Cooling circuit
See chapter The internal cooling circuit.
If the converter has been stored over one year: The electrolytic DC capacitors in the DC link of the
converter have been reformed. See the reforming instructions (available from your local ABB
representative).
There is an adequately sized protective ground conductor between the generator and the converter.
The grid voltage matches the nominal input voltage of the converter.
The grid cables have been connected to appropriate terminals (incoming cubicle terminals L1, L2
and L3), the phase order is correct, and the terminals have been tightened (pull conductors to
check).
The rotor-side cables have been connected to appropriate terminals (inverter cubicle terminals U2,
V2 and W2), the phase order is correct, and the terminals have been tightened (pull conductors to
check).
The DC resistors (D150+D151) have been connected to appropriate terminals (R+ and R),
and the terminals have been tightened (pull conductors to check).
The rotor cable is routed away from other cables.
The generator cable (and DC resistor cable, if present) has been routed away from other cables.
No power factor compensation capacitors are connected to the rotor terminals.
The external control cables have been connected to appropriate plug-in terminals on the connection
board on the right-hand side of the converter.
There are no tools, foreign objects or dust from drilling inside the converter.
Shrouds are fastened and doors are closed.
The input voltage can not be connected to the U2, V2 and W2 terminals of the converter.
Ensure that the lead-throughs fulfil the requirements of degree of protection IP54 or higher.
The generator and the wind turbine are ready for start.
The cooling circuit joints are tight (modules, liquid-cooling unit etc.).
Bleed valves in all cubicles are closed (converter, liquid-cooling unit).
The external control cabling (if any) has been connected to appropriate LCU terminals.
