Provide connections for power supply and network: a. Connect the power leads to screw terminals L+ and L- of both CPUs, and the power supervision signals from SS8xx to screw terminals SA and SB. b. Connect the Control Network cables to CN1 (single bus connection) or CN1 + CN2 (redundant bus connection). The Control Network is connected to both CPUs. c. Connect the Control Builder to COM4 with cable TK212 of the Primary CPU (if required for changing an IP address etc.). Otherwise connect the Control Builder to the Control Network. 7. Connect the optical ModuleBus to the optical contacts on the processor units (see Figure 2 on page 32 and Figure 40 on page 131). Information regarding optical cable selection and cable length is provided in the S800 I/O documentation. 8. Provide battery backup by connecting the CPUs to the external SB822 battery units. Install them according to the instructions in Installing the SB822 Rechargeable External Battery Unit on page 144.
The CEX-Bus, used for connection of communication interfaces to the processor unit, is located on the left-hand side of the processor unit baseplate (TP830). A bus termination unit must always be fitted to the last unit on the CEX-Bus, as shown in Figure 25 on page 80. A TB850 male CEX-Bus termination unit is supplied with each PM8xx/TP830 processor unit. However, should the configuration require the use of a TK850 extension cable, as shown in Figure 26 on page 81, then a TB851 female CEX-Bus termination unit is required and must be fitted to the last baseplate in the sequence. A TB851 female CEX-Bus termination unit is supplied with each TK850 extension cable. TK850 CEX-Bus Extension Cable Only one TK850 CEX-Bus extension cable may be used in any one CEX-Bus. 
Cable length: 0.7 m (2.3 ft). Installing the CEX-Bus Interconnection Unit BC810/TP857 The BC810 units must be mounted directly to the CEX-Bus on the processor unit base plate. The SM810, if used, and communication interfaces are then mounted to the CEX-Bus on the BC810, and terminated in each end with TB850 male CEX-Bus termination unit. The two BC810 are connected with the interconnection cable TK851. The maximum number of CEX-Bus units connected to a BC810 is six. The primary function of BC810 is to divide the CEX-Bus into two physically separate segments for increased system availability, a faulty CEX-Bus unit on one segment will not affect the processor unit or the other CEX-Bus segment. It is also important to note that when using the BC810 together with redundant CEX-Bus units these units shall be mounted on different BC810 CEX-Bus segments.
