DC Defender Installation (1101-1027-2)


Setting up a DC Defender for a G1 Base Node requires gathering, at a minimum, the following:


  • Panduit CT-2600 and Crimpmaster ratchet crimp tools or equivalent

  • Soldering iron & wires

  • Wire insulation stripper

  • Torque driver (10-45 in-lbf)


  • 1 DC Defender 1101-1027-2

  • Pole mounting kit 1000-1702

  • 1 Harting terminated DC cable for the Tarana node side of the DC Defender installation PN 33-0004-XXX (where XXX = length in meters)

  • 1 DC cable for the power source side of the DC Defender installation (not included)

    • 9 AWG (or larger) stranded (7x24) tinned copper conductors, PVC insulation, Beldfoil® shield (100% coverage), drain wire, water-blocking tape, PVC jacket

  • 2 terminal ferrules (not included)

    • Panduit FSD82-12-D or equivalent

  • 1 terminal ring (not included)

    • Panduit P18-6R-C or equivalent

  • Drain wire attachment

DC Cable Assembly

This cable assembly will be performed on the ends of 2 DC cables - one connecting to the Tarana node, and the other connecting to the DC power source.

  1. Strip the DC cable insulation to 1.4”. The drain, red, and black wires will be exposed.

  2. Cut the red wire to 1” from the cable jacket.

  3. Strip the insulation back 1/2” from the ends.

  4. Insert the red wire conductor into the terminal ferrule. Use crimp tool to crimp the terminal ferrule onto the wire.

  5. Repeat steps 2 through 4 for the black wire.

  6. Insert the drain wire into the terminal ring. Use crimp tool to crimp the terminal ring onto the drain wire.

DC Defender DCOD 48-5 Assembly

The complete DC Defender DCOD 48-5 assembly with cover removed is shown below.

The DC input conduit accepts 0.450” – 0.705”.

The DC output conduit accepts 0.210” – 0.334”


The left two terminal lugs should be connected to the DC power source. The right two terminal lugs should be connected to the Tarana node. Positive polarity on the pairs of terminal lugs is located on the left. Both DC cable assembly wires should be routed through the strain relief at the cable openings. The enclosure features a built-in cable retention that grips the cable with a screw down bracket.


The unit must be grounded for the suppressor to operate properly.

  1. Remove the cover by loosening the four captive cover screws using a Philips head screwdriver and lift off the cover.

  2. Wiring the suppressor: Thread the power cable from the power source to the strain relief adjacent to the power connector marked “input”. Strip the cable jacket as needed. 

    Strip the power conductors 0.4” (10mm) and connect the DC input +/- terminals. 

    Thread the power cable to the load through the strain relief adjacent to the power connector marked “output”.

    Strip back the cable jacket as needed. Strip the power conductors 0.4” (10mm) and connect the DC input +/- terminals. 

    Tighten both connectors to 10 in-lb and tighter the strain relief to 5 in-lb.

  3. Wiring the remote contacts: Each DCOD is capable of remote annunciation. The annunciation is a form c relay contact set capable of up to 2 Amps. The remote annunciation connector accepts #16 to #30 AWG wire and connections for “Common”, “Normally Open”, and “Normally Closed”. Wiring may be part of the multi-conductor power cable or a separate cable (customer to drill hole and install water-tight conduit fitting).

  4. Grounding: Connect the external ground lug on the enclosure to a solid Earth Ground.

DC Defender DCOD 48-5 Installation

The DC Defender is intended to be installed indoors or outdoors, on wall or pole mount applications. The unit features mounting feet on the sides that mount on 4” center-to-center holes with #10 sized hardware. The mount foot also adapts to 4” diameter pole mounting kits with 4.5” center-to-center holes and larger hardware. 

Install the DC Defender as close to the Tarana Base Node as possible using the provided hardware and the concealed mounting holes. Mount the unit in the orientation shown, with the “UP” marking on the lid facing upward and the cable strain-reliefs facing downward. A pole mounter adapter is available: 1000-1702

Pole Mount

The mounting kit (1000-1702) supports pole diameters ranging from 4” to 10” and includes a pole clamp, mounting bracket, and 2 screws.

  1. Attach the mounting bracket to the back of the DC Defender using screws provided (2x 6-32 x 3/8). Torque to 8-10 in-lbf.

  2. Slide the pole clamp or banding through the slots on the bracket.

  3. Tighten per industry standard.
