5.1 Trip
F60
Trip F60 is situated on the nacelle controller (pos. 4). Trip F60 disconnects the high voltage supply for
the turbine. When disconnected, only the control system in the turbine is supplied from the UPS for
approx. 6 hours. Usually, the local power station must take part when the turbine is connected to the
grid.
5.2 Lift
(Optional)
If a lift is installed, it has several emergency stop buttons.
Note: These buttons only stop the lift; emergency stop buttons for turbine do not apply to the lift.
5.3 Internal
Crane
The crane is equipped with an emergency stop button. This only applies to the crane and otherwise
the emergency stop buttons in the turbine do not apply to the crane.
6.
Practical Advice at Inspection
When inspecting the machinery, always look very closely for oil spills and loose bolts. Dirt must be
wiped off, otherwise it can be difficult to determine whether there is a significant leak.
Loose bolts in the structure mean danger. They must be tightened immediately. If it is a matter of
several bolts or repetitions, please contact Vestas Wind Systems A/S service department.
7.
Influence by Lubricants
The lubricants used in the turbine can be aggressive. Lubricants must not
get in contact with skin or clothes.
At inspection of a gearbox if removing a cap while the oil is still hot, be
careful not to breathe in the hot oil vapours.
8. High
Voltage
Installations
As a basic rule it is not allowed to dismount cover or open locked doors to the high voltage
installations.
An operator/service technician is only allowed to move around behind the covering when the high
voltage is disconnected, locked and visibly earthed. The work must be carried out and approved by
authorised personnel only (power station or selected coupling leader). One of these persons must
give permission to access the HV installation.
Work done on high voltage installations must be carried out in accordance with national regulations
and related Vestas Wind Systems A/S manuals.
