Circuitry for emergency lighting according to claim 1 or 2, characterized in that NL-L ‘the two end circuit common to the combined final circuits LN, L N have a common return conductor N have. Portable power and signal distribution system for a controllable system including multiple devices. Switch box for data and power transfer in factories, workshops and assembly halls. Cable entries into buildings in public cable network.
For this purpose, in each output circuit of the junction box fuses are arranged, which cause not a short circuit in one end circuit further supplied from the distribution end circuits to be disturbed. Advantageous embodiments and further developments are contained in the dependent claims. However, this requires both interventions at the headquarters of the power supply as well as in the individual lights, turn a lot of effort.
Fundamental principles, assessment of general characteristics, definitions. A round body, the back of the hand 50 mm in diameter, solid foreign body of 50 mm in diameter. Application deemed withdrawn, or ip right lapsed, due to non-payment of renewal fee.
Instead of the conductor 4 only 3 conductors may be used with a common neutral conductor. Es ist nach VDE erforderlich, die Leuchten derartiger Stromkreise auf zwei gesondert abgesicherte Stromkreise, alternierend angeordnet, aufzuteilen.
The switch-on for a final circuit in standby operation, the failure of the general power supply can be the failure of a sub-distribution tejl the general power supply or even a light requirement. Is switched parallel to the first circuit. Blei-Akkumulatoren-Starterbatterien – Teil 1: It is necessary in accordance with VDEthe lights of such circuits on two separately fused circuits, alternately teol to divide.
Depending on whether the light permanently switched z.
DEB4 – A circuit arrangement for the emergency lighting – Google Patents
Loose Flange PN Emergency lighting system for buildings and rooms with official nature, has lights of different operating phases, where emergency lighting system is connected to supply line and switch units are arranged in fire area. The respective output circuits are in turn divided into vce first and a second circuit.
01008 The object of the invention is therefore to find a circuit arrangement for supplying the emergency lights, wherein the number of the necessary terminal circuits and the length of the function-maintaining cables to be installed can be reduced. PVC insulated cables and sheathed power cables for rated voltages up to and etil. Both circuits are used for protection against overcurrents to final circuits, because a fault in a circuit not affected by the inventive arrangement of fuses S1, S2, S3 and S4, the function of the second circuit.
The object is achieved by a circuit arrangement having the features of claim 1. Ancillary equipment – Protective conductor terminal blocks for copper conductors. A second circuit L’-N using the neutral conductor of the first circuit as a common return conductor.
German DIN VDE Standards
General requirements and particular requirements for clamping units for conductors from 0,2 mm2 up idn 35 mm2 included. B Wegeleuchten zur Beleuchtung von Rettungswegen. Je nachdem ob die Leuchte in Dauerschaltung z. By this measure, it has become possible now to mix modes of lights in a final circuit, thus saving a final circuit over conventional wiring. Performance requirements and testing methods.
According to the invention a feed line z. According to the invention the required according to the prior art lead to the emergency lights with 4 final circuits is replaced by a single supply line with subsequent distribution box for the connection of the now shortened and reduced in the number of lines of the final circuits. This is particularly complicated when the final circuits must be run function-maintaining spatial bridge of fire compartments. Sewers and Drains in Water Catchment Areas Ancillary equipment – Safety requirements twil fuse terminal blocks.
Is a function preserving against the effects of fire line. IEC EN Connecting devices – Electrical copper conductors Safety requirements for screw-type and screwless-type clamping units – Part 2: Welding Neck PN Spring clamp connections – General requirements, test methods and practical guidance.
