38、l installations either indoors or outdoors and to associated electronic extension units. It applies to HBES switches for the operation of lamp circuits and the control of the brightness of lamps (dimmers) as well as the control of the speed of motors (e.g. those used in ventilating fans) and for oth
39、er purposes (e.g. heating installations ), to sensors, actuators, switched-socket-outlets, associated electronic extension units, etc In the following document the word “ HBES switch “ is applied to describe all kind of HBES devices e.g. switches, sensors, actuators, switched-socket-outlets, associa
40、ted electronic extension units, etc. The operation and control are performed intentionally by a person via an actuating member, a key, a card, etc., via a sensing surface or a sensing unit, by means of touch, proximity, turn, optical, acoustic, thermal, by physical means, e.g. light, temperature, hu
41、midity, time, wind velocity, presence of people, by any other influence; and transmitted by an electronic signal via several media, e.g. powerline (mains), twisted pair, optical fibre, radio frequency, infra-red, etc HBES Switches complying with this standard are suitable for use at ambient temperat
42、ures not normally exceeding 25 C, but occasionally reaching 35 C. Functional safety aspects of HBES switches are not covered by this standard. Functional safety requirements shall be covered by the standards of the devices which are controlled by the HBES. In locations where special conditions preva
43、il, e.g. higher temperature, special constructions may be required. NOTE 1 This annex is not intended to cover devices falling within the scope of IEC 60730. NOTE 2 Electronic switches without a mechanical switch in the main circuit do not provide a “full off-state“. Therefore, the circuit on the lo
44、ad side should be considered to be live. NOTE 3 HBES-switches to be connected to telecommunication networks should fulfil the relevant standard. 2 Normative references Annex ZA of Part 2-1 is applicable with the following additions: EN 50065-1, Signalling on low-voltage electrical installations in t
