Connection procedure
Connect the power cable part of the digital cable to either a 12 V or 24 V dc supply, as follows:
1. Red wire to the ve, either at the output of the battery isolator switch or at a dc distribution
panel.
2. Black wire to battery negative.
3. Drain connection (screen) to the common ground point (see
Grounding

Sharing a breaker
Where more than 1 piece of equipment shares a breaker you must provide protection for the
individual circuits. E.g. by connecting an in-line fuse for each power circuit.
1 Positive (+) bar
2 Negative (-) bar
3 Circuit breaker
4 Fuse
Where possible, connect individual items of equipment to individual circuit breakers. Where this is
not possible, use individual in-line fuses to provide the necessary protection.
9.3 Connecting
When connecting your HD Digital Radome Antenna, use the instructions given here and also refer to
the installation instructions for the multi-function display (MFD) to which you are connecting.
Run the digital cable from the HD Digital Radome Antenna to the signal and power connection points:
• Run the signal connector to the appropriate MFD.
• Run the power cable to a suitable 12 V or 24 V connection point on the boat’s power system. We
recommend connection is made at the boats power distribution panel, wherever possible.
