Mounting
Open the locomotive housing according to the manufacturer's instruc-
tions. Determine the location where you want to install the decoder.
First disconnect the connections of the motor and the consumers
from the rail collectors or, for locomotives with electronic or electro-
mechanical switch, the connections of the switch to the motor and to
the rail collectors. The changeover switch is no longer needed and
should be removed.
Note: When installing the decoder, the already existing wiring in the
loco can be used in most cases. The existing wires have to be unsol-
dered or separated at the appropriate places and have to be soldered
to the corresponding solder pads of the decoder.
