5. Cabling the Device
To connect device to DC power:
1.
Disconnect your DC wires from your DC power source.
2.
Using a wire-stripping tool, strip the ends of the two wires (6-AWG) to a length that is
sufficient for inserting into the supplied terminal block. Make sure that you do not strip too
much of the insulation so that wire is not exposed when it exits the terminal block plug
after it has been secured to the terminal block.
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 figure.
Make sure that only wire with insulation exits the terminal block. 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. Repeat steps 1 through 5 for the second wire.
2.
Make sure that no wire strands are left outside the connector and that all strands have been
clamped under the terminal block screw.
3.
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.
4.
Insert the DC terminal block plug into the DC inlet located on the device's rear panel.
