Wiring
Note: The con-
densers C2 and C3
must be removed!
The motor must not
have any ground
connection (to the
locomotive frame)
by means of radio / television interference suppression
components!
1. Connect the red and brown power wires (track).
2. Connect the headlights (gray wire at the front, yellow
wire at the rear). Connect the ground wire (orange) only
if the headlights are not grounded through the locomotive
frame.
3. Connect the motor wires (green and blue). Do not forget
the chokes at the motor connections!
4. Change the green and blue wire connections if necessary
so that the locomotive‘s direction of travel agrees with the
headlights that are on for a given setting.
The orange wire must never be connected to the brown wire!
