其外部电源连接器。此外部连接器还可以支持
具有冗余电源的CEX总线。
如果在BC810的冗余配置中使用外部连接器，则有
两种有效连接可能性：
•处理器单元和BC810的单电源（SD8xx或SS8xx）
在两个段（即段A和B）上。参见102页图33。
•段A上处理器单元的一个电源（SD8xx或SS8xx），以及
B段上的BC810，以及用于
段B上的处理器单元和段A上的BC810。参见图34

The BC810 is powered either from the processor unit via the CEX-Bus or through
its external connector for power supply. This external connector can also support the
CEX-Bus with redundant power.
If the external connector is used in a redundant configuration of BC810, there are
two valid connection possibilities:
• Single power source (SD8xx or SS8xx) for the processor units and the BC810s
on both the segments (say, segments A and B). See Figure 33 on page 102.
• One power source (SD8xx or SS8xx) for the processor unit on segment A and
the BC810 on segment B, and another power source (SD8xx or SS8xx) for the
processor unit on segment B and the BC810 on segment A. See Figure 34 on
page 103.
Do not connect the two CEX-Bus segments, separated with BC810, to each other
with CEX-Bus extension cable TK850.
For obtaining redundant power supply, connect the external connector to the
SS82x voting device. For details of SS82x connections, see Installing the
SS823/SS832 Voting Unit on page 136. See also Powering from an External
Source on page 176.
In AC 800M High Integrity Controllers it is required that the external supply
input of BC810 is connected and that the power supply is strictly configured
either according to Figure 33 or according to Figure 34 and nor is it allowed to
change the configuration by way of for instance individual circuit breakers
between modules.

Hot swap of the BC810 located next to a primary or single controller CPU,
otherwise called “direct BC810”, might jeopardize the whole controller and
should not be performed unless every module on the CEX-Bus are in a nonoperating state. Note: In an AC 800M HI controller this is unconditionally and
intentionally leading to a shutdown of the controller.
Hot swap of the BC810 not located next to a primary or single controller CPU,
otherwise called “indirect BC810”, will shut down any non-redundant interface
located on that CEX-Bus segment and should not be performed unless such
interfaces already are in a non-operating state or their function is dispensable for
the controller.

Installing SM810/TP855
The SM810 is mounted directly to the CEX-Bus on the processor unit base plate or
to the CEX-Bus interconnection unit BC810. The communication interfaces are
then mounted to the CEX-Bus on the SM810. See Figure 31 on page 100 and
Figure 32 on page 101 for configuration examples.
Digital I/O Connection
The SM810 has a connector with two digital inputs and three digital outputs that can
be used for High Integrity related digital I/O (not process I/O). See Table 10.
The input signals are used for system function, see AC 800M High Integrity
documentation.
In a redundant configuration, the corresponding digital inputs to both the
SM810’s must be connected to common digital input switches.
For example, the I2’s of both SM810’s must be connected to a common switch. If
separate sources are used, connect the sources to a common switch, and then
derive connections from the switch to both the SM810’s.
