2. Safety notes
2,1 the power supply unit is in safety class system I as well as in accordance with VDE 0411 and VDE 0805
(EN60950) structured. The supply transformer is structured and with 3,75 kVeff is primarysecondarily checked
according to DIN VDE 0551 as safety insulating transformer. It is radio-screened in accordance with VDE
0875T11 curve B. Es is equipped with a VDE checked main with protective grounding and may therefore only to
230-V- with protective grounding be operated or attached.
2,2 it is to be made certain that protective grounding (yellow/green) is interrupted neither in the main nor in the device
or in the network, since with interrupted protective grounding mortal danger exists. It is to be made certain further
that the isolation is damaged nor destroyed neither.
2,3 power supply units do not belong into child hands!
2,4 in commercial mechanisms is to be considered the rules for the prevention of accidents of the federation of the
commercial for electrical system and resources.
2,5 in schools, training facilities, hobby and self-help workshops. is by hand possible for
2,6 when opening covers or removing from sections, except if this, can live sections be opened. Also interface can be
live. Before an alignment, maintenance, a repair or an exchange of sections the device must be separate from all
voltage supplies, if opening of the device is necessary. If thereafter an alignment, maintenance or a repair at the
opened device under voltage are inevitable, may take place only by means of a specialist, who is familiar with the
associated dangers or the relevant regulations for it.
2,7 condensers in the device can be still loaded, even if the device were separated from all voltage supplies.
2,8 it is to be guaranteed that only protections of the indicated type and the indicated call nominal current are used as
back-up. The use of repaired protections or bridging the fuse holder is illegal. The device is overload-proof and
short-circuit-protected. When burning the input protection through a serious error is therefore present, which must
be eliminated by a specialist, before the new intact protection can be used by this specialist.
2,9 switching it your power supply unit never equivalent if it is brought by a cold into a warm space. The condensation
developing thereby can destroy your device under unfavorable circumstances. Let the device unein switched to
room temperature come. carrying of metallic or conductive decoration is forbidden to
2,10 with work with power supply units such as chains, bracelets, rings or the like.
2,11 power supply units are not certified for application at humans or animals.
2,12 during the series connection of the outputs one or several power supply units is produced lethal voltages (>35
VDC).
2,13 louvers of power supply units may not be taken off! The devices are on hard to place with difficulty inflammable
documents so that air can occur the devices unhindered. The cooling of the devices takes place predominantly
via convection.
2,14 power supply units and the attached consumers may not be operated unsupervised. Measures are to be taken to
the protection and the protection of the attached consumers in relation to effects of the power supply units (e.g.
overvoltages, failure of the power supply unit) and the effects and dangers outgoing from the consumers
themselves (e.g. illegally high power input). Note! Sensitive consumers must be protected additionally by external
measures against destruction!
2,15 in the event of an error can deliver power supply units voltages over 50 V DC voltage, from which dangers
proceed, also then if the indicated output voltages of the devices lower is situated.
2,16 with work under voltage for it expressly certified tools may be only used.
2,17 the outputs of the power supply units (exit hub/clamps) and to it attached lines must be protected against direct
contact. In addition the used lines must sufficient isolation or tension strain possess and the contact points be
contact-voltage-proof (safety sockets).
2,18 shifting metallically bright lines and contacts is to be avoided. All these places are by suitable to take and to
protect thus against direct contact with difficulty inflammable insulants or other measures off. Also the electrically
leading sections of the attached consumers are to be protected by appropriate measures against direct contact.
2,19 if to assume it is that a safe operation is no longer possible, then is the device out of operation to set and against
unintentional operation protect. It is to be assumed that a safe operation is no longer possible, if - the device or the mains
cable visible damages indicates, - the device any longer does not operate, - after longer storage under unfavorable conditions,
- after heavy transport stresses.
