Electrical safety devices, safety measures and earthing
7.3.1
Electrical protection and earth / potential equalization
Generators without the “insulation monitor with disconnection” option meet
the protective measure “electrical separation with potential equalization
connector” according to VDE 0100, Part 728.
Generators with the “insulation monitor with disconnection” option meet
the higher-level protective measure “electrical separation with insulation
monitor” according to VDE 0100, Part 728.
There is no need to earth the generator in order for the electrical safety
measures mentioned above to work properly (e.g. through an earthing rod).
However, if this is still required or if it should become required in special
cases, a pre-defined earthing of the generator housing must be done, or
the generator housing must be added to a potential equalization with other
units.
Only use the earthing points exclusively provided for this purpose and
marked with the earth symbol
.
Danger
Danger to life through electric shock
y
A grounding of the neutral conductor of the generator
(N, neutral conductor) invalidates the “electrical separation”
protective measure.
►
Never ground the neutral conductor of the generator.
►
If the neutral conductor N still needs to be earthed, this
work may only be carried out by a qualified electrician.
A fault current (FI) protective switch must be downstream of
the generator output. Carry out suitable measurements to
verify the effectiveness of the electrical safety measures.
