3. Cable and wire connections -- between the sensor and the indicator
1) Use 5-core shielded cable with 0.5 mm
2
or better
2) Usable cable diameter: 8.6 to 10.5 mm
3) Should be far away from high-tension or large-current circuits.
4) A portable lightning arrester is included in the product. If your region is prone to
lightning or if a long cable is used, either add a lightning arrester near to the
generator or use an underground cable.
There is a portable lightning arrester in the generator. Due to limited space, a
large-capacity lightning arrester cannot be supplied. If your region is prone to
lightning, it is recommended to install an external lightning arrester of a larger
capacity.
4. Wire connections to the sensor
1) Connect the wires by referring to the wiring diagram.
2) To prevent rain water from entering the waterproof connector, make sure that
the rubber packing is properly fixed and the connection to the sensor is firmly
secured.
3) The grounding terminal is located outside the generator. Be sure to connect a
heavy cable for grounding (E3).
“Do not forget to ground the circuit to prevent electric shock or to ensure stable
operation of instrument.”

. Maintenance
This instrument can be used without adding oil for a long period. An inspection should
be performed at least once a year as follows.
1) Check that the propeller and tail fin are smoothly turning when the wind speed
is low (around 2 m/s). Or, check if they can smoothly turn and stop when
manually moved. If the movement is not smooth, add oil or contact us for
replacement of the ball bearing.
2) To maintain the accuracy, the instrument should be tested once every four or
five years, or should be overhauled.
