Marco,
I recommend that you attach the wires to the 5 volt converter and use heatshrink or electrical tape to insulate the contacts. What others are telling you is this... Do not plug in the power cable to the DAP-1522 until you have applied power to the PD and checked the polarity of your connections. Use a known good meter with the probes in the correct inputs on the meter. Make sure that polarity of the voltage matches that printed on the radio. A great check is to note the polarity with your meter prior to cutting the connector off the power supply that comes with the radio. What many teams do, is using another connector pair (i.e. Anderson Power Plugs or any other two conductor insulated plug/jack.) is add a connector to the output of the 5 volt regulator and the output of supplied power supply that matches that of the radio cable. It is then possible to use either the robot supply or the wall supply to feed the radio.
