5.2.1 Supply forms / electrical supply conditions
Observe the restrictions for the different supply forms!
Supply system Operation of controller Notes
Supply system: TT,
TN
(with earthed
neutral) Permitted without restrictions. l Observe the rated data of the
controller
l RMS mains current: see chapter
"Technical data".
Supply system: IT
(with isolated
neutral) Possible if the controller is
protected in the event of an earth
fault in the supply system
l by means of suitable devices
which detect the earth fault and
l immediately separate the
controller from the supply
system.
l Safe operation in the event of an
earth fault at the inverter output
cannot be guaranteed.
l The variants V024 / V104 and
V100 enable operation of the
controller on IT systems.
DC supply via

/−U
G
Permitted if the DC voltage is
symmetrical to PE. Earthing of the +U

or −U

conductor will destroy the
controller.
5.2.2 Operation on public supply systems (compliance with EN 61000−3−2)
European standard EN 61000−3−2 defines limit values for the limitation of
harmonic currents in the supply system. Non−linear consumers (e.g.
frequency inverters) generate harmonic currents which "pollute" the
supplying mains and may therefore interfere with other consumers. The
standard aims at assuring the quality of public supply systems and reducing
the mains load.
)
Note!
The standard only applies to public systems. Mains which are
provided with a transformer substation of their own as in
industrial plants are not public and not included in the
application range of the standard.
If a device or machine consists of several components, the limit
values of the standard apply to the entire unit.
With the measures described, the controllers comply with the limit values
according to EN 61000−3−2.

Compliance with the requirements 1)
< 1 kW With mains choke
> 1 kW No measures required
1) The additional measures mentioned have the effect that solely the controllers meet the
requirements of EN 61000−3−2. The machine/system manufacturer is responsible for the
compliance with the requirements for the machine/system!
