Direct DC Power Cable Installation
Depending on the model, the Kona Macro Gateway direct DC feed may terminate at a
dedicated two pin circular plastic connector (CPC) or at a hybrid three pin DC with optical
connector. The direct DC power input is isolated from chassis (earth) with the exception of the
primary surge suppressors. One lead of the DC power feed is normally earth referenced
external to the Kona Macro Gateway (usually at the power source by convention).
The DC power cable shall be rated for outdoor application according to local and national
electrical codes.
The CPC direct DC connector shall be as specified in Table 2 and shall follow the signal polarity
identified in Figure 7.
Figure 7: Direct DC Power CPC Connector Connection Polarity
The hybrid direct DC power connector shall be as specified in Table 2 and shall follow the signal
polarity identified in Figure 8. Although this connector supports a third wire for a ground
connection, this ground is supplementary and does not replace the principle ground wire
terminated at the two-hole lug chassis ground point.
