UPS EVO DSP MM Rack Tower
It is compulsory to ground the UPS according to the Safety Standards.
The case of the UPS is internally connected to the ground terminal (GND) of the IN/OUT
terminals, in order to guarantee safety to the user. To guarantee safety it is necessary
to be sure that the local electric plant is supplied with GROUND (in compliance with the
Safety Standards), and that a valid connection is guaranteed between the GROUND of
the UPS and the GROUND of the local electric plant.
Any interruption of the GROUND conductor is absolutely prohibited.
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 which 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.
Disregard for these warnings may lead to a risk of electric shock to operators.

First Start Up
Turning the UPS ON is very easy. Nevertheless we recommend that, on First Start Up, the following procedure is
observed for greater safety.
1.
Be sure all the devices connected to the UPS outputs have the main switch in OFF position.
2.
Restore the AC Input line for the UPS; be sure that the AC utility power is available, and that its voltage and
frequency are within the specifications.
3.
As a consequence of point 2, the UPS turns on the graphic display and goes in
Stand-by mode
: the UPS
recharges only the batteries and doesn’t supply Output power. Check the graphic display shows the
functioning of the battery charger during Stand-by mode.
4.
Press
ON/MUTE
button for at least 3 seconds: the UPS emits a brief acoustic signal and performs a
functioning SELF-TEST
. After some seconds the UPS starts to work in
Normal Mode
and the graphic LCD
panel will show the functioning during Normal mode.
5.
Simulate a black-out by removing the AC Input line. The UPS starts working in
Battery mode
: the graphic LCD
panel will show the functioning during Battery mode. Moreover UPS emits a brief acoustic signal every 4
seconds. When Battery level is ending the acoustic signal will be emitted every 1 second.
6.
Restore the AC Input line: after few seconds the UPS turns back in
Normal mode
.
7.
The UPS has passed first start up check: now turn ON the devices (one by one) to be supplied by UPS,
checking the UPS doesn’t report
Overload
information on the graphic LCD panel and all the devices are
working regularly. By graphic display check if the Output load percentage is less than 100%; otherwise it is
necessary to remove part of the loads at the Output lines.
Before using the UPS normally, leave it in Normal mode for in order to charge Battery completely (the UPS charges
Battery also in Bypass mode or in Stand-by Mode). The batteries reach the 90% of their capacity after about 4
hours of recharge.
