78 Installation checklist
Checklist
Make sure that …
The ambient operating conditions meet the specifications given in chapter
The converter has been fixed properly on an even, horizontal and non-flammable floor and if
necessary due to vibration etc, also from top to the wall or roof.
The cooling circuit joints are tight.
All bleed and drain valves have been closed.
The internal cooling circuit has been filled with coolant that meets the specification. See section
on page
.
The internal cooling circuit has been bleeded. See section
Filling up and bleeding the internal cooling
on page
.
There is an adequately sized protective earth (ground) conductor between the converter and the main
grounding busbar of the wind turbine.
The generator is properly grounded.
All protective earth (ground) conductors have been connected to the appropriate terminals and the
terminals have been tightened (pull the conductors to check).
The voltage of the grid transformer matches the nominal voltage of the grid-side converter. Check the
type designation label.
The grid cable or grid busbars have been connected to the appropriate terminals, the phase order is
right, and the terminals have been tightened. (Pull the conductors to check.) For tightening torques,
see section
on page
The generator cable has been connected to the appropriate terminals, the phase order is right, and
the terminals have been tightened. (Pull the conductors to check.) For tightening torques, see section
on page
The generator cable (and DC resistor cable, if present) has been routed away from other cables.
Converters which have a DC chopper (D150) with a customer-acquired and installed DC
resistor: The DC resistor has been installed, connected to the appropriate terminals, and the
terminals have been tightened. (Pull the conductors to check.)
Test the DC resistor installation by measuring. Measure the resistance of each DC resistor from the
cabinet DC resistor connectors. Ensure that the resistance value is within the allowed minimum and
maximum values defined for the chopper circuit.
The control cables have been connected to the appropriate terminals, and the connections are tight.
(Pull the conductors to check.)
The capacitor unit of the LCL filter has been connected to the appropriate terminals, and the terminals
have been tightened. (Pull the conductors to check.) For tightening torques, see section
on page
.
Test the LCL filter installation by measuring. Measure the LCL filter capacitance symmetrically in each
phase in the grid-side converter cubicle.
There are no tools, foreign objects or dust from drilling inside the converter.
All shrouds and cover of the generator connection box are in place. Cabinet doors have been closed.
The converter is ready for start-up.
