The sections given in the table above are indicative only. The cables have been designed according to
the standard CEI-UNEL35024/1, using the following data:
70° C rated PVC copper cables
ambient temperature equal to 40° C
maximum length of the cables equal to 30 m (voltage drop < 0,5%)
cables laid in cavities of structures or solid bottom cable trays
The given cross sections do not take into account the overload currents allowed by each line, which are
detailed in the product Technical Specification.
The UPS manufacturer is not responsible for the correct sizing of the device supply and output lines for
which the plant conditions and operating temperatures, which are specific of each electrical installation,
must be taken into account.
