Power Connection - Raymarine SR6 Installation Manual

3.5 Power connection

The SR6 can be connected to a DC power supply of 12 or 24 V.
There is no power switch on the SR6 Sirius weather receiver, it
automatically turns on when the system is powered.
The power connection for your system should be made at either the
output of the battery isolator switch, or at a DC power distribution
panel. The power must be fed directly to the system through its own
dedicated cable system and MUST be protected by a thermal circuit
breaker or fuse, installed close to the power connection.
A 2 m (6.6 ft) cable is hard-wired into the SR6 receiver for
connection as follows:
1 Red 12/24 V Battery +ve
2 Black 0 V Battery -ve
3 Drain / ground
This cable may be extended to a distance of 20 m (60 ft) using
suitable wire, gauge AWG 12 or greater.
Grounding requirements
These grounding requirements are applicable for Raymarine
equipment supplied with a separate drain wire or screen.
• The product power cable drain conductor (screen) must be
connected to a common ground point.
• It is recommended that the common ground point is a bonded
ground, i.e. with the ground point connected to battery negative,
and situated as close as possible to the battery negative terminal.
Cables and connections
If a bonded ground system is not possible, a non-bonded RF
ground may be used.
