TECNOWARE ERA PLUS 800 UNIVERSAL Uninterruptible Power Supply User Manual

TECNOWARE ERA PLUS 800 UNIVERSAL Uninterruptible Power Supply

Introduction

ERA PLUS 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 conditions, ERA PLUS performs output voltage regulation and filters frequently occurring electrical disturbances (such as transients, spikes, interferences, etc.), thus protecting all devices connected to the outlets, and recharging the batteries in an ideal way. In case of an anomaly to the AC line, the UPS continues feeding the protected equipment.
ERA PLUS is equipped with a USB interface that can be used to notify a power failure or a low battery condition directly to a computer: this makes it possible to automatically save your data during an extended black-out with the most widespread operating systems (Windows, Mac OS X, Linux, etc.).

Read this manual carefully before using the ERA PLUS; it includes important safety warnings and useful advice for correct use and installation.
This manual is a guide that enables you to correctly install and use your ERA PLUS. This manual includes important SAFETY instructions for the operator, for the UPS correct installation, and gives useful advice on the product and battery maintenance. For any type of problem, please refer to this manual before calling customer service.

Receipt and site selection

Carefully remove the UPS from its packaging, and carry out a meticulous inspection. We recommend keeping the original packaging in a secure place, in case you need to send the UPS for maintenance purposes. In case of transport damage, notify the carrier and dealer immediately.
We recommend paying attention to the below points in order to choose the correct placement for your UPS:

•  The UPS is designed to operate in a protected environment (e.g. offices). We, therefore, recommend installing it in a place with very little or no humidity, dust or smoke.
• In all circumstances, see the “Technical Characteristics” chapter for environmental specifications and check that the selected area meets these specifications.
• During normal operation, the UPS discharges a minimal amount of heat. So it is necessary to leave at least 20 cm of unobstructed space all around the UPS in order to keep it properly ventilated.
• Do not obstruct ventilation holes.
• Do not insert objects or pour liquids in the ventilation holes.
• Do not rest any object on top of the UPS.
• Do not keep liquids, flammable gases or corrosive substances near the unit.
• Install the UPS on a properly tiled floor. Avoid the installation on a floor that is not tiled flat.

EXTERNAL DESCRIPTION

Front Panel

The front panel informs the user about operating status, alarm conditions, and measurements. The front panel is shown below consists of two parts:

1. The ON/OFF button with LINE/BATTERY led enables the user to turn ON/OFF UPS and indicates with the led (green color) always active the functioning in Normal Mode, it flashes one time every 4 seconds in Battery mode and it flashes one time every second in Low Battery condition.

Rear Side

1. AC Input cable: to connect the UPS to the AC utility line.
2. AC Input Thermal Protection: electrical specification: max current 5 A, voltage 250 V.
3. Grounded UPS Output receptacles: Universal type, black color, to supply critical loads.
4. Computer Interface (USB connector): it is the communication USB port (only for UPS ERA Plus 1.200 and UPS ERA Plus 1.600).

In case of an anomaly to the AC line (black-out), the UPS Output receptacles (black color, #3) continue supplying the correct power to all connected equipment.

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 computers or other electronic devices) that need to be supplied by the UPS.
2. Connect the UPS Input socket to the AC line outlet. It is mandatory to ground the AC line outlet according to the Safety Standards. Carefully check the grounding, and make sure that the utility power is available, and that its range falls within the UPS specifications (refer to the “Specifications” chapter).
3. Press the ON/OFF button on the front panel: the UPS emits a brief acoustic signal, turns the led display on, and performs a functioning SELF-TEST. After some seconds the UPS starts to work in Normal mode. Leave the UPS in Normal mode for at least 4 hours in order to completely recharge the batteries.
4. Switch the UPS off (by pressing again the ON/OFF button).
5. Connect the devices to be supplied to the UPS outputs. Be sure all the devices have the main switch in the ON position. ATTENTION: do not connect on this UPS, Laser printer, Multifunction Printer or similar equipment, because these items have particular power absorbing during their function and the UPS can go in overload.
6. Turn on the UPS again. Check that it starts working correctly and it doesn’t signal any sort of anomaly. Moreover, be sure that all the devices connected to the UPS outputs are working correctly.
7. Simulate a black-out by removing the AC Input line. The UPS starts working in Battery mode: the UPS emits a brief acoustic signal every 10 seconds.
8. Be sure that all the devices connected to the UPS outputs are working correctly and the UPS doesn’t signal any sort of anomaly.
9. Restore the AC Input line: after few seconds the UPS turns back in Normal mode.

