Important:
Be aware that the suitable fuse rating for the thermal breaker or fuse is dependent on the number
of devices you are connecting.
Power cable extension
If you need to extend the length of the power cable supplied with your product, ensure you observe
the following advice:
• The power cable for each unit in your system should be run as a separate, single length of 2-wire
cable from the unit to the vessel's battery or distribution panel.
• For power cable extensions, a minimum wire gauge of 16 AWG (1.31 mm
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
• 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.
Grounding
Ensure that you observe any separate grounding advice provided in the product's documentation.
