1. Introduction
Thank you for choosing the EOS-500 Marine Anemometer from EOS Weather Instruments.
EOS has designed and built the EOS-500 to the highest standards for years of reliable, dependable, and
accurate service. The EOS-500 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless installed
and maintained in the correct manner. Please read carefully and follow these instructions for
installation and usage of the EOS-500 in order to ensure optimal performance.
The signal from the EOS-500 is a standard NMEA 0183 signal and can directly be transmitted to any
device accepting the NMEA 0183 protocol. The EOS-500 only provides relative wind speed and direction.
2. Installation
The EOS-500 is a high accurate Anemometer and includes various sensitive parts. Great care must be
taken when handling and installing this high precision equipment. Installation is easy, however
following safety advice should be adhered to:
-Do NOT install your system near any power- or any other utility lines.
-Do NOT install the Anemometer before taking all necessary safety pre-cautions.
-Ensure a free flow of wind around the sensor
After unpacking the system from its packaging carefully observe that no damages are visible. If any
damaged equipment is observed, immediately contact us.
After unpacking your shipment, ensure the following parts are inside the packaging:
oMain unit incl. 60’ (18m) cable
oWind vane
oAnemometer cups
-IR 761 Display unit incl. mounting hardware
-Power cable

2.1 Required Tools
For ease of installation, the EOS-500 is partially pre-assembled. Some minor assembly is required. The
included mounting hardware makes the installation easy and quick. The tools required for the
installation:
-Regular (-) screw driver
-Wrench (12mm or 1/2”)
2.2. Pre-assembly of the Wind vane.
For the ease of shipping of your station, the Wind vane and the Anemometer cups have been removed.
-Line up the arrow on the top shaft with the “N” on the housing.
-Gently push the wind vane onto the shaft with the point aligned to the “N”
-Ensure that the vane is properly seated on the shaft.
-Secure the vane by tightening the point of the wind vane.

2.3. Pre-assembly of the Anemometer.
-Insert the cup assembly onto the shaft and secure the screw.
-Ensure that the cup assembly is properly seated on the shaft.
oDON’T OVERTIGHTEN THE SCREW !
2.4. Installing the EOS-500.
The pole for the Wind vane / anemometer should be about 2” (5 cm) in diameter. Ensure that the pole
you select for the unit is strong enough to withstand high winds and will not cause any bending or
vibration.
-Use a wrench to secure the ¼” U-bolts.
-Ensure that the “N” on the housing will point towards North or the Bow of the vessel.
