Raymarine Evolution EV-1, Installation Instructions Manual

Page: 64 / 142

1. Waterproof fuse holder with 5 A inline fuse must be fitted (not supplied).
2. SeaTalkng ® power cable.
3. Drain wire connection point.
Battery connection scenario A:
Suitable for a vessel with a common RF ground point. In this scenario, the power cable’s drain wire
should be connected to the vessel’s common RF ground point.
Battery connection scenario B:
Suitable for a vessel without a common RF ground point. In this scenario the power cable’s drain wire
should be connected directly to the battery’s negative terminal.
SeaTalkng ® Power cable extension
If you need to extend the length of the SeaTalkng ® power cable, ensure you use suitably rated cable
and that sufficient power is available at the SeaTalkng ® backbone’s power connection point:
• For power cable extensions, a minimum wire gauge of 16 AWG (1.31 mm 2 ) is recommended. For
cable runs longer than 15 meters, you may need to consider a thicker wire gauge (e.g. 14 AWG
(2.08 mm
2
), or 12 AWG (3.31 mm
2
) ).
• An important requirement for all lengths of power cable (including any extension) is to ensure that
there is a continuous minimum voltage at the product’s power connector of 10.8 V dc, with a
fully flat battery at 11 V dc.
Important:
Be aware that some products in your system (such as sonar modules) can create voltage peaks at
certain times, which may impact the voltage available to other products during the peaks.
