W&T offers interface accessories such as Com-Servers and
Web-IOs, plug-in power supplies with various output voltages
and power ratings, all of which are described in this guide
along with their properties and technical data.
Compared with DIN rail power supplies, plug-in versions offer
the advantage of simple installation which can be accomplished by non-specialists.
Current information can be found in the Internet at
http://www.wut.de or in the e-mail updates provided to
members of the W&T Interface Club. Subscriptions to the
Interface Club can requested from the W&T homepage.

General characteristics and safety advisory
All the power supplies described in this guide feature either
a CE mark or UL approval, depending on the primary plug, so
that the appropriate power supplies for anywhere in the world
can be selected.
The power supplies are compatible with all W&T devices and
have an operating temperature range of 0°C …+40°C to cover
office or small business applications.
Safety Advisory: HAZARDOUS VOLTAGE
The following advisory must be read and understood
before installing the power supplies. Non-observance
of this advisory may have serious or fatal consequences.
Protection for operating personnel and the equipment is
only ensured if the power supply is used as specified. Any
use other than described in this Manual will compromise the
safety and function of the power supply and any connected
systems.
If faults cannot be remedied, take the power supply out of
service and guard it against unintentional startup. Tampering
with and modifying the power supplies is hazardous and is
therefore not permitted.
I
Note the following points for use:
• Do not permit ambient temperatures which exceed the
range of 0°C to +40°C.
• Do not use the power supply if there is visible damage to
the housing or cable.

W&T Plug-in Power Supplies 5V / 24V DC
• Never plug a primary adapter into the socket separate
from the power supply. Otherwise there is the risk of
electrical shock.
• The power supply should never be installed in areas
which are subject to moisture or condensation, unusual
environmental conditions, continuous vibration or strong
temperature fluctuations, and do not use outdoors.
• Disconnect the power supply from the mains when
thunderstorms are present or when it will not be used for
longer periods of time.
• Do not pull on the cable to disconnect the power supply
from the mains.
• The power supply is maintenance-free. Do not open it.
Otherwise there is the risk of electrical shock.
• No modifications to the power supply are permitted.
• Any repair must be performed by authorised specialists
only.
• Before cleaning disconnect the plug-in power supply from
the mains. Do not use chemical agents for cleaning.
• The power supply may not be disposed of with household
waste, but rather brought to an authorised disposal
facility for electrical and electronic waste.
