Connecting the Power Supply

The nominal input voltage for a radio is +13.8 VDC (negative earth) with an input voltage range of +10 to
+30 VDC. The maximum power input is 30 W.
The power connector required is a Phoenix Contact 4 pin female screw fitting part MC 1.5/ 4-STF-3.5. This
connector is supplied fitted to the radio.
The negative supply of the Aprisa SR power connection is internally connected to the Aprisa SR enclosure.
Power must be supplied from a Negative Earthed power supply.
Wire your power source to power connector and plug the connector into the radio. The connector screws
can be fastened to secure the connector.
