Power distribution system SVS Description The new power distribution system type SVS meets all requirements of the automation technology with regard to reliably overcurrent protection and optimised current distribution. NEW The track-mountable power distribution system SVS distributes the voltage potentials supplied by a DC V switch-mode power supply to slots and selectively protects the connected loads by means of the plugged in circuit protector type REF-S0-DCV. The SVS simplifies wiring and distribution with a load current of 0A per way and a max. total current of 0A in short-circuit-limited DC V applications. 0 protected»+«load outputs and 0 minus terminals per slot help significantly reduce wiring time. Any load circuit which might be disconnected due to overload or short circuit generates a single signal which will be summarised in a group signal directly on the power distribution system and which will be fed back directly to the control unit. The line entry for the DC V supply as well as the load output terminals are designed as push-in terminals so that the entire system can be wired quickly and cost-effectively. Suitable for the following types: Electronic circuit protectors Features and Benefits l Systematic integration of protection and distribution functions l Power distribution and selective protection of DC V load circuits all in one l Clearly laid-out distribution concept l Profitability through considerably reduced wiring time l Reduction of planning, design and installation time l Ease of maintenance, diagnosis and system extension l Compact power distribution for compact control cabinets l 0 plus and minus terminals per slot l Integral group signalling Order numbering code Type SVS SVS power distribution system for REF-S l for short-circuit limited DC V applications l max. 0 A cont. load l group signalling terminals X included, DCV / max. 0.

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 the circuit protector. l The power distribution system must only be installed by qualified personnel. l It is only intended for use with safety extra-low voltage (= V DC). l Only after expert installation must the device be supplied with power. l After tripping of the circuit protector, before reset, the cause of short circuit or overload has to be remedied. l The national standards (e.g. for Germany DIN VDE 000) have to be observed for installation and selection of feed and return cables. l Connection to a higher or not reliably disconnected voltage can cause hazardous conditions or damages. - www.e-t-a.de 0/

Power distribution system SVS Application example: jumper instead of circuit protector (e.g. REF-S0) If the power distribution system is not completely fitted with circuit breakers, the subsequently open signal way can be closed with the plugged-in jumper type SB-S-P-0--A. The signal way of the group signalisation goes - after supply of the +DC V potential in X, Si - via the plugged-in juimper and - via all aux. N/O contacts Si () / Si () of the used circuit protector types REF-S0, - back to the signal output of the group signal X, Si In the OK condition (i.e. all circuit protectors plugged in and operating) the signal way X, Si to X, Si is closed.
