Power distribution system SVS14 1

Power distribution system SVS14
Description
The power distribution system SVS14-10 optimises DC 24 V distribution
on the field level in automated process control, industrial production
and chemical plants. The system holds an integral ammeter (display
25 A) for the total current and offers ten ways for electronic and
thermal-magnetic circuit breakers including group signalling. It allows
protection of transformers, actuators, solenoids, peripheral PLCs,
intelligent terminals etc. on the field level. Particularly for systems with
a great number of sensors/actuators the SVS14 power distribution
system enables a space-saving and cost-effective design of protection
control cabinets.
1
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 control.
The SVS14 is a track-mountable system and accommodates 10 electronic
or thermal-magnetic circuit breakers. All terminals (entry line DC +24 V,
GND (-) for self-supply, load outputs L(+) and group signalling are
standard screw terminals.

Mass: SVS14-10-C22-xxx approx. 600 g
The power distribution system must be installed by qualified
personnel only.
l Only after expert installation may the device be connected to
a power supply.
l The device is only suitable for use in safety extra-low voltage
(DC 24 V).
l Connection to higher or not reliable disconnected voltages may
cause perilous conditions or damages.
l The max. total current of the SVS14 system must not be exceeded.
l In each load circuit the cable cross sections und the current rating
of the protective element have to adjusted to the rating of the
connected load.
l The technical data of the circuit breakers used have to be observed.
l According to the “Machinery Directive 2006/42/EG and
the norm EN 60204-1, Machine Safety” special precautions have
to be taken in machinery (e.g. use of a safety PLC) to prevent inadvertent start-up of machinery parts. In the event of a failure (short
circuit/overload) the load circuit will be disconnected by the circuit
breaker.
l After tripping of the circuit breaker and before reset the trip cause
(short circuit or overload) has to be remedied.
l The international standards (e.g. DIN VDE 0100 for Germany) have
to be observed with installation and selection of cables.

If the power distribution system is not completely fitted with
circuit breakers, the open signal way (S2) to (S1) can be closed
with the integral Si switch (per way), Si-switch change over
to close.
In OK condition (i.e. all circuit breakers plugged in and operating)
the signal way (S2) to (S1) is closed.
