Timed DC/DC transducer, which one are the calculated battery tension of 12 V (e.g. car starter battery) into a direct

(the equipment is thought for the wall cultivation mounting position see connection figure). With the mode under full load a
dissipation power of approx. 30 results for W which one must be had a laxative effect as warmth. Therefore they take care
at the mounting that sufficient cooling air can stream by the equipment. At unfavourable mounting position, however, the
equipment is protected by a thermoswitch from overheating which then fells output voltage on the value of the input
voltage. Cannot to prevent an unfavourable mounting position you please don't take the full performance.
Because of the high current intensities at battery equipments should to-and derivations are lent to short and sufficient

2. Safety notes general
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. 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-main 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 Berufgenosssen schaften 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 stromstraerke 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.
