UPS EVO DSP PLUS TM 21 User’s manual
If UPS is used daily, it is recommended to leave the Input circuit breaker always “ON” and use the ON and OFF
buttons on the front panel to activate/deactivate the Inverter.
If the UPS has to be turn OFF for several days, it is recommended to turn “OFF” the Input circuit breaker.
If the ON button is pressed when AC Input is not present, the UPS switches ON even, and works in Battery mode
after about 4 seconds.
If the OFF button is pressed when AC Input is not present, then the Inverter switches OFF and consequently there
will be no Output power.
In Bypass mode, the Inverter is NOT ACTIVE and the UPS doesn’t work as an UPS, but
only as a Bypass between Input and Output power lines.
In Bypass mode, the UPS supplies the load only if AC Input is present. In Bypass mode
the Output load isn’t protected in case of black-out.
8.2 Low Battery and Automatic Restart
The UPS reaches the
Low Battery
condition whenever, during working in Battery mode, the batteries reach a
charge level allowing the connected devices to operate for few minutes more.
The UPS warns operators of Low Battery by lighting of the LOW BATT. icon on the graphic LCD 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 4 seconds it
goes back to work in Normal mode.
After a complete discharge, the UPS needs 10 hours to recharge completely the batteries. The UPS recharges
batteries automatically if it works in Normal mode or in Bypass mode.
8.3 Load Testing
The UPS indicates the Output Load level by graphic LCD (on the right side as described in the chapter 5).
When the Output load is higher then nominal value the UPS warns of Overload condition by graphic LCD and by
acoustic alarm as described in the “Warning Table” and in the “Troubleshooting” chapter.
The UPS has the capability to accept an Overload less than 110% for 10 minutes.
An Overload between 110% and 130% is accepted for about 1 minute and after UPS switches automatically to the
Bypass mode.
An Overload higher than 130% is accepted for 1 second and after the UPS switches automatically to the Bypass
mode.
Once the requested power is back within range, the UPS switches automatically to the 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.
