data Line Protection Connectors to provide phone, fax or modem line surge protection via RJ-45 connectors.  These Data Line Protection Connectors support transmission of 10/100 Base-T Ethernet connection.

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.
2.2.3	Inverter 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)
2.2.4	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.
2.2.5	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 a 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.
2.2.6	Output Frequency
An oscillator controls the output frequency of the UPS.  The oscillator maintains the output frequency to ±0.1 Hz of nominal when not synchronized to the utility/mains source.
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.

2.3	Display and Controls
2.2.3.1	General
The UPS is provided with a microcontroller-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.
The Battery Indicator illuminates to indicate the UPS is operating on battery (green) or (Flashing - amber) to signify a battery warning (Low Battery or Replace Battery).
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 to be 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 o F (25 o C) for a minimum of 4 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 can also be shut off regardless of what mode the UPS is operating in by shorting Pin 5 and Pin 6.  The UPS communicates via serial communications using Liebert ESP II protocol. The pin out configuration of the DB9 connector is:

Pin	Assignment Description	
1	Low Battery (open collector)	
2	UPS TxD (typical RS-232 levels)	
3	UPS RxD (typical RS-232 levels)	
4	Remote Shutdown (5-12V); on Battery mode	
5	Common	
6	Remote Shutdown (short to pin 5); any mode	
7	Low Battery (open emitter)	
8	AC Fail (open emitter)	
9	AC Fail (open collector)	
Maximum voltage and current on Pins 1, 7, 8, and 9 is 55VDC; 10.0 mA.

The PowerSure PSP 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 manage 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.
