Installing DC Power Source Wire Leads
These instructions describe how to connect your 3-wire DC power source to the power
connector on your DC power supply. A small flat-tip screwdriver and a wire stripper are
required for this procedure.
1. Prepare the three (3) wires—10 gauge—that will plug into the power supply. First, make
sure they are not plugged into the 48-volt power source.
2. Next, use a wire stripper to carefully strip about a half-inch off the end of each wire,
removing the outer insulation to expose the copper core.
3. Twist the loose strands of copper wire together so that they form a tight braid. If possi-
ble, solder the entire braid of wire together for better conductivity.
4. Open the wire bay door for one of the three (3) power connector holes. The front of the
power connector contains a row of square holes. It also contains three (3) circular holes
(located directly above the square holes) that contain screws; you loosen the screws in
these holes to open the wire bay doors (square holes) on the connector front so that you
can insert the wire leads into the power connector.
a. Insert a small flat-tip screwdriver into one of the three (3) screw holes.
b. Loosen the screw so that the door for the wire bay on the connector front opens.

5. Insert the appropriate wire lead into the open circular hole. The silkscreen above each
hole indicates which power lead—ground (GND), positive (+), or negative (-)—to plug
into which hole. The lead you insert must match the lead attached to the 48-volt power
source (i.e., ground to ground, positive to positive, negative to negative).
♦ Warning ♦
You must plug DC wire leads into the correct holes in
the DC power connector. Use the labels above the DC
power connector as a guide to ground, positive and
negative connections.
If you plug wire leads into the wrong holes, the power
supply will not work and could result in damage.
Push the wire in far enough so that it reaches the back wall of the connector, about a half
inch inside.
Door inside square hole will
open when screw is loosened in
circular hole directly above it.
Loosen Screw.
