INSTALLATION

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 sockets to this con-
nector, as indicated in the diagram.
• Socket for connection of RS 232 (9 pin female) type, computer serial interface [5]: to be used if the 'Su-
perviSor light' UPS diagnostics software is required.
• 1 socket to connect the remote control and the computer interface to logic signals ( contacts) [4]: for use
with the respective accessoires (optional)
For reasons of safety, we recommend the cables supplied are not modified; in addition it is essential to en-
sure that the mains outlet used for the UPS is connected securely to the earth circuit.
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-Output connector [3]
(see fig.1)
3) Check that the on/off switches of all the appliances to be connected to the UPS are OFF and connect 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 Signals' at the pa-
ragraph 'controls'): The UPS initially supplies the output directly with mains power using its bypass (si-
gnalled by the yellow LED) [2] and after a few seconds switches over to its inverter and enters its normal
operation mode (the green MAINS LED [2] is on).
2) Switch the connected loads on and, after any bypass intervention, check that normal operation is resumed:
at this point the green MAINS LED [2] is on. Should the connected loads be too large, the bypass will re-
main active and the red ALARM LED [2] will flash.
3) A few moments after switching on, the UPS will automatically test its batteries to check they are operating
correctly (refer to the section on the 'Battery Test').
Never remove the 230 V power plug whilst the UPS is in operation: this would disconnect the earth protec-
tion of both the UPS and of the connected loads.
Since current dispersion towards earth of all the loads are added together in the UPS protection connector
(earth wire), it is essential to check that the sum of these currents does not exceed 2.7 mA for safety rea-
sons, according to standard EN 620401-1.
If the red ALARM LED flashes briefly every 3 seconds after all the connected loads are switched on, it is to
signal that the load connected to the UPS is at the limit of toleration.

FUNCTIONS AND SIGNALS

Luminous signals:
With reference to the diagram on page 12, the luminous signal [2] has the following functions:
• Green MAINS LED
• On fixed: mains is regular, inverter is synchronous.
• Flashing: mains is out of tolerance, but present and sufficient for correct operation, or inverter is not
synchronous.
• Off: mains is not present or too low in respect to the load.
