10.4 Cable Sizes
10.4.1 List of Cable Size Information
The 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. Use cable insulation that can withstand a temperature of at least 90 °C (194 °F). In other
conditions, refer to the local safety regulations, the input voltage, and the load current of the drive.
The cable size tables for the liquid-cooled system modules can be found with these links.
l 10.4.2 Field Cable Sizes for AFE and GC Modules, 525–690 V AC
l 10.4.3 Internal Cable Sizes for AFE and GC Modules, 525–690 V AC
l 10.4.4 Field Cable Sizes for INU Module, 525–690 V AC
l 10.4.5 Marine Cable Sizes for AFE or GC Modules 525–690 V AC
l 10.4.7 Marine Cable Sizes for INU Modules 525–690 V AC
l 10.4.6 Source Cable Sizes for DC/DC Converter Modules, 640–1100 V DC and 640–1200 V DC
10.4.2 Field Cable Sizes for AFE and GC Modules, 525–690 V AC
The AFE and GC modules with integration units do not have field cabling terminals for mains. Connect the AFE and GC modules to
adequate size field cabling terminals or switching device.
