DIN EN IEC 63044-3:2018-04

This IEC standard 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. This IEC standard 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 IEC standard 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. The responsible committee is DKE/K 716 "Elektrische Systemtechnik für Heim und Gebäude (ESHG)" ("Home and Building Electronic Systems (HBES)") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
