WIRING
Wiring guidelines
Don’t:
• Make sharp bends in the cables.
•
Run cables in a way that allows water to flow down into the connectors.
• Run the data cables adjacent to radar, transmitter, or large/high current carrying cables or
high frequency signal cables.
• Run cables so they interfere with mechanical systems.
• Run cables over sharp edges or burrs.
Do:
• Make drip and service loops.
• Use cable-ties on all cables to keep them secure.
• Solder/crimp and insulate all wiring connections if extending or shortening the cables.
Extending cables should be done with suitable crimp connectors or solder and heat shrink.
Keep joins as high as possible to minimize the possibility of water immersion.
• Leave room adjacent to connectors to ease the plugging and unplugging of cables.
⚠
WARNING: Before starting the installation, turn the electrical power off. If power is left on
or turned on during the installation, fire, electrical shock, or other serious injury may occur.
Be sure that the voltage of the power supply is compatible with the unit.
⚠
WARNING: The positive supply wire (red) should always be connected to (+) DC with a
fuse or a circuit breaker (closest available to fuse rating). For the recommended fuse rating,
refer to the Specifications section of this manual.
