Figure 59. Terminals and connections between the star-coupler board, ASIC boards and feedback boards
(CH64 and CH74)
NOTE! The minimum optical cable bending radius is 50 mm.
NOTE! Terminals X2 and X3 can be in use simultaneously. However, if the +24 V supply from the
control 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 the
cables.
Fasten the removed cover(s) on the inverter module when the work is finished.
6.3.3 Connections between mains device and inverter power module
The dimensions in the table below must 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-
Cooled inverter.
Be careful when connecting the fibre optic cables! Connecting the wires
incorrectly may damage power electronic components.
