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 Through the Personal Computer supplying cable. It is mandatory to ground the AC line outlet according to the Safety Standards. Carefully check the grounding, 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 LCD display on, and performs a functioning SELF-TEST. After some seconds the UPS starts to work in Normal mode: the AC MODE icon is on. 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, by using only the included cables. Be sure all the devices have the main switch in ON position.
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. By LCD display check if the Output load percentage is less than 100%; otherwise, it is necessary to remove part of the Output load.
7. Simulate a black-out by removing the AC Input line. The UPS starts working in Battery mode: the AC MODE icon is off and the BATTERY MODE icon is on. Moreover, 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 EXA 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 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.
• 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.

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.
• The Battery mode is identified by the lighting of the BATTERY MODE icon and by an acoustic signal every 10 seconds.

Low Battery and Automatic Restart

• In Battery mode, EXA PLUS indicates the Low Battery condition whenever the battery reaches a charge level allowing connected devices to operate for approximately one more minute.
• The UPS warns operators of Low Battery by lighting of the LOW BATTERY icon on the LCD display and by emitting an acoustic signal every second.
• If AC Input does not come back on within few minutes, the UPS shuts down automatically thus preventing the batteries from discharging excessively; the UPS stops supplying Output power, deactivates 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

• The UPS indicates the Output Load level by LCD display (on the right side as described in chapter 4).
• When the Output load is higher than nominal value the UPS warns of Overload condition by LCD display, by lighting of the OVERLOAD 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.
• The UPS switches immediately off if the Overload is higher than than 130%.
• Once the requested power is back within range, the UPS switches automatically to Normal mode.

Make sure that the UPS never indicates Overload condition.
Do not connect a load greater than 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 LCD display, by lighting of the ERROR icon and by emitting a continuous acoustic alarm.
• During Fault condition, the UPS doesn’t supply Output power and so all the supplied devices are switched off.

Communication Interfaces

• The UPS is factory-equipped with USB Communication Interfaces. On the UPS rear side there is the connector of the Interface.
• The USB signals are all isolated through photo-couplers from the dangerous voltages that are present inside the UPS.
• Connecting to the Web site www.tecnoware.com, it is possible to download, free of charge, the update UPS management Software TECNOMANAGER, compatible with the most popular Operative Systems.

Technical Characteristics

• Connect the printers to the ONLY FILTERED Output sockets
