IEC 63044-3:20 17除了HBES/BACS设备的产品安全标准外，还提供了与HBES/BACS网络相关的电气安全要求。它也适用于在HBES/BACS网络中使用的不存在特定HBES/BACS产品安全标准的器械。此外，它还定义了打算连接到HBES/BACS网络的设备接口的安全要求。它不适用于到其他网络的接口。 注其他网络的一个例子是IEC 62949涵盖的专用ICT网络。本文件适用于 操作员站和其他人机界面设备， 用于管理功能的设备， 控制装置、自动化站和专用控制器， 现场设备及其接口，以及 设备的布线和互连 在专用HBES/BACS网络中使用。本文件涵盖以下要求和合规性标准: 防止设备中的危险； 防止网络过电压； 接触电流保护； 防止不同类型电路造成的危险； 防止通信线路因电流过大而过热。 关键词:家庭自动化智能家居智慧城市

IEC 63044-3:2017 provides the electrical safety requirements related to the HBES/BACS network in addition to the product safety standards for HBES/BACS devices. It also applies to devices used within an HBES/BACS network for which no specific HBES/BACS product safety standard exists. In addition, it defines safety requirements for the interface of equipment intended to be connected to an HBES/BACS network. It does not apply to interfaces to other networks.
NOTE An example of other networks is a dedicated ICT network covered by IEC 62949. This document is applicable to

• operator stations and other human–system interface devices,
• devices for management functions,
• control devices, automation stations and application-specific controllers,
• field devices and their interfaces, and
• cabling and interconnection of devices

used within a dedicated HBES/BACS network. This document covers the following requirements and compliance criteria:

• protection from hazards in the device;
• protection from overvoltages on the network;
• protection from touch current;
• protection from hazards caused by different types of circuit;
• protection of the communication wiring from overheating caused by excessive current.
