AT THE HUB
Please take care that the color code used at the node is followed exactly when connecting to
the hub. An improperly connected wire may cause the entire system to malfunction or even
damage components.
If the power is connected incorrectly, damage may occur to the connected node. When power
is applied to the hubs, pay special attention to the hub’s LEDs. If the LEDs do not light or are
dim, remove power immediately.
Do NOT apply power to the hubs until the system is ready to test. Power should be applied
one hub at a time while observing the hub’s LEDs. This approach allows problems to be quick-
ly identified and isolated before a large number of nodes are involved.
WARNING! Do not substitute a non-approved power supply.
Verify the following:
• The color code of wires matches the color code used throughout the installation.
• Hub LEDs do not dim or extinguish when power is applied.
• All wires are clearly labeled as to function and location.
• Wires do not have potential short circuit due to exposed copper.
• Network Diagnostic Analyzer shows that the network is OK.
NETWORK CONNECTIONS
Connectors used for connecting wiring between each of the Sonance Navigator Network
devices are high quality spring loaded pressure type connectors. These connectors have been
specifically chosen for their ease of installation and high resistance to failure in adverse condi-
tions. These connectors ensure proper connections between field wiring and network devices.
The two specific types of connectors used are illustrated below along with the recommended
wire stripping measurements. The primary consideration when stripping wires for insertion
into the connectors is that you remove enough of the insulation so the clamping mechanism of
the connector grips the conductor and not the insulation.
The following are examples of connectors used for Sonance Navigator Network connections.
WIRE TYPES
• Solid Core Wires - Special care should be taken not to nick the copper of solid core wires
as the nick will create a weak spot prone to breakage from vibration or flexing of the wires.
• Stranded Wires - Special care should be taken to assure that all the strands are latched into
the connectors. Twist the strands in the natural direction of the cable before inserting them
into the connectors. Loose, shorted strands are a common cause of system malfunction.
• Shielded Wires - Do not use shielded wire with this system.
