CAUTION
The choice of the type and section of the power cables must be done according to the voltage and rated current as well
as the local wiring standards and regulations. It is a responsibility of the installation engineer.
The input current and the output power of the UPS are indicated in chapter 10 and the battery current in table 4 of this chapter.
The following tables give an indication of the wire cross sections to use if the wires are unipolar with simple PVC installa-
tion and installation in tube in the air.
