提供电源和网络连接：
a、 将电源线连接到两个CPU的螺钉端子L+和L-，以及
来自SS8xx的电源监控信号发送到螺钉端子SA和SB。
b、 将控制网络电缆连接至CN1（单总线连接），或
CN1+CN2（冗余总线连接）。控制网络是
连接到两个CPU。
c、 使用主电源的电缆TK212将控制生成器连接到COM4
CPU（如果需要更改IP地址等）。否则，连接
控制网络的控制生成器。
7.将光学模块总线连接到处理器单元上的光学触点
（参见32页图2和131页图40）。关于

8.通过将CPU连接到外部SB822电池提供电池备用
单位。按照安装SB822中的说明进行安装
144页的可充电外部电池单元。
两个CPU应由同一电源供电（单个或冗余）。对于
冗余电源，参见140页图46。CEX总线，用于将通信接口连接到处理器
单元位于处理器单元基板（TP830）的左侧。
总线终端装置必须始终安装在CEX总线上的后一个装置上，如
如80页图25所示。TB850公CEX总线终端单元为
随每个PM8xx/TP830处理器单元提供。
但是，如果配置需要使用TK850延长电缆，如
如81页图26所示，TB851母CEX总线终端单元为
需要，并且必须安装到顺序中的后一个底板上。TB851女性
每个TK850延长电缆均配有CEX总线终端装置。
TK850 CEX总线延长电缆
任何一条CEX总线中只能使用一条TK850 CEX总线延长电缆。
电缆长度：0.7米（2.3英尺）。
安装CEX总线互连单元BC810/TP857
BC810单元必须直接安装到处理器单元上的CEX总线
底板。SM810（如果使用）和通信接口安装到
BC810上的CEX总线，每端均端接TB850公CEX总线
终端单元。两个BC810通过互连电缆连接
TK851。
连接到BC810的CEX总线单元的大数量为六个。这个
BC810的主要功能是将CEX总线划分为两个物理上独立的总线
增加系统可用性的段，一个段上出现故障的CEX总线单元
不会影响处理器单元或其他CEX总线段。也是
需要注意的是，当将BC810与冗余CEX Bu一起使用时

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.
Both CPUs should be powered from the same supply (single or redundant). For
redundant power supply, see Figure 46 on page 140. 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-Bu
