General Cable Size Information

10.4.1
The IEC cable sizing is based on the ambient temperature of 40 °C (104 °F), cables laid side by side on cable ladders, maximum 9 cables
per ladder, and 3 ladders on top of each other. The cables are XLPE insulated, with a maximum conductor temperature of 90 °C (194 °F).
In other conditions, refer to the local safety regulations, the input voltage, and the load current of the drive.
The UL cable sizing is based on the ambient temperature of 40 °C (104 °F), 75 °C (167 °F) rated copper cables, and multicore cables
installed raceways or not stacked or bundled longer than 600 mm (24 in) without maintaining spacing. In other conditions, refer to the
local safety regulations, the input voltage, and the load current of the drive.
Use symmetrical cabling with system modules connected in parallel. Each module must have the same number of cables with an
equal cross-section.
