Wiring guidelines
The following table lists copper wire sizes and maximum lengths allowable
between the AXB-FBM and the Master Controller's power supply. When
these distances are exceeded, a separate, optional 12 VDC power supply
is used to power the AXB-FBM. The maximum wiring lengths are based
on 12 VDC available at the Master Controller's power supply output.
Wiring AXlink and Auxiliary 12 VDC Power
Figure 3 diagrams wiring the AXlink and a 12 VDC auxiliary power supply
to the AXB-FBM.
Use the 12 VDC power supply when the distance between the Master
Controller and AXB-FBM exceeds the limits described in Figure 3. Make
sure to connect only the GND wire on the AXlink connector when using a
12 VDC power supply. Do not connect the PWR wire to the AXlink
connector's PWR opening.
