• 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.

• ABYC A-31 Battery chargers and Inverters
• ABYC TE-4 Lightning Protection
Warning: Product grounding
Before applying power to this product, ensure it has been correctly grounded, in
accordance with the instructions provided.
Warning: Positive ground systems
Do not connect this unit to a system which has positive grounding.
4.4 Cable ferrite installation
Your product is supplied with a suppression ferrite clamp. To ensure EMC Compliance, the supplied
ferrite must be fitted to the cable according to the following instructions.
1. The ferrite must be fitted to the end of the SeaTalkng ™ spur cable closest to the device.
2. The ferrite must be fitted at the distance specified in the illustration above.
3. Ensure a tight and secure fit so that the ferrite will not move up or down the cable.
