Connection to the computer interface
The UPS can be connected to the serial port on the computer so as to monitor and guarantee correct
shutdown of the computer in cases of power failure.
N.B.: Connection of the computer interface is optional. In fact, the UPS will operate even without this
connection.
Connection to the telephone/modem line protection jacks
A single telephone or modem line may be connected to the jacks that protect against overvoltage on the rear
of the UPS. The modular RJ-45/RJ-11 jacks are compatible with standard single telephone connections.
Connection to the line protection jacks requires a telephone extension cable (supplied).
N.B.: The connection is optional. The telephone/modem line protection is effective even if the UPS is
switched off or disconnected from the mains.
Warning: The overvoltage protection device for telephone lines may not work if it is not installed
correctly. Make sure that the telephone wall cable is inserted in the connector marked "IN" and that the
cable of the unit to be protected (telephone, modem, etc.) is inserted in the connector marked "OUT".
Warning: The overvoltage protection device is only for use in closed environments; do not connect
telephone wires during a storm
N.B.: The protection device limits the effects of overvoltage, but does not guarantee total protection.
OPERATION
Switching On
After connecting the UPS to the mains outlet and the loads to the UPS, press the ON/OFF button to turn the
UPS on. The green "Line Active" LED will come on.
The UPS can be switched on even in the event of a power failure with the same procedure, but instead of the
green LED the yellow "Battery Mode" LED lights up and an intermittent audio signal sounds.
NOTE: In cases of blackout, the yellow "Battery Mode" LED comes on and at the same time the UPS
sounds an audio signal. If the blackout persists, and the battery runs low, the audio signal will sound at a
faster rate.
When battery power is down to a minimum, the UPS automatically disconnects the batteries and switches
off.
Switching Off
To switch the UPS off, press the ON/OFF button. The "Line Active" or "Battery Mode" LED's go off and
the loads are disconnected.
