1. INSTALLATION
You can install the antenna unit as follows. See the outline drawings at the back of this
manual.
• Platform mount, fixed from bottom (section 1.2)
• Pole mount (section 1.3)
• Roof mount, fixed from top (section 1.4)
• Antenna Base mount (section 1.5, option)
Use the NMEA 2000 Antenna cable (FRU-NMEA-PMMFF-060) for installation.
1.1 Installation Considerations
When selecting a mounting location, keep in mind the following points:
• Keep the length of the antenna cable in mind when selecting a mounting location.
• Make sure the mounting location is strong enough to support the weight of the unit.
See the outline drawings at the back of the manual.
• Leave enough space around the unit for service and maintenance. See the outline
drawings at the back of this manual for minimum service clearance.
• The sensor should be separated more than three meters from Inmarsat F/FB anten-
nas. Select a location outside this transmission area.
• Do not bundle the antenna cable with radio equipment cables. When these noise
reductions are insufficient, adjust the squelch on the radio equipment.
• Select a location with no obstructions to the radio waves.
• Select a location with no local vibration or impact (including vibrations generated by
an engine or the mounting mast for this equipment) for the GPS sensor in the an-
tenna unit.
• Observe the compass safe distances (see page iii) to prevent interference to a mag-
netic compass.
How to select the installation site
The installation site must satisfy the conditions described in the antenna installation
procedure at the back of this manual (Dwg. No. C7286-Y01-*).
NOTICE
Do not apply paint, anti-corrosive sealant or contact
spray to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage
coating and plastic parts, especially plastic connectors.
