• For power cable extensions, it is recommended that a
minimum wire gauge of 16 AWG (1.31 mm 2 ). 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 of 10.8 V at the
product’s power connector, with a fully flat battery at
11 V.
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.
