DC Power Cable Specifications for the MX2010 Router

The cable lugs attach to the terminal studs of each PDM (see Figure 1).


The MX2010 supports 4-AWG DC power cable lugs for 80-A input and for 60-A input.

Before you install the router, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router.


The router is installed in restricted access location. It has a separate protective earthing terminal (Metric [–M6] and English [–¼-20] screw ground lugs) provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earth terminal must be permanently connected to earth.

Table 1 summarizes the specifications for the DC power cables, which you must supply.

Cable Type

Quantity and Specification


Eighteen pairs of 4-AWG (21.2 mm2), used with 60-A or 80-A PDM. Minimum 75°C wire, or as required by the local code.

You can select 60-A or 80-A input feed capacity on the DC PDM by setting the DIP switch on the PDM to the rated amperage of the DC power input feeds.


You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each PDM.
