OPERATING IN A SAFE ENVIRONMENT
The PHX20 Wind Turbine has been designed to recognize most unsafe operational situations and to
react safely, but no amount of code can replace the eyes, ears and intelligence of a human. As the
operator/owner of a wind turbine, it is the ultimate responsibility of the local site personnel to
recognize dangerous situations that may occur, and to act accordingly.
THINK SAFETY FIRST!
If it appears that the wind turbine is operating in an unsafe manner it is important to shut down the
system to maintain safety. Some unsafe environments could include the following:
Loud or unexpected noises coming from the wind turbine
Blades spinning at a speed that appear to be out of control
Imbalance of the wind turbine blades (top of tower rocking back and forth)
Ice buildup on the blades
Large storm or other environment changes
In case of dangerous situations with the wind turbine, always decide on personal safety first.
Shutting down the wind turbine should only be accomplished if it is safe to enter the control
room.
In the case of fire or wild electrical connections NEVER approach the wind turbine. In those cases
shutting off power from the property’s main power switch is the safest step. With that in mind, make
note of the location of the property’s main power disconnect switch and be sure that all persons
know how to safely operate (turn off) that switch.
To Stop the wind turbine follow any of these steps.
1. Press the Emergency Stop RED Button on the door of the controller.
2. Press any SHUTDOWN software button on the wind turbine touch screen.
3. Contact QED Technical Support and request a Remote Shutdown (requires an active internet
connection.)

PREVENTIVE MAINTENANCE
In order to maintain the wind turbine system, periodic scheduled system preventive maintenance is
required. All required Inspections should be reported to QED Wind Power for warranty purposes.
Failure to perform required preventive maintenance voids the manufacture’s warranty.
BLADE INSPECTION
1. Clean the blades using a gentle wash solution (such as a car wash solution).
2. Inspect Blades for damage. Report any fissures larger than 1” to QED Wind Power by emailing
a picture and documenting the location.
3. Inspect the leading edge of the blades for paint chipping. Report any findings to QED Wind
Power by emailing a picture and documenting the location.
4. Check torque on the blade plate locking nuts. Torque should be 65ft lbs. Refer to the current
blade installation manual for proper tools. If torque is found to be incorrect, retorque all nuts on
the blade to installation torque specs. This must be reported to QED Wind Power.
5. Inspect blade flange for weld cracks or abnormalities. Report any findings to QED Wind Power
by emailing a picture and documenting the crack’s location.
6. Wax the blades using a high quality car wax (such as Nu-Finish). Waxing significantly extends
the lifetime of blade paint and protective coating.
GREASING: USE ONLY Mobile SCH220 or equivalent grease product.
CHECK THE YAW SYSTEM AND GREASE
1. Pump 5 shots into each of the two yaw system grease zerks.
2. Pump 20 shots into the Tabletop Bearing grease zerk.
3. Inspect the set screw underneath the main pinion gear. Torque should be 15 ft lbs.
4. Apply grease to the circumference of the main tabletop bearing.
5. Check Torque on the main planetary 5/8” retaining bolts. Torque should be 160 ft lbs.
6. Check torque between yaw motor and planetary. Torque should be 35 ft lbs.
7. Confirm Yaw RPM Sensor assembly is not loose. Do not overtighten.
8. Confirm Yaw motor shaft top sensor mount is secure (press fit only)
GREASE THE GENERATOR
1. Pump 10 shots into the front bearing zerk, and 5 shots into the tail bearing zerk.

2. Check that all wires are secure in their terminal blocks. Check for any wire insulation wear.
3. Check that the nacelle junction box is securely fastened to the chassis of the nacelle.
INSPECT THE WIND SENSOR AND LIGHTNING ROD
1. Confirm the security of the wind sensor pole mounting hardware. Make sure all connections are
secure.
2. Confirm the wind sensor is secure in the mount by checking the mounting bolt.
3. Inspect the wind vane and anemometer cups for problems. Never overtighten.
4. Check the security of the wind sensor wire plug.
5. Insert the wind vane’s test set screw to lock the vane in place. View the reported vane “actual”
direction on the HMI.
• Vane position should be 180 (+/- 3degrees.) Report any discrepancies to QED before
raising tower.
• IMPORTANT Remove the vane’s test set screw before raising tower!
6. Confirm the security of the lightning rod.
7. Confirm the security of the lightning conductor wires and their connections.
REMOVE ANY CABLE TWIST FROM TOWER CABLE
1. While tower is lowered, note the condition of the tower cable and record (if there is cable twist)
the direction of the cable twist.
2. Inspect cable for any damage.
3. After tower is raised, unwind any cable twist. Use “CABLE TWIST UNWIND HELP” page for
assistance.
4. Report cable twist to QED once maintenance is complete.
