Installation Guidelines
This guide outlines the process for installing the
TR400/OC400 Terminal.
This kit must not be used with any other device.
• Only qualied personnel should install this
communication equipment.
• Ensure that the units are protected from
dirt and moisture.
• Select an area to mount components where
there is no interference from other objects.
• Ensure that each mounting surface is strong
enough to support the component being
mounted to prevent the component from
loosening over time.
• Mount all components securely to prevent
shifting that could cause injury or could
interfere with safe vessel operation. Always
use the supplied mounting hardware.
• Leave space around the units to allow
cooling and ensure there are adequate
clearance for cables.
• Ensure the units can be easily removed.
• Vertical (wall) mounting orientation is
required to maintain IP53 rain protection.
equipment to overheat if a wiring fault exists.
• Many parts of a vessel can produce electrical
noise that interferes with the electrical radio
system operation. The ignition system is
the most common source of electrical noise
interference. Before you begin installation,
ensure that the ignition wiring and
connections to the vessel battery are in
good working condition.
• Verify that low resistance connections are
present between the battery negative
terminal, the vessel chassis, and/or the
engine block. All wire connections should
be clean and tight.
WARNING
Do not connect the TR400/OC400 interface
power cable to the unit until the full
installation is completed.
Routing Cables
• Route cables so they are protected from
pinching, sharp edges, and crushing.
• Use grommets wherever a cable must pass
through a hole in a metal panel
• Keep all in-line connectors accessible.
• For an extra clean installation, a hole may
be driven through the surface directly .
Guidelines for Electrical Connections
The system is designed to operate in negative
ground 10 to 32 Volt DC electrical systems only.
If using the DC cable lead:
• The best power connection point for
the positive primary power lead is the
positive terminal of the battery. Often,
direct connection to the battery is
inconvenient, and you may find it easier
to connect the positive leads to the
starter solenoid. Always select a point
as close as possible to the battery.
• Connect the negative primary power leads to
a good ground point on the vessel chassis or
at the battery. If you must attach the negative
primary power lead directly to the negative
pole of the battery, you may optionally insert
a 10-amp fuse (not included) into the ground
(0V) line. Failure to insert a fuse can cause
