2. safety considerations
2.1 The power supply unit is built up in safety class I as well as in accordance with VDE 0411 and VDE
0805/DIN EN 60950. The net transformer is built up after DIN VDE 0551/DIN EN 60742 as safety
separating transformer and is checked with 3.75 kVeff primarily/secondarily. It is 0875th it is equipped
with a VDE checked mains power line with protection leader and may be operated or attached only at
230-V alternating voltage nets with protective earthing therefore radio suppressed in accordance with
VDE.
2.2 It has to be respected on this that the protection leader is interrupted (yellowly/green) neither in the
mains power line nor in the piece of equipment or in the net since with interrupted protection leader
there is serious danger. It has to be respected on this furthermore that the insulation is neither
damaged nor destroyed.
2.3 power supply units don't belong child hands in!
2.4 The accident prevention regulations of the association of the commercial Berufgenosssenschaften
have to be observed for electrical plants and operating supplies in commercial facilities.
2.5 Operating power supply units by trained staff is responsible to supervise to hobby and alone help
workshops in schools, education facilities.
2.6 Open of shutters or remove of parts at this, unless if this is possible by hand, voltage-carrying parts
can be exposed. Junctions also can be voltage-carrying. The piece of equipment must be separated
from all voltage sources in front of a comparison, a maintenance, an overhaul or an exchange of
parts, if a opening the piece of equipment is required. After one, at the open piece of equipment
under tension unavoidably is comparison, a maintenance or a repair, may happen only by a qualified
employee which is familiar with the thus obliged dangers or the appropriate regulations for this this if.
2.7 Condensers in the piece of equipment still can be loaded even if the piece of equipment was
separated from all voltage sources.
2.8 It has to be guaranteed that only safeguardings of Nennstromsträrke said the given type and this one
are used as a substitute. The use of mended safeguardings or bridging of the fuseholder are
inadmissible. The piece of equipment is overtaxing safe and short-circuit protected. There is a grave
fault to Abschmelzen of the initial safeguarding which must be removed by a qualified employee
before the new intact safeguarding can be used by this qualified employee.
2.9 Never switch your power supply unit on immediately, if it is taken to a warm room from a cold, then.
The condensation arising at dewfall can destroy your piece of equipment under unfavorable
circumstances. Let the piece of equipment uneingeschaltet on room temperature come.
2.10 At works with power supply units carrying is forbidden to rings by metallic or conductive jewelry like
chains, bracelets, or the like.
2.11 Power supply units aren't allowed for the application at people or animals.
2.12 Critical tensions (> 35 VDC) are caused at the series connection of the exits of one or several power
supply units.
2.13 Ventilation slits of power supply units may not be covered! The pieces of equipment have to be
moved to hard, heavily inflammable documents so that the air can unhinderedly enter the pieces of
equipment. The cooling of the pieces of equipment is made by forced ventilation.
2.14 Power supply units and the attached consumers may not be operated for unbeaufsichtigt. It is
(measures z to the protection and the safeguarding of the attached consumers opposite effects of the
power supply units. B. overloads, failure of the power supply unit) and meet effects and going out
dangers (e.g. inadmissibly high current consumption) of the consumers this one.
Respect! Sensitive consumers must in addition be protected from destruction by external
measures!
2.15 In the fault case power supply units can give V direct voltage to tensions over 50 of which dangers
start out, also then if the given output voltages of the pieces of equipment lie more lowly.
2.16 At works under tension tool only allowed particularly for this may be used.
2.17 (the exits of the power supply units/and lines attached to this must be protected from direct touch
output jacks-stick). The used lines must have a sufficient isolation or tension strength and be touch
sure the contact points (safety sockets) to this.
2.18 Transferring metallicly shiny lines and contacts has to be avoided. All these places have to be
covered by suitable, heavily inflammable insulants or other measures and protected which from direct
touch. The electrically leading parts of the attached consumers also have to be protected from direct
