DANSK DSF/EN IEC 63044-3/PRA1 PDF

IEC&nbsp;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&emsp;An example of other networks is a dedicated ICT network covered by IEC&nbsp;62949. This document is applicable to <ul> <li> operator stations and other human&ndash;system interface devices,</li> <li> devices for management functions,</li> <li> control devices, automation stations and application-specific controllers,</li> <li> field devices and their interfaces, and</li> <li> cabling and interconnection of devices</li> </ul> used within a dedicated HBES/BACS network. This document covers the following requirements and compliance criteria: <ul> <li> protection from hazards in the device;</li> <li> protection from overvoltages on the network;</li> <li> protection from touch current;</li> <li> protection from hazards caused by different types of circuit;</li> <li> protection of the communication wiring from overheating caused by excessive current.</li> </ul> Key words: Home automation, smart homes, smart cities