Before using ERA PLUS normally, leave it in Normal mode in order to charge the batteries completely as specified at point 3. The batteries reach the 90% of their capacity after about 4 hours of recharge.

It is compulsory to ground/earth the UPS according to the Safety Standards.
Risk of electric shock at the Output lines if the UPS is ON, even when the UPS is not connected to the AC utility line.
Risk of electric shock at the Output lines while the unit is connected to the AC utility line.
Risk of electric shock: do not remove the cover. The UPS contains internal parts, which 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.
Disregarding for these warnings may lead to a risk of electric shock to operators.

Functioning

Normal Mode
The UPS typically works in Normal mode: Input mains power is available and its amplitude is within specifications.
In Normal mode, the LINE/BATTERY button/led is always on.
During Normal mode, the UPS recharges the batteries and keeps them in an optimal charging voltage.

Battery Mode
The UPS automatically runs in Battery mode if the AC Input Line voltage amplitude gets out of security limits (in case of a black-out or over-voltage /low-voltage): in this case, the UPS supplies the required output power by its internal battery and by the Inverter block.
The UPS automatically returns in Normal mode a few seconds after the AC Input Line is recovered.
In Battery mode, the UPS emits an acoustic alarm signal every 10 seconds and simultaneously the LINE/BATTERY button/led flashes.

Low Battery and Automatic Restart
In Battery mode, ERA PLUS indicates the Low Battery condition whenever the battery reaches a charge level allowing connected devices to operate for approximately one more minute. During Low Battery conditions the UPS emits an acoustic alarm signal every second and simultaneously the LINE/BATTERY button/led flashes.
If AC Input does not come back on within a few minutes, the UPS shuts down automatically thus preventing the batteries from discharging excessively; the UPS stops supplying Output power, deactivates the control panel indication, and goes to a waiting state. Once AC Input comes back on, the UPS restarts automatically and after some seconds it goes back to work in Normal mode. After a complete discharge, the UPS needs 4 hours to recharge completely the batteries. The UPS recharges batteries automatically if it works in Normal mode or if it is off and connected to the AC Input Line.

Load Control
When the Output load is higher than the nominal value the UPS warns of the Overload condition by emitting a continuous acoustic alarm.
The UPS warns of an Overload of less than 110% by an acoustic alarm.
An Overload between 110% and 130% are accepted for about 30 seconds and after UPS switches automatically off.
The UPS switches immediately off if the Overload is higher than 130%.
Once the requested power is back within range, the UPS switches automatically to the Normal mode.
Make sure that the UPS never indicates the Overload condition.
Do not connect a load greater than the rated value to the UPS (see POWER specifications in the chapter “Technical Characteristics”), as this may damage the unit. In this case the warranty is void.

Fault Condition
The UPS indicates the Fault condition by emitting a continuous acoustic alarm.
During Fault conditions, the UPS doesn’t supply Output power and so all the supplied devices are switched off.

Communication Interface

The UPS is factory-equipped with USB Communication Interface (only ERA Plus 1.200 and ERA Plus 1.600). On the UPS rear side there is the connector of the USB Interface. The USB signals are all isolated through photo-couplers from the dangerous voltages that are present inside the UPS.
