Selecting A Location; General Location Requirements; Emc Installation Guidelines - Raymarine axiom 7 Installation Instructions Manual

3.1 Selecting a location

Caution: Mounting surface requirements
This product is heavy. To prevent potential damage to the product and / or your
vessel, observe the following BEFORE installing the product:
• Refer to the weight information provided in the technical specification for this
product and ensure that the intended mounting surface is suitable for bearing
the weight.
• If the mounting surface is not suitable for the product weight, you may need to
reinforce the mounting surface.
• If in doubt, refer to a professional marine equipment installer for further
guidance.
Warning: Switch off power supply
Ensure the vessel's power supply is switched OFF before starting to install this
product. Do NOT connect or disconnect equipment with the power switched
on, unless instructed in this document.
Warning: Potential ignition source
This product is NOT approved for use in hazardous/flammable atmospheres. Do
NOT install in a hazardous/flammable atmosphere (such as in an engine room
or near fuel tanks).

General location requirements

When selecting a location for your product it is important to consider a number of factors.
Key factors which can affect product performance are:
• Ventilation — To ensure adequate airflow:
– Ensure that product is mounted in a compartment of suitable size.
– Ensure that ventilation holes are not obstructed. Allow adequate separation of all equipment.
Any specific requirements for each system component are provided later in this chapter.
• Mounting surface — Ensure product is adequately supported on a secure surface. Do not mount
units or cut holes in places which may damage the structure of the vessel.
• Cabling — Ensure the product is mounted in a location which allows proper routing, support
and connection of cables:
– Minimum bend radius of 100 mm (3.94 in) unless otherwise stated.
– Use cable clips to prevent stress on connectors.
– If your installation requires multiple ferrites to be added to a cable then additional cable clips
should be used to ensure the extra weight of the cable is supported.
• Water ingress — The product is suitable for mounting both above and below decks. Although
the unit is waterproof, it is good practice to locate it in a protected area away from prolonged and
direct exposure to rain and salt spray.
• Electrical interference — Select a location that is far enough away from devices that may cause
interference, such as motors, generators and radio transmitters / receivers.
• Power supply — Select a location that is as close as possible to the vessel's DC power source.
This will help to keep cable runs to a minimum.

EMC installation guidelines

Raymarine equipment and accessories conform to the appropriate Electromagnetic Compatibility
(EMC) regulations, to minimize electromagnetic interference between equipment and minimize the
effect such interference could have on the performance of your system
Correct installation is required to ensure that EMC performance is not compromised.
