Power Distribution System SVS8 Description The power distribution system SVS8 optimises the DC V distribution in automation and process control, in the production area of the chemical industry and in power plants. The power distribution system SVS8 DIN rail mounting distributes all voltage potentials supplied by a V power supply (SMPS) onto /0 ways F to F/F0 (arranged from right to left). The system offers integral redundancy diodes in each protected load output and selectively protects the connected loads such as controls, transformers, actuators, magnetic yoke subassemblies, bus modules etc. by means of the circuit breaker fitted. With a max. total current of A and a typical load current of 3 A per way (max. A in limited continuous duty) the SVS8 provides ease of distribution and sub-distribution in short-circuit-limited DC V applications. All auxiliary contacts (make contacts) of the plugged-in circuit breakers are connected in series and allow group signalling in accordance with the closed-circuit principle. The protected»l+«load outputs with redundancy diodes per way significantly reduce the otherwise standard wiring time. All terminals of the DC V supply, load outputs with 0 V return conductor as well as the signalling terminals are screwless spring-loaded terminals. Suitable for the following E-T-A circuit breaker types: electronic circuit breaker ESS0-00DCVmax. A electronic circuit breaker ESS30-0DCVmax. A electronic circuit protector ESX0-0DCVmax.

Power Distribution System SVS8 Notes Mounting position l The max. total current of A must not be exceeded. l The max. current load of the redundancy diodes of typically. A, max. 3 A per diode, must be strictly observed. In the event of parallel connection of the two diodes, a load current of typically 3 A (max. A in limited continuous duty) must strictly be observed. l The signal circuit (max. 0. A) has to be protected separately or supplied via the current-limited DC-o.k.-output of a switch-mode power supply. l Jumpers type SB-S-P-0--A have to be inserted into free slots. l The user has to ensure that the proper cable cross section of the load circuit in question is chosen in relation to the rating of the load / circuit breakers. l Technical data of the circuit breakers have to be observed. l In addition special precautions have to be taken in the plant or machinery (e.g. use of a safety PLC) to prevent inadvertent startup of (parts of) the system (cf. Machinery Directive 00//EG and EN 00, Safety of Machinery). In the event of a failure (short circuit/overload) the load circuit will be disconnected by circuit breakers. l The power distribution system must only be installed by skilled personnel. l It is exclusively meant for the use with low voltages (= V). l Only after expert installation may the assembly be connected to a power supply. l After tripping of the circuit breaker and before reset, the cause of the tripping (short circuit or overload) must be remedied. l The national and international standards (e.g. DIN VDE 000 for Germany) must be observed with respect to installation and selection of cables. l Connection to higher or not reliably disconnected voltages may be hazardous or cause damages. Caution: Warning of hot surface, the diodes could be hot, do not touch risk of injury. 33 www.e-t-a.de 3

Power Distribution System SVS8 Application example: jumper instead of circuit breaker (e.g. ESX0-003) If the power distribution system is not completely populated with circuit breakers, the open way can be closed with a plugged-in jumper type SB-S-P-0--A. The signalling pathway of the group signalling is as follows: - feed-in of DCV potential in X3 terminal (3) - via all aux. make contacts / of the fitted circuit breakers type ESX0-03 (or ESS0-003, ESS30-03) - back to the signal outputs of the group signal X3(////) In operating condition (i.e. all circuit breakers plugged in and ON) the signalling pathway from X3/3 to X3/ is closed.
