3. Installation
3.4.2 Single cabinet
1. Wire up the Input-Output connector supplied as shown in figure 3, using insulated cable with wires whose section is
at least 2.5 mm
2. Insert the connector into the plastic housing and secure it using the screws supplied. Secure the wires to the housing
using the cable grip (see fig. 3).
3. Take the cover off the plug [9] by removing its screws.
4. Put the Input-Output connector into the plug [9] located on the rear of the UPS, and secure to its case using the
screws supplied (see fig. 2).
5. Check that the on/off switches of all the appliances to be connected to the UPS are OFF and connect them to the
output socket.

WARNING
Your UPS is fitted with a circuit to protect it against the risk of incorrect connections.
This eventuality will be indicated by means of its red warning light, lit without flashing, and the continuous sounding
of its internal buzzer. Should you note this signal immediately after switching the UPS on, switch it off and remove
the power supply plug immediately.
3.4.3 Precautions for installation
• Electrical connections should only be done by trained personnel
• Do not modify the electric cables supplied
• Make sure that the mains outlet is connected securely to an earth circuit
• The mains outlet, or the circuit breaker, must be installed near the appliance and must be easily accessible
ATTENTION
(for versions 3 103 38 / 3 103 39 / 3 103 40 / 3 103 41)
The cables supplied are fitted with an input plug and outlet sockets whose maximum capacity is 16A.
Therefore, we recommend use of direct cabling from the control panel to the connector supplied (follow instructions
for connections shown in Figs. 3 and 4 on Pages 36-37) for applications where the anticipated UPS input current
will be in excess of 13A (e.g. 5000 VA with Vinn=184V).
ATTENTION
(for versions 3 103 38 / 3 103 39 / 3 103 40 / 3 103 41)
Since current dispersion towards earth of all the loads merges in the UPS protection wire (earth wire), it is essential
to check that the sum of these currents does not exceed 2.7 mA, according to standard EN 50091-1-1, for safety
