9. FUNCTIONING
TURNING ON AND OFF
UPS EVO TM is equipped with a
main switch placed on the rear
(see figure 4). If this switch
is in OFF position than UPS is completely OFF; else UPS is ON in one of the three functioning
modes (LINE mode, BATTERY mode, BYPASS mode).
If UPS is used daily is recommended to leave the main switch always ON and turn ON/OFF the
UPS by the
ON
and
OFF
buttons on the frontal panel to activate/de-activate the INVERTER.
If UPS EVO TM has to be turn OFF for several days is recommended to turn OFF the main
switch.
Let’s see carefully the consequences of the pressure of buttons
ON
and
OFF
.
The UPS is in BYPASS MODE
(INVERTER is OFF)
;
if the
ON
button is pressed, after few seconds
the INVERTER starts and after 20 seconds UPS switches in LINE mode.
If the
ON
button is pressed when AC utility line is not present, UPS EVO TM switches on even,
and works in BATTERY mode after about 20 seconds.
If UPS is ON, press
OFF
button continuously for approximately 3 seconds to deactivate
INVERTER: if AC utility line is present, then the UPS switches from LINE mode to BYPASS
mode, but if the UPS is functioning in BATTERY mode, then the INVERTER switches off and
consequently there will be no output power.
WARNING
As showed before, in BYPASS mode, the INVERTER is de-activated and UPS EVO TM
doesn’t work as a UPS, but only as a bypass between input and output of the mains.
In BYPASS mode, the UPS supplies the load only if AC utility line is restored. The load
in BYPASS mode isn’t protected in case of black-out.
LOW BATTERY AND AUTOMATIC RESTART
UPS EVO TM reaches
LOW
BATTERY
condition
(
BATTERY LOW
) whenever, during functioning
in BATTERY mode, the battery reaches a charge level allowing connected devices to operate for
approximately 1,5 more minutes.
UPS EVO TM warns operators of LOW BATTERY lighting the BATTERY LOW led, by emitting an
acoustic signal every second, and on LCD display is visualized the message:
“
AC: LOSS BAT: LOW
”.
If AC utility power does not come back on within a minute, the UPS
shuts down
automatically
thus preventing the battery from discharging excessively; EVO TM stops
supplying output power, deactivates control panel indication and goes to a waiting state. Once
AC utility power comes back on, it
restarts automatically
like is pressed
ON
button in frontal
panel and after 20 seconds backs to work in LINE mode.
After a complete discharge, the UPS needs 10 hours to recharge completely the batteries. UPS
recharges batteries automatically if it works in LINE mode or in BYPASS mode.
