Installation Procedure1. Access the optional module slots on the drive. Whenevernecessary, refer to the Hardware Manual of the drive forinstructions on removing any covers.2. Insert the module carefully into the slot marked with“DDCS” (BCU control unit slot 4) on the control boarduntil the retaining clips lock the module into position.3. Fasten the screws included in the package. Note thatcorrect installation of the screws is essential for fulfillingthe EMC requirements and for proper operation of themodule.4. Lead the fiber optic cables from the external device to theappropriate channel(s) of the RDCO. Inside the drive,route the cables as shown in its Hardware Manual. Makesure the cables are not kinked or laid against sharpedges. Observe colour coding so that transmitters areconnected to receivers and vice versa. In case multipledevices are to be connected to one channel, they mustbe connected in a ring.Technical dataModule types: RDCO-01(C), RDCO-02(C), RDCO-03(C),RDCO-04(C)Degree of protection: IP 20Ambient conditions: The applicable ambient conditionsspecified for the drive in its Hardware Manual are in effect.Connectors:• 20-pin pinheader• 4 transmitter/receiver connector pairs for fiber optic cable.Type: Agilent Technologies Versatile Link.
