User’s manual
OUTPUT1 is a NON PROGRAMMABLE Output: please connect all the critical devices to
OUTPUT1.
Instead OUTPUT2 is a PROGRAMMABLE Output: please connect ONLY the non-critical
devices to OUTPUT2.
During power failure, you may extend the backup time to critical devices by setting
shorter backup time for non-critical devices.
As default OUTPUT2 is NOT programmed.
In the case you need to program OUTPUT2 please consult Tecnoware Service for the instruction.

EPO (Emergency Power Off)
EVO DSP PLUS TM models have the EPO (Emergency Power OFF) connector on the rear side, (see figure 6).
This permits to immediately switch the UPS Output OFF from a distance in case of emergency.
The UPS is supplied with EPO short-circuited terminals and in this case the product works normally.
If you want to use an external switch to turn OFF the UPS by EPO, then remove the short-circuit from the EPO
terminals and connect the switch to the EPO terminals as described in the figure 6.

Figure 6 – EPO (Emergency Power OFF)
If the switch is CLOSED the UPS works normally; if, on the contrary, the switch becomes
OPEN then the UPS Output turns OFF immediately.
To switch the UPS Output ON again after an EPO, it is necessary to close again the EPO switch.
The EPO terminals are isolated and do not need an external feeding Voltage.

Electrical Installation
The electrical installation has to be done by qualified personnel. Follow all the Safety
Standards (CEI Standards in Italy or IEEE elsewhere) for the Input/Output connections
and for the right selection of Input/Output cables.
We recommend to use dedicate AC Input/Output power lines for the UPS.
For safety we recommend using external circuit breakers between Input mains and UPS
AC Input line and between UPS Output lines and the loads. The circuit breakers should
be qualified with leakage current protective function (leakage current < 30 mA).
