Nel retro del gruppo di continuità sono predisposti i seguenti collegamenti:
• The following connection points are located on the rear of the UPS:
• Input/Output plug-socket (3): connect the power supply cable and the output extension so-
ckets to this connector.
• Socket for connection of RS 232 (9 pin female) type, computer serial interface (4): to be used if
the diagnostics software is utilized.
• Layout for connection of additional batteries [5]
WArning
For reasons of safety, we recommend the cables supplied not to be modified; in addition, it is
essential to ensure both that the mains outlet used for the UPS is connected securely to the
earth circuit and that a suitable protection is provided as per regulations.
WArning
The mains outlet, or the circuit breaker, must be installed near the appliance and must be
easily accessible.
Proceed with the installation as follows:
1) Locate the UPS so that the ventilation outlets are not obstructed.
2) Connect the power supply cable and the multiple-socket output extension to the Input-Ou-
tput connector (3) (see fig.2)
3) Check the on/off switches of all the appliances to be connected to the UPS are OFF and con-
nect them to the output extension.
4) Insert the power supply plug into a power outlet that is adequate for the voltage and current
required.
switching on
1) Switch the UPS on with the appropriate button (1) (refer to the section on ‘Functions and Si-
gnals’ at the paragraph ‘controls’): The UPS initially supplies the output directly with mains
power using its bypass (signalled by the yellow Status Indicator) (2) and after a few seconds
switches over to its inverter and enters its normal operation mode (the green Status Indicator
[2] is on).
2) Switch the connected loads on and, after any bypass intervention, check that normal opera-
tion is resumed: at this point the green Status Indicator [2] is on. Should the connected loads
be too large, the bypass will remain active and the red Status Indicator [2] will flash fastly.
3) A few moments after switching on, the UPS will automatically test its batteries to check if they
are operating correctly (refer to the section on the ‘Battery Test’).
