Installing the Hardware
Internally, the X-Pedition 8600 DC power supply consists of two separate power supplies. Each of
these internal power supplies must be energized to produce sufficient power for the
X-Pedition 8600 to operate. Each internal power supply is connected to source power through a
pair of positive (+) and negative (-) wiring lugs on the wiring block.
Figure 27 shows the internal
relationship of the wiring lugs of the X-Pedition 8600 DC power supply.

Note: For the X-Pedition 8600 to work properly, both positive (+) terminals and both negative (-)
terminals of the X-Pedition 8600 DC power supply MUST be connected to the DC source.
Because of the X-Pedition 8600 DC supply current requirements, each pole of the 48 Volt DC
source should use 6 gauge wire. Each 6 gauge wire can be divided into two 12 gauge wires by using
a conductive splitter-block. This creates two 12 gauge wires carrying positive (+) current and two
12 gauge wires carrying negative current. In turn, both 12 gauge positive (+) wires and both 12
