Safety Notes - T+A DD 1230 R Operating Instructions Manual

All the components we use meet the currently valid Ger-
man and European safety norms and standards.
Our production areas are supervised by highly qualified
expert staff, and all final production units are checked
comprehensively by a fully automated, computer-
controlled system to ensure uniformly high quality. We
guarantee that our products meet our own specifications
to the full.
Please read right through these operating instructions
carefully before you attempt to use your new equipment.
Note in particular the information regarding setting up
and operating the equipment, and the safety notes.
The unit must be set up in such a way that none of the
connections can be touched directly (especially by chil-
dren). Be sure to read the information in the section
entitled 'Installation and wiring'.
The power supply required for this decoder is printed on
the mains supply socket. The unit must never be con-
nected to a power supply which does not meet this
specification. If the unit is not to be used for a long pe-
riod, disconnect it from the mains supply at the wall
socket.
Mains leads must be deployed in such a way that there is
no danger of damage to them (e.g. through persons
treading on them or from furniture). Take particular care
with plugs, distribution panels and connections at the
decoder.
Liquid or foreign bodies must never be allowed inside the
cooling slots. Protect the unit from drips and splashes of
water; never place flower vases or fluid containers on the
unit.Mains voltage is present inside the unit, and there is
a risk of lethal electric shock. Do not exert undue force
on the mains connectors.
Caution!
The mains button is not a mains isolation switch.
Even when the green LED is not glowing, parts of the
machine remain connected to the mains power sup-
ply. If the decoder is not to be used for a long period,
we recommend that you isolate it from the mains by
pulling out the mains plug at the wall socket.

Safety notes

This device should never be used without proper super-
vision. The decoder should be set up well out of the
reach of small children. This applies to all electrical
equipment.
The unit should only ever be opened by a qualified spe-
cialist technician. Repairs and fuse replacements should
be entrusted to an authorised
With the exception of the connections and procedures
described in these instructions, no work of any kind may
be carried out on the decoder by unqualified persons.
If the unit is damaged, or if you suspect that it is not
functioning correctly, immediately disconnect the mains
plug at the wall socket, and ask an authorised
cialist workshop to check it.
The unit may be damaged by excess voltage in the
power supply, the cable network or in aerial systems, as
may occur during thunderstorms (lightning strikes) or due
to static discharges.
Special power supply units and excess voltage protec-
tors such as the
panel offer some degree of protection from damage to
equipment due to the hazards described above.
However, if you require absolute security from damage
due to excess voltage, the only solution is to disconnect
the unit from the mains power supply and any aerial
systems.
If you believe there is a danger of excess voltage (e.g.
when an electrical storm is building up) disconnect the
unit from the mains and the aerial socket.
All mains power supply and aerial systems to which the
unit is connected must meet the currently valid regula-
tions, and must be installed by an approved electrical
installer.
Note:
Many insurance companies offer lightning damage in-
surance for electrical equipment as part of their house-
hold insurance service.
