ELECTRICAL CABLING AND CONNECTIONS vacon • 1036Figure 59.Terminals and connections between the star-coupler board, ASIC boards and feedbackboards (CH64 and CH74)NOTE! The minimum optical cable bending radius is 50 mm.NOTE! TerminalsX2 andX3 can be in use simultaneously. However, if the +24 V supply from thecontrol I/O terminals (e.g. from board OPT-A1) is used, this terminal must be protected with a diode.Fix the cable bundle at two or more points, at least one at each end, to prevent damages to thecables.Fasten the removed cover(s) on the inverter module when the work is finished.6.3.3 Connections between mains device and inverter power moduleThe dimensions in the table below shall be taken into account if some kind of mains device (e.g.fuse, switch fuse, contactor) is used in the input line between the mains and the Vacon Liquid-Be careful when connecting the fibre optic cables! Connecting the wiresincorrectly may damage power electronic components.nxw13.fh11Star coupler board on control unitH18 Trip signal from power module 2H17 VaconBus data from ASIC 2 to control boardH16 VaconBus data from control board to ASIC 2H15 ADC synchronization, power module 2H14 Phase W control, power module 2H13 Phase V control, power module 2H12 Phase U control, power module 2H11 Gate control enable, power module 2H23 Feedback phase WH22 Feedback phase VH21 Feedback phase UTerminals on ASIC board of power module 1H1 Gate control enableH2 Phase U controlH3 Phase V controlH4 Phase W controlH5 ADC synchronizationH6 VaconBus data from control board to ASICH7 VaconBus data from ASIC to control boardTerminals on ASIC board of power module 2H8 Trip signal from power module 1H7 VaconBus data from ASIC 1 to control boardH6 VaconBus data from control board to ASIC 1H5 ADC synchronization, power module 1H4 Phase W control, power module 1H3 Phase V control, power module 1H2 Phase U control, power module 1H1 Gate control enable, power module 1H10 Trip signalTerminals on FB board of power module 2H1 Gate control enableH2 Phase U controlH3 Phase V controlH4 Phase W controlH5 ADC synchronizationH6 VaconBus data from control board to ASICH7 VaconBus data from ASIC to control boardH10 Trip signalH11 Feedback phase UH12 Feedback phase VH13 Feedback phase WTerminals on FB board of power module 1H 12H 13H 14H 15H 16H 17H 18H 11H 23H 22H 21H2H3H4H5H6H7H8H1H10 FB PM1H7 ASIC PM1H6 ASIC PM1H5 ASIC PM1H2 ASIC PM1H3 ASIC PM1H4 ASIC PM1H1 ASIC PM1H10 FB PM2H7 ASIC PM2H6 ASIC PM2H5 ASIC PM2H4 ASIC PM2H3 ASIC PM2H2 ASIC PM2H1 ASIC PM2H13 FB PM1H12 FB PM1H11 FB PM1Explanations of abbreviations:ASIC = ASIC boardFB = Feedback boardPM1 = Power Module 1PM2 = Power Module 211373_uk13006.emfPhone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
