- has been subjected to any serious transport-
related stresses.
• Please handle the product carefully. Jolts, im-
pacts or a fall even from a low height can damage
the product.
• Also observe the safety and operating instruc-
tions of any other devices which are connected
to the product..
• The product should not be used immediately after
it has been brought from an area of cold tempera-
ture to an area of warm temperature. Condensed
water might destroy the product. Wait until the
product adapts to the new ambient temperature
before use.
• Make sure that the output of the power adapter is
not short-circuited.
• Never pour liquids over electrical appliances and
never leave objects filled with liquids (e.g. vases)
on it or in the vicinity. There is a high risk of fire or
life-threatening electric shock.
• Always lay the cables so that nobody can trip over
or become entangled in them. This poses a risk
of injury.
• When setting up the product, make sure that the
cable is not pinched, kinked or damaged by sharp
edges.
• The plug must be pulled out of the socket under
the following conditions:
- before cleaning the product
- during a thunder storm
- if the product is not being used over a long
period.
b) Miscellaneous
• Consult an expert when in doubt about operation,
safety or connection of the device.
•
Maintenance, modifications and repairs are to be
performed exclusively by an expert or at a quali-
fied shop.
• If you are not sure about the correct connection
or use, or if questions arise which are not cov-
ered by these operating instructions, please do
not hesitate to contact our technical support or
another qualified specialist.
Operation
Ensure the polarity is correct when
establishing a connection. The posi-
tive terminal of the cable is identified
by a white line and a sticker showing
a +.
Ensure the power supply unit’s open
ends are insulated with suitable in-
sulating material at all times. This
applies to the power supply unit
whether it is installed or not.
Always unplug the power plug first
before disconnecting the connectors
from the consumer.
1. LEDs and LED strips already feature soldering
points where the power supply unit’s open ends
can be attached. Ensure the polarity is correct.
After assembly, insulate the connections with
suitable insulating material such as heat shrink
tubing.
2.
Set the required voltage (3 / 4.5 / 5 / 6 / 7.5 / 9 /
12 V/DC) with the key.
3.
Connect the mains plug to a standard mains
socket (100 – 240 V/AC, 50/60 Hz).
4.
Remove the power adapter from the mains when
it is no longer in use.
Cleaning
• When cleaning, the power adapter must be dis-
connected from mains socket.
• Only use dry and soft cloth to clear the housing of
the power adapter.
• Do not use abrasive or solvents.
Disposal
Electronic devices are recyclable
waste and must not be disposed of in
the household waste. At the end of its
service life, dispose of the product in
accordance with applicable regulatory
guidelines.
