4. Twist the copper wire strands together to form a tight braid. If possible,
solder the exposed braid of wire together for better conductivity.
5. Connect the external power feed and power ground/return lines to the DC
plug (provided with the switch) as shown in Figure 13 below. The power
leads are labeled on the rear of the switch, below the DC power connector.
The -48 VDC power feed uses the “-” pin and the ground/return lines the
“+” pin for power sources A and B. Use a small flat-tip screwdriver to loosen
the screws on the power plug and open the wire clamps.
6. Insert the wire leads into the openings shown in the figure below. Each lead
inserted in the power plug must match the lead attached to the power
source. Use the label above the DC power connection block to identify the
appropriate power input and return or ground lines.

7. Push each wire about half an inch into the opening on the plug, and tighten
down the clamp screw securely. You should not be able to pull on the wire
and dislodge it.
