5.3 Wiring
5.3.1 Standalone configuration
For standalone configuration the junction box is not necessary; connect
the instrument directly to the power supply.
Note: Turn on the display unit’s terminal resistor. For the procedure, see
page 33 (FI-501/502/505 or page 35 (FI-506)
Using the terminal box
As shown in the figure above, the display unit is connected to the wind
transducer with the cable assy. FI-50-SENSOR-30/50. However, if the
connector of the cable cannot be passed through the mast (because its
diameter is too small), use the Terminal Box to make the connection.
Wire it as shown on the next page. The box is not waterproof; locate it
out of areas subject to rain or water splash. The length of the cable be-
tween the FI-5001 and display units is maximum 50 m.
1. Cut the connector from the FI-50-SENSOR-30/50 cable and pass the
cable thru the mast.
2. Fabricate the above-mentioned cables as shown below.
