Installation
General mounting guidelines
Warning: Do not install the unit in a hazardous/flammable atmosphere.
Ú
Note: Choose a mounting location that will not expose the unit to conditions that
exceed the technical specifications.
Mounting location
Ensure that the selected area allows for:
• Cable routing, cable connection and cable support.
• Connection and use of portable storage devices.
• Viewing any LED indicators.
• Easy access to serviceable parts.
Do also consider:
• The free space around the unit to allow for adequate cooling.
• The mounting surface’s structure and strength, with regard to the weight of the
equipment.
• Any mounting surface vibration that might damage the equipment.
• Hidden electrical wires that might be damaged when drilling holes.
Ventilation
Inadequate ventilation and subsequent overheating of the unit will cause unreliable
operation and reduced service life.
Ventilation behind units is recommended for all units which are not bracket mounted.
Examples of enclosure ventilation options, in order of preference, are:
• Positive pressure air from the vessel's air conditioning system.
• Positive pressure air from local cooling fans (fan required at input, fan optional at outlet).
• Passive airflow from air vents.
Electrical and radio frequency interference
This unit conforms to the appropriate Electromagnetic Compatibility (EMC) regulations. To
ensure that the EMC performance is not compromised, the following guidelines apply:
• Separate battery used for the vessel engine.
• Minimum 1 m (3 ft) between the device, the device's cables and any transmitting
equipment or cables with radio signals.
• Minimum 2 m (7 ft) between the device, the device's cables and the SSB radio.
• More than 2 m (7 ft) between the device, the device's cables and the radar beam.
WiFi
It is important to test the WiFi performance before the location of the unit is decided.
Construction material (steel, aluminum, or carbon) and heavy structure might affect WiFi
performance.
The following guidelines apply:
• Select a location where there is a clear, direct line of sight between WiFi connected units.
• Keep the distance between WiFi units as short as possible.
• Mount the WiFi unit at least 1 m (3 ft) away from:
-
Other WiFi enabled products.
- Products that send wireless signals in the same frequency range.
- Equipment that might generate interference.
