Route The Cables; Route The Power And Data Cables - Humminbird CHIRP Installation Manual

5. Route the Cables

After connecting the power cable and data cable to the Radar scanner unit, you must route the cables to
the control head and power source. Cable routing depends on whether you mount the scanner on a platform
or pole.
CAUTION! Confirm that the vessel's power supply is switched off before proceeding.
CAUTION! Do NOT mount the cables where the connectors could be submerged in water or flooded. If
cables are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the
connectors to prevent corrosion. Dielectric grease can be purchased separately from a general hardware or
automotive store.

1. Route the Power and Data Cables

Route the power cable to the power source and the data cable to the control head or Ethernet Switch location.
You will connect the cables in a later procedure.
1. Confirm the vessel's power supply is switched off.
2. Route the power cable to the fuse panel or battery.
3. Route the data cable to the control head or Ethernet Switch.
4. Secure the cables near the scanner to support the weight of the cables and prevent strain on the watertight
cable seals.
If the cable is to pass through tubing or a bulkhead, protect the unfinished end.
Make a drip loop and apply sealant at the entry point of an exterior bulkhead.
5. Proceed to Connect to Power and Ethernet.
CAUTION! Do not use the unfinished wires or fabric braid to pull the cable.
