FLIR M100SERIES Nstallation & Operation Instructions page 41

Important: When planning and wiring, take into consideration other products in
your system, some of which (e.g. sonar modules) may place large power demand
peaks on the vessel's electrical system.
Note: The information provided below is for guidance only, to help protect your
product. It covers common vessel power arrangements, but does NOT cover every
scenario. If you are unsure how to provide the correct level of protection, please
consult an authorized FLIR dealer or a suitably qualified professional marine electrician.
Implementation — direct connection to battery
• The power cable supplied with your product may be connected directly to the vessel's
battery, via a suitably rated fuse or breaker.
• The power cable supplied with your product may NOT include a separate drain wire.
If this is the case, only the power cable's red and black wires need to be connected.
• If the supplied power cable is NOT fitted with an inline fuse, you MUST fit a suitably
rated fuse or breaker between the red wire and the battery's positive terminal.
• Refer to the inline fuse ratings provided in the product's documentation.
• If you need to extend the length of the power cable supplied with your product,
ensure you observe the dedicated Power cable extensions advice provided in the
product's documentation.
A Battery connection scenario A: suitable for a vessel with a common RF ground
point. In this scenario, if your product's power cable is supplied with a separate
drain wire then it should be connected to the vessel's common ground point.
B Battery connection scenario B: suitable for a vessel without a common grounding
point. In this case, if your product's power cable is supplied with a separate
drain wire then it should be connected directly to the battery's negative terminal.
