Each fibre optic cable has a number 1...7 marked on the cable shield at both cable ends. Connect
each cable to the connectors marked with the same number 1...7 on the ASIC board and on the rear
side of the control unit.
Optical terminals on Optical cable adapter board
:
Other terminals on adapter board
:
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.
