Safety Warnings Read this manual carefully and completely before installing and using the TECNOWARE EXA Uninterruptible Power Supply, which, from here after, will also be referred to as UPS. This manual should be kept close to the UPS and read before the UPS is installed and used. The UPS must be used only by properly trained personnel.
1 Introduction EXA is a Line Interactive Pure Sinewave UPS (Uninterruptible Power Supply) specifically designed to protect your computer from any type of irregularities in the AC line (such as black-outs, under or over voltages, microinterruptions), which often cause damage to your Hardware and Software. Under normal AC line condition, EXA performs output voltage regulation and filters frequently occurring electrical disturbances (such as transients, spikes, interferences, etc.
2 General Characteristics EXA has all the advanced features, which guarantee maximum reliability and safety: • All functions are controlled by a microprocessor, giving full guarantee of high reliability. • Output Voltage regulation through AVR (Automatic Voltage Regulation). • Overload protection both in normal mode and in battery mode. • High performance battery charger, which extends the battery medium life ensuring an optimal recharge. • Start up even if the electrical network is not available.
4 EXTERNAL DESCRIPTION 4.1 Front Panel The front panel informs the user about operating status, alarm conditions and measurements. Front panel shown below consists of two parts: 1. LCD display provides information about input (only in line mode) and output voltage, output frequency (only in battery mode), battery level percentage, load level percentage, functioning modes, alarm and fault conditions. 2. ON/OFF button: enables the user to turn ON/OFF the UPS. 1 2 Figure 1 – Front panel UPS EXA 1.1-1.

Input fuse: electrical specification: max current 6A (EXA 1.1–1.5), max current 8A (EXA 2.2) or max current 10A (EXA 2.6-3.2), voltage 250 V. 3. Grounded UPS Output receptacles: IEC C13 type, black colour, to supply critical loads. 4. Grounded ONLY FILTERED Output receptacles (only for EXA 1.1-1.5-2.
5 Electrical Installation and First Start Up We advise you to follow the steps below explained for greater safety: 1. Switch off all the devices (Personal Computer or other electronic devices) that need to be supplied by the UPS. 2. Connect the UPS Input socket to the AC line outlet Through the Personal Computer supplying cable. It is mandatory to ground the AC line outlet according to the Safety Standards.
6 Functioning 6.1 Normal Mode The UPS typically works in Normal mode: Input mains power is available and its amplitude is within specifications. During Normal mode, the UPS recharges the batteries and keeps them in an optimal charging voltage. 6.
6.4 Load Control The UPS indicates the Output Load level by LCD display (as described in the chapter 4). When the Output load is higher than nominal value the UPS warns of Overload condition by LCD display, by emitting a continuous acoustic alarm. The UPS warns of an Overload less than 110% by acoustic alarm. An Overload between 110% and 130% is accepted for about 30 seconds and after UPS switches automatically off. The UPS switches immediately off if the Overload is higher than than 130%.

9 9.1 Maintenance UPS Cleaning Before starting any cleaning operation, be sure that: 1. The AC Input Voltage for the UPS has been removed. 2. The UPS is OFF. Use only a cloth dampened with water to clean the unit. If UPS works in an environmental unusually dusty or dirty, remove the dirty from the ventilation holes. Before restarting the UPS be sure it is completely dry. If any liquid gets inside the UPS, do not start the unit and contact Technical Service immediately. 9.
10 Troubleshooting Alarms and problems you may encounter during operating the UPS are given in the table below. Apply the suggestions corresponding to each anomaly as described into the table. If your anomaly is excluded or the suggested actions do not solve your problem, consult the Technical Service. Please give the following information to the Technical Service: Model and serial number of the UPS, which can be found on the nameplate on the rear of the UPS. Description of anomaly.
Conformity to the European Directives TECNOWARE S.r.l. confirms that EXA models comply with the requirements set out in: the Low Voltage Directive (Safety) 2006/95/EC and following amendments, the EMC (Electro-Magnetic Compatibility) Directive 2004/108/EC and following amendments.
