amplifiers (LV102 or LV103) will then be used to supply these areas
with current.
The additional LV102s/LV103s receive the control signals from the
terminals C and D of the LZV200. Each LV102/LV103 has to be
connected to its own transformer TR150. The number of amplifier-
transformer-units needed depends on the overall power consumption
of your model railway.
It is absolutely necessary that the electric circuits of all amplifiers are
of the same polarity. Thus, terminal J of one and terminal J of the next
amplifier must be connected to the same side of the track in question.
Otherwise short-circuits will occur when driving over sectioning points.
