1. Upon startup the Running screen displays 'V Detect' and counts down from 45 seconds to zero.
2. The controller records the generator nominal output voltage and compares it to the voltage selector switch set point.
3. If the recorded nominal voltage differs from the selector switch set point by 10% or more, the controller shuts the generator down.
4. Adjust output voltage with the fine voltage adjustment screw (rheostat) below the Control Power switch within the 45 second delay.
5. Check 'L1N' or 'L12' voltage on the Generator screen and turn the screw until it matches the selector switch rating within 10%.

10. Check the frequency is approximately 60 Hz with no loads.
11. Switch the main circuit breaker to ON (I), then add loads by switching the respective circuit breakers to ON (I).

⚠ The unit must be leveled before raising the mast. Failure to level will severely reduce stability and could allow the unit to tip and fall.

⚠ Never raise or lower the mast while the unit is operating. Never remove the safety pin or release the mast lock while the mast is up.

1. Set up and level the unit.
2. Remove the mast cradle locking pin from the mast cradle.
3. Check the mast cables for excessive wear or damage and ensure they are centered in each pulley; check the electrical cord.
4. Make sure the area around the unit is clear before raising the mast to vertical.
5. Remove the safety pin from the mast lock bar and raise the mast until vertical and locked; secure with the safety pin.
6. Use the upper mast winch to telescope the mast to the desired height, keeping the electrical cord extending.
7. Rotate the mast using the mast rotation knob until the lights face the desired direction, then tighten the knob.

⚠ The unit must be leveled before raising the mast.

⚠ Do not start the unit if insulation on the electrical cord is cut or worn through.

1. Set up and level the unit.
2. Remove the mast cradle locking pin from the mast cradle.
3. Check the mast cables for excessive wear or damage and that they are centered in each pulley; check the electrical cord.
4. Make sure the area around the unit is clear before raising the mast to vertical.
5. Press the lower winch control switch upward to raise the mast; hold until the mast lock engages; secure with the safety pin.
6. Press and hold the upper winch control switch upward to telescope the mast to the desired height.
7. Rotate the mast using the mast rotation knob and tighten to secure in position.

1. On units with quick disconnect fittings, disconnect the power cords from the junction box and replace the dust caps.
2. On hard wired units, remove the junction box cover and disconnect ONLY the mast light wires, flipping locking levers down and pulling wires out.
