3.
Identify the polarity (negative and positive) of the two DC power feed wires. Polarity of
power feed wires are typically color-coded, where red is positive (RTN) and black is
negative (-48VDC).
4.
Insert the exposed wire of one of the two DC-input power source wires into the correct
opening (according to polarity) on the terminal block plug (supplied), as shown in the
following figure. Make sure that only wire with insulation exits the terminal block.
5.
Using a Philips or flat-head screwdriver, tighten the captive screw located above the
installed wire lead to secure the wire to the terminal block.
6.
Repeat steps 1 through 5 for the second wire.

7.
Make sure that no wire strands are left outside the connector and that all strands have
been clamped under the terminal block screw.
8.
Gently try and pull the wires from the terminal block. Only if the wires remain secured to
the terminal block may you continue to the next step; otherwise, if the wires become free,
repeat Step 5 to secure the wires to the terminal block.
9.
Insert the DC terminal block plug into the DC inlet of the Power Supply module located on
the device's rear panel. The following figure shows the completed wiring of the terminal
block.
