2.4.6 Grounding the power generator
These power generators are manufactured in accordance with the standard DIN VDE
0100/Part 551 and DIN VDE 0100/Part 410 with the protective measure of electrical
separation of the IT network, i.e. the neutral point of the generator is not connected to
the generator housing. Grounding by means of the grounding screw (pos. 17-4) on the
power generator and a grounding spike can therefore only be used for dissipation of
static electricity charges.
The equipotential bonding conductor (green/yellow) must however lead to and be con-
nected to all consumers without a break.
However, if the power generator is equipped with a protective circuit fault current pro-
tective circuit (available as an option), the neutral point of the generator must be con-
nected to the power generator unit housing and be connected by means of a grounding
screw and possibly a grounding spike with suitable equipotential bonding. It is important
to ensure that, after grounding and before operating the power generator, the protective
measure is checked by an electrician in accordance with BGV A3 (measurement and test
report) and the
protective measure is tested as functional. Also, here a gap-free connection of all
equipotential bonding conductors and connection of the consumer must be ensured.
Now the power generator is designed as a TN-C-S system.
The electrician is responsible for implementation of protective measures. Any protective
measures should be checked by an electrician for efficiency before commissioning of the
power generator.
