The UPS warns the user of this LOW BATTERY condition by increasing the acoustic alarm signal
(there is an acoustic signal every second) and by turning on the yellow led of the BAT. LEVEL.
If the AC utility power is not restored within one minute of this condition, the UPS will
automatically switch OFF. This will protect the batteries from a sudden discharge. EVO RT
will stop supplying output power, will deactivate the alarm signals and will place itself in a
stand-by mode. When the AC utility power is restored, the UPS automatically switches ON
and returns to work in LINE mode.
After a complete discharge the UPS will need around 8 hours to completely recharge the
batteries. The recharge is automatic in either two ways:
•
The UPS is ON and running in LINE MODE
•
The UPS is OFF and connected to an AC input line
LOAD TEST
EVO RT indicates the output power percentage through the LOAD LEVEL bar. The output power
is proportional to the number of leds switched on as described in the chapter “External
description”.
The UPS warns of an OVERLOAD condition by lighting up the red OVERLOAD led at the top of
the LOAD LEVEL bar.
In LINE mode, EVO RT has the capability to accept an overload from 110% to 150% for about
30 seconds (the UPS indicated the OVERLOAD condition by lighting up the red OVERLOAD led
and by an acoustic signal every second) and after it switches automatically to the BYPASS
MODE.
In LINE mode, EVO RT automatically switches to BYPASS mode as soon as the overload is
higher than 150%.
Once the requested power is back within range, EVO RT automatically switches to LINE mode
again.
In BATTERY mode, EVO RT has the capability to accept an overload from 110% to 150% for
around 30 seconds (the UPS indicates the OVERLOAD condition by lighting up the red
OVERLOAD led and by an acoustic signal every second) after which it turns OFF automatically.
In BATTERY mode, EVO RT switches automatically off as soon as the overload is higher than
150%.
After removing the cause for the overload condition in order to switch the UPS ON again it is
necessary to press the OFF button. Wait for a few seconds and then press the ON/TEST/ALARM
button.
It is possible to carry out a LOAD TEST in the following way:
•
Make sure that UPS is working in LINE mode, with all powered equipment switched ON and
absorbing MAXIMUM POWER.
•
Press the
ON/TEST/ALARM button
for more than 1 second, to start the TEST.
EVO RT begins operating in BATTERY mode. The TEST is overcome if all equipments keep on
working and if the UPS does not signal any anomalies (overload or other). After a few seconds
the TEST is finished and the UPS returns in LINE mode.
We advise you to carry out the LOAD TEST periodically in order to check the UPS
efficiency.
WARNING
Make sure that the UPS never indicates OVERLOAD when running.
Do not connect a load greater than the rated nominal value on the UPS label (see
POWER specifications in the TECHNICAL CHARACTERISTICS chapter), as this may
damage the unit. In this case the warranty is void.
