Grounding
These instructions are intended for all who are responsible for the grounding of the converter.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur, and electromagnetic interference can increase.
• If you are not a qualified electrician, do not do electrical installation or
maintenance work.
• Always ground the converter, the generator and adjoining equipment to ensure
personnel safety in all circumstances, and to reduce electromagnetic emission
and interference.
• Make sure that the conductivity of the grounding conductors is sufficient. See
the converter hardware manual. Obey the local regulations.
• In a multiple-converter installation, connect each converter separately to the
protective earth (PE).
Note:
• You can use power cable shields as grounding conductors only when their
conductivity is sufficient.
• As the normal touch current of the converter is higher than 3.5 mA AC or
10 mA DC, you must use a fixed protective earth connection. See standard
IEC/EN 61800-5-1, 4.3.5.5.2..
