7.4.1 Connecting the Optic Fiber Cables, FR10–FR12
In case the fiber cables are not connected, connect them from the optical fiber board (FR10–FR11) or star coupler board (FR12) to
the power unit.
DAMAGE TO THE COMPONENTS FROM INCORRECT CONNECTIONS
Connecting the cables incorrectly damages power electronic components.
-
Be careful to connect the fiber optic cables according to instructions.
The maximum length of the optical cable is 8 m.
The minimum bending radius for optical cables is 50 mm.
Procedure
1.
To access the ASIC board, remove the cable cover in front of the power unit.
2.
Connect the supply cable to the X10 connector on the ASIC board and to the X2 connector on the rear side of the control
unit. For FR12, connect only power unit 1. Power unit 2 is connected to ASIC load resistor.
Terminals X2 and X3 can be in use simultaneously. However, if the +24 V supply from the control I/O terminals (for exam-
ple, from board OPTA1) is used, this terminal must be protected with a diode.
