Connecting the motor cables (units without common motorterminal cubicle or sine output filter)On units without a common motor terminal cubicle or a sine output filter, the motor cablesconnect to busbars located behind the inverter module(s). The location and dimensions ofthe busbars are visible in the dimension drawings delivered with the drive, as well as theexample drawings presented in this manual in chapter Dimensions.To allow the most room for the work, the modules can be removed completely from thecabinet. For instructions, see section Removing the inverter module(s) (page 111).Especially in the case of multiple inverter modules in the same cubicle, you can consideronly removing the fan carriage of each module. This is faster than removing the entiremodule, but allows less room for the connecting work. For instructions, see section Removingand reinstalling the fan carriage of an inverter module (page 115)If the drive is equipped with a common motor terminal cubicle (option +H359) or a sineoutput filter (option +E206), follow the instructions in sectionConnecting the motor cables(units with common motor terminal cubicle or sine output filter) (page 119).￭ Motor connection diagram (without option +H366)All parallel-connected inverter modules are to be cabled separately to the motor. 360°earthing is to be used at cable lead-throughs.U2V2W2PEU2V2W2M3~U1W1V1PEInverter unit cubicle(s)The recommended cable types are given in chapter Output cable sizes.WARNING!The cabling from all inverter modules to the motor must be physically identicalconsidering cable type, cross-sectional area, and length.Electrical installation 109
