•
Earth-ground system (typically a copper or copper sheathed grounding rod driven
into the ground)
with 16 AWG - 28 AWG copper wire
•
2 spools 16-28 AWG wire (for positive and negative power connections)
• Wire cutters
•
Wire strippers
• Additional tools as required to install the enclosure and mount the antenna
4.3 GENERAL
• The LT1 MUST be mounted in an IP66 weather-proof enclosure that is fitted with a 35mm x
7.5mm DIN rail.
IMPORTANT! The LT1 is designed to operate in a dry, protected environment.
Exposure to rain greater than 1mm per minute, spraying or splashing water may cause
the unit to fail.
• For ease of use, it is recommended to remove the SDI-12 and power terminal blocks from
their ports when making the wire connections.
•
Ensure there is enough slack in all wire connections for the LT1 to be manipulated as
required to mount on the DIN rail without applying strain to any of them.
4.4 POWER REQUIREMENTS
The LT1 requires a 12 volt power source, typically a 12 VDC sealed lead acid battery which may be
used in conjunction with a solar charger.
IMPORTANT! Power connections must be made in the order indicated and in
accordance with manufacturer’s directions for solar panel use to prevent
damage to the station and equipment.
4.4.1 POWER IF USING FT7X2 RS-485 WIND SENSOR HEATER OPTION
The LT1 is designed to work with an FT7 RS-485 wind sensor. If using the heater option on an
attached FT742 RS-485 wind sensor a power source capable of at least 3 A must be attached to both
the PW and HT pins. Details of connecting an FT7X2 RS-485 wind sensor are found in App Note 162
(700-AN-162) and posted to the FTS Support site.
If using a heated sensor, the associated draw on the supplied power must be taken into account to
calculate battery longevity and solar panel requirements.
