PRESENTATION
This manual describes the Dialog Vision UPS family (DVT, DVR, DVD) and their related battery box.
The Dialog Vision is a line-interactive UPS.
The UPS protects equipment connected to it from:
a) mains power supply failures
b) surges
c) sags and brownouts
The UPS automatically corrects its output for small fluctuations in the mains power supply. In the event of larger
fluctuations or a complete mains power supply failure, its output is powered from the inverter drawing energy
from the internal battery set
The UPS can operate from a mains power supply even if there is no battery available. In this instance all other
functions (AVR, start-up or shutdown and overload protection) are available.
CHARACTERISTICS
Sinusoidal output voltage
Front panel LCD
Microprocessor control for high reliability
High frequency technology
Automatic correction of input voltage fluctuations by the built-in Automatic Voltage Regulator (AVR). The
AVR, compensates for input voltage variations within a defined input voltage window and maintains a
stable output, without resorting to batteries. Using the batteries less frequently ensures that they are at full
capacity when they are actually needed and helps them to last longer.
Selectable output range
Cold start
Integrated volt-free contacts/RS-232/USB port
Back-up time can be increased by adding a battery box (DVD 2200VA/3000VA models only)
Overload, short-circuit and overheating protection
Configurable as Rack or Tower (DVD models only)
Models DVR and DVD suitable for installation in 19” rack cabinets

INSTALLATION
CONNECTION
Connect the UPS to the mains power supply using the input supply cable. Connect the loads to the UPS sockets
with the IEC-IEC cables or with a similar cable with a maximum length of 10 metres.
Note: do not connect loads that draw more than 10A, to the 10A IEC sockets. These loads can only be
connected to the 16A IEC socket (where fitted).
CONNECTION TO THE NET/TEL PROTECTION DEVICE
A telephone/modem/network line can be connected to the modular RJ-45/RJ-11 connectors (located on the rear
of the UPS) to protect against surge voltages. A telephone extension cable is required for this type of
connection.
N.B.: This connection is optional. The Net/Tel protection is active even when the UPS is switched off or
disconnected from mains power
Warning: The device that protects against overvoltages on the telephone line may not work if it is not installed
correctly. Ensure that the telephone line from the wall is inserted in the connector marked “IN” and that the cable
of the device to be protected (telephone, modem, network card, etc.) is inserted in the connector marked “OUT”.
N.B.: This protection device limits the effects of an overvoltage but does not guarantee absolute protection.
POWERSHARE
All the models of the Dialog Vision range are provided with an auxiliary output socket that can be configured via
UPSTools. The Powershare socket can be configured in five different ways (refer to the UPSTools manual) as
described below:
ALWAYS: (standard configuration), the Powershare socket is always active; the load is powered, as if it
were connected to one of the other output sockets.
BATTERY LOW: the Powershare socket is normally active, but after 10 seconds from the start of the
battery low signal, the Powershare socket is deactivated.
BATTERY WORKING: the Powershare socket is active if the UPS is powered from the mains power
supply, if the UPS is working in battery mode; the Powershare socket is deactivated.
BATTERY WORKING DELAYED: the Powerashare socket is always active, but after 1 minute of
operation in battery mode or after 10 seconds in a battery low condition, the Powershare socket is
deactivated.
BUZZER: when the UPS is working in battery mode, the Powershare socket is activated and deactivated
in the same way as the buzzer.

51
INSTALLATION
INSTALLING THE EMERGENCY POWER OFF (EPO)
The DVR and DVD range are provided with an EPO contact. This allows the UPS to be shut down immediately
without having to wait for the shutdown procedure to be completed.
Note: When the UPS has been switched off using this input, it is not be possible to switch the device back on
again (even if the EPO contact is closed) until the UPS has been restarted manually. If the EPO contact is open,
the UPS will not restart even if the ON key is pressed.
Follow the procedure below to install the EPO switch:
1. Check that the UPS is switched off.
2. Disconnect the EPO input terminal from the UPS.
3. Remove the jumper fixed to the terminal.
4. Apply a volt-free contact signal (isolated and normally closed Vmax: 60 Vdc, 30 Vac RMS; Imax: 20mA),
between Pin 1 and 2 of the terminal, using an unshielded wire of diameter 18-22 AWG (0.75 mm2– 0.3mm2).
5. Reconnect the terminal to the EPO input.
6. Ensure that the switch connected to the EPO contact cannot be activated by a device powered by the UPS.
7. Connect the UPS to the mains power supply and switch it on using the ON key.
8. Activate the EPO contact by means of the external switch to ensure the UPS shuts down.
9. Deactivate the EPO contact by means of the external switch and restart the UPS.
INSTALLING AN ADDITIONAL BATTERY BOX
The DVD 220 and DVD 300 models are provided with a connector that allows an external battery box to be
connected to the UPS to increase the back-up time available.
Note: When connecting additional batteries a small spark may occur within the connector when the
cable is connected.
Follow the procedure below to install the additional battery box.
1. Connect the cable to the battery connector at the back of the battery box.

52
INSTALLATION
2. Then connect the other end of the cable to the battery connector at the back of the UPS.
3. To add further battery boxes (up to a total maximum capacity of 120Ah), repeat the previous
steps.
Note: When a battery box is installed, the UPS must be configured for the correct total capacity of the batteries
(using UPSTools software) in order to calculate correctly the remaining back-up time and the battery charge. The
configuration must be done with the UPS switched on or in stand-by mode.
For this kind of battery box the value to be added is “9”[Ah].
For the DVD 220/300 models whose total battery capacity has not been increased, the recharge current is 2 A.
After setting the nominal battery capacity with the UPSTools software, if the value set is greater than 14 Ah, the
recharge current automatically increases to 6 A.
START-UP/SHUTDOWN
To start up and shut down the UPS, press the ON and OFF switch for at least three seconds.
Starting up for the first time: after about 30 seconds, check that the UPS is working properly:
1. Simulate a mains power supply failure by unplugging the input power cable
2. The load must continue to receive power, the battery mode indicator should light up and the UPS
should beep every 4 seconds.
3. Reconnect the power cable. Normal mains power operation should be restored.
START-UP FROM BATTERY
The UPS can be switched on even when no mains power supply is available and the battery is fully charged.
Just press ON for at least three seconds to start the UPS.
RECHARGING
The UPS is supplied with fully charged batteries. During shipping, however, they can lose some of their charge
and so the batteries must be recharged before use. Connect the UPS to the mains power supply and leave the
UPS to recharge for at least 8 hours before discharging it.
