6 DataTrack System Planning and Installation Manual
Ground Path
The ground path must be continuous with no interruptions. A ground path can cross itself any number
of times. Continuity is the sole concern in planning a DataTrack ground path.
The following illustrations show examples of ground paths. These drawings are plan views, showing
the DataTrack system as if you were looking at it from above.
Figure 2: Simple ground path system
Figure 3: Advanced ground path system
Note:
There are a variety of configurations that can be assembled using the available
DataTrack couplers. However, couplers only fit into DataTrack in one orientation. The
data connection of the coupler must mate with the data connection of the track. This
is important to keep in mind when choosing couplers (ground left versus ground
right, ground inside versus ground outside).
Note:
These figures show a continuous ground path within the DataTrack system. If any of
the couplers shown in these examples were replaced with an outside ground model,
the ground path would be broken and the DataTrack would not be properly
grounded (and the couplers would not physically fit within the track).
