To connect a DC source, with the power disabled on the DC supply, connect proper gauge wiring to the
DC supply. For most (short) power cable runs, 18AWG or 24AWG wire can be typically used. Strip the
ends just long enough for enclosure to the DC radio connector (approximately 0.25 inches/6mm). If
using stranded wire, the stripped ends inserted into the DC terminal connector must be solder-tipped. If
using solid wire, a solder tip is not necessary. Ensure that the power wiring is long enough to neatly
traverse, when properly dressed, between the source supply and the radio mounting location. If DC
wires are to be exposed to outdoor environments, use wire in the proper weatherproof wiring jacket.
For longer runs of DC wiring, use a higher gauge wire and/or higher current source supply to overcome
the additional resistance of the DC wiring. However, the DC connector for the radio may not be able to
accept a high diameter wire, transition to thinner gauge near the end of the wiring run or use the
maximum diameter wire for the entire wiring run, as long as it meets the powering requirements
considering total resistance of the wiring and the power source current load capacity.
Insert the wiring ends into the DC mating connector (supplied) and tighten the terminal screws to secure
the wire into the connector. Do not connect the mating connector to the radio system and disable the
power system.
Pay close attention to the polarization of the DC signals coming from the DC supply and the ground
conductor (if any), and ensure that they are connected to the proper pins of the DC mating connector.
The connector mate on the radio is clearly marked on the front panel for proper polarization and for
ground connection.
Wire across the plus (+) and minus (-) terminals from the DC supply. In addition, place a separate
jumper between the proper terminal and the ground terminal to reference one side of the power supply
line to the radio chassis ground. In some cases, the DC system may need to be floating and this ground
jumper is not necessary; however, many configurations require one side to be grounded for proper
electrical safety.

Once the wires are connected to the mating connector, do not connect to the radio. First test the DC
connection to the connector from the DC supply. Engage power on the DC supply, and use a volt meter
to verify proper voltage level and polarity.
Verify that the RF connector is properly terminated, as described in Terminating the RF Connector
.
Disengage power once again on the DC source, and connect the mating connector to the radio device.
Engage power on the DC source. Verify radio is active by observing LED activity. All LEDs flash
during the initial power cycle to verify that they are operational. Secure the DC connector using the
integral captive screws at each end. This prevents accidental disconnection.
Warning! Consult a qualified electrician if uncertain about how to properly ground the
system and connect power.
