3.1. Power supply
The R043 needs to be powered from a stable 12V to 35V DC power supply. Power(+) and GND(-)
terminals are clearly marked on the side of the terminal block. The R043 has been designed so that it
can be connected to two independent power supplies, PWR and PWR1, if required, to minimize the
chance of failure.
The R043 is equipped with reverse polarity protection to protect the device in case of improper
installation.
Next to PWR1, there is a grounding screw. It’s always recommended to connect a ground cable to this
and link the other end of the cable to the ground on the boat.
