Electrical installation
Contents of this chapter
This chapter describes the electrical installation procedure of the wind turbine converter.
WARNING!
Only qualified electricians are allowed to carry out the work described
in this chapter. Read the complete safety instructions of the converter. If you
ignore them, injury or death, or damage to the equipment can occur.
See the circuit diagrams delivered with the converter. The diagrams of this chapter do not
necessarily match the installation-specific circuit diagrams of a tailor-made wind turbine
converter.
Checking the insulation of the assembly
WARNING!
See and obey the safety instructions of the converter. If you ignore
them, injury or death, or damage to the equipment can occur.
Converter
Do not make any voltage tolerance or insulation resistance tests (for example, hi-pot or
megger) on any part of the converter as testing may damage the converter. Every
converter has been tested for insulation between the main circuit and the chassis at the
factory. Also, there are voltage-limiting circuits inside the converter which cut down the
testing voltage automatically.
