Safety Warnings Read this manual carefully and completely before installing and using the TECNOWARE ERA LCD 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 ERA LCD is a Line Interactive 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, micro-interruptions), which often cause damage to your Hardware and Software. Under normal AC line condition, ERA LCD performs output voltage regulation and filters frequently occurring electrical disturbances (such as transients, spikes, interferences, etc.
2 General Characteristics ERA LCD 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.
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 and Output Voltage, 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 ERA LCD 0.65 – 0.85 – 1.
4.1.1 LCD Display Please refer to figure 2. 1 2 3 4 7 6 5 8 9 Figure 2 –LCD Display 1. INPUT: the 3 digits indicate the Input Voltage. 2. OUTPUT: the 3 digits indicate the Output Voltage. 3. BATTERY LEVEL: is a four-segment light bar. This bar indicates the battery charging percentage as explained below: 4. • 0~25%: only 1 segment is on. • 25~50%: 2 segments are on. • 50~75%: 3 segments are on. • 75~100%: all the 4 segments are on. LOAD LEVEL: is a four-segment light bar.
4.2 Rear Side 6 5 3 3 4 1 2 Figure 2 – Rear Side 1. Grounded AC Input power socket: IEC C14 type; to connect the UPS to the AC utility line. 2. Input fuse: electrical specification: max current 5 A, voltage 250 V. 3. Grounded UPS Output receptacles: IEC C13 type, black colour, to supply critical loads. 4. Grounded (ONLY FILTERED) Output receptacles: IEC C13 type, red colour, to supply NON-critical loads. 5.
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. The Normal mode is identified by the lighting of AC MODE icon. 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 (on the right side 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 lighting of the OVER LOAD icon and 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.
8 Technical Characteristics UPS ERA LCD Model Power Recommended for: 0.65 0.85 1.
9 Maintenance 9.1 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.
Battery replacement must be performed exclusively by qualified technical personnel authorized by TECNOWARE. TECNOWARE declines any responsibility if this warning is disregarded. When replacing batteries, replace with the same type and number. CAUTION: A battery can present a risk of electrical shock and high short circuit current.
Risk of electric shock: do not remove the cover. The UPS contains internal parts that are at a high Voltage and are potentially dangerous, capable of causing injury or death by electric shock. There are no internal parts in the UPS that are user serviceable. Any repair or maintenance work must be performed exclusively by qualified technical personnel authorized by TECNOWARE. TECNOWARE declines any responsibility if this warning is disregarded.
Conformity to the European Directives TECNOWARE S.r.l. confirms that ERA LCD 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.
