将RCU链路电缆TK851连接到两个CPU。请注意，在冗余
CPU配置、COM3和底板can上的电气模块总线
不使用。
6.底板电缆连接：
a、 将电源引线连接到CPU和电源监控信号
从SS8xx到螺钉端子SA和SB（参见83页图28）。
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

8.CPU配有内部备用电池。当电池用完时
如需使用，将其放入内部电池支架中（图63）。

系统安装。Connect the RCU Link Cable TK851 to both CPUs. Note that in redundant
CPU configuration, COM3 and the electrical ModuleBus on the baseplate can
not be used.
6. Baseplates cable connections:
a. Connect the power leads to both CPUs and the power supervision signals
from SS8xx to screw terminals SA and SB (see Figure 28 on page 83).
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.
Note that the RCU Link Cable TK851 must be used and can not be replaced by a
similar cable. Using another cable will disable the identification of the CPUs in
the CB and Operator Station. When running in single configuration the RCU
Link Cable TK851 might temporarily be used to perform the function of a
termination plug.
The CPU connected to the RCU Link Cable connector marked “UPPER” will be
defined as “UPPER” in the Control Builder and Operator Station. The marking
has no relevance to the physical placement of the CPUs. Any CPU can become
the Primary CPU.
Both CPUs should be powered from the same supply (single or redundant). For
redundant power supply, see Figure 46 on page 140.
Connection to the optical ModuleBus is identical to that for the processor unit
and for the FCI in S800 I/O (Figure 55 on page 161).

8. The CPUs are supplied with internal back-up batteries. When the batteries are
to be used, place them in the Internal Battery Holder (Figure 63 on page 193).
When the external SB821/SB822 battery units are to be used, install them
according to the instructions in Installing the SB821 External Battery Unit on
page 143/Installing the SB822 Rechargeable External Battery Unit on page
144.
Do not place the internal back-up battery in the battery holder until the AC 800M
Controller has been powered-up normally and the memory back-up function has
been activated, that is, the B(attery) LED flashes. If no normal power supply is
connected to the processor unit with the battery in place, then the CPU memory
will immediately start to consume battery power.
Always install a fresh internal or external battery at the end of the installation
phase. The original battery is heavily utilized due to frequent blackouts during
system installation.
