Mounting and Connection Considerations
NOTICE
This device should be mounted in a location that is not exposed
to extreme temperatures or conditions. The temperature range
for this device is listed in the product specifications. Extended
exposure to temperatures exceeding the specified temperature
range, in storage or operating conditions, may cause device
failure. Extreme-temperature-induced damage and related
consequences are not covered by the warranty.
The mounting surface must be flat to avoid damaging the device
when it is mounted.
The GRID 20 device requires a power connection and a data
connection, using one of three methods:
• NMEA 2000
®
network for power and data
• Included power cable and an ANT
®
wireless connection
• AA batteries (not included) and an ANT wireless connection
This device can be mounted in a dashboard or other surface
using the included hardware. When selecting a mounting
location, observe these considerations.
• To avoid interference with a magnetic compass, you must not
mount the device closer to a compass than 11.4 cm (4.5 in.).
• You must mount the device in a location that allows room for
the routing and connection of the NMEA 2000 cable, power
cable, or the replacement of the batteries.
• The NMEA 2000 connection method can be used to remove
all risk of issues caused by wireless interference from other
devices and in cases where there are wireless range
concerns. The cables necessary to connect to the NMEA
2000 network are not included.
