4.2. 2-Conductor Track System:
If the manufacturer of your digital command station
permits
a
common layout ground
(“brown” or “J”)
one rail
of the
2-conductor track
has to be
isolated
at the
cross
over joints
from one to the next booster electrical circuit.
If the manufacturer of your digital command station
does not
permit
a
common
layout ground
(
„brown“
)
both rails
have to be
isolated at the cross over joints
.
