• This transformer is designed exclusively to be used
indoors.
• Mount the transformer on a sturdy base. Never operate
the transformer on a base that is wet or that is readily
flammable.
• This transformer is not a toy. It is designed for the control
of a model railroad layout.
• The transformer must be unplugged from the electrical
outlet before being moved. If the transformer has been in
operation, let it cool off before moving it.
• Inspect the condition of the power cord and the transfor-
mer housing at regular intervals for damage. This visual
inspection should only be done when the power cords
for all of the transformers being used are unplugged from
the household current. If you have the least suspicion
that the transformer is damaged, you should not use it
again until it has been thoroughly inspected and repaired
by an authorized service organization (example: Märklin
Service Department).The power cord for the transformer
must never be replaced. In this instance dispose of the
transformer in an authorized manner, or send it to the
Märklin Service Department for exchange.
The following safety precautions must always be
observed when connecting more than one transformer
to a model railroad layout or setup:
• The power cords for all existing transformers connected
to the layout must first be unplugged when connecting
electrical power consumers (examples: feeder connec-
tions, turnouts, signals, lights, etc.) to a transformer!
• The alternating current outputs of two or more transfor-
mers must never be connected with one another.

Important Safety Risk!
Under adverse conditions it is highly dange-
rous, if the yellow or red sockets/terminals for
two or more transformers are connected with each other
in addition to the connections between the brown ground
sockets/terminals. In such a situation if the power cord for
