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,</li>
devices for management functions,</li>
control devices, automation stations and application-specific controllers,</li>
field devices and their interfaces, and</li>
cabling and interconnection of devices</li>
used within a dedicated HBES/BACS network. This document covers the following requirements and compliance criteria:

protection from hazards in the device;</li>
protection from overvoltages on the network;</li>
protection from touch current;</li>
protection from hazards caused by different types of circuit;</li>
protection of the communication wiring from overheating caused by excessive current.</li>
Key words: Home automation, smart homes, smart cities
