About DF5 series frequency
inverters

Intended use
The DF5 series frequency inverters are not domestic appliances.
They are designed only for industrial use as system components.
The DF5 series frequency inverters are electrical apparatus for
controlling variable speed drives with three-phase motors. They
are designed for installation in machines or for use in combination
with other components within a machine or system.
After installation in a machine, the frequency inverters must not be
taken into operation until the associated machine has been
confirmed to comply with the safety requirements of Machinery
Safety Directive (MSD) 89/392/EEC and meets the requirements of
EN 60204. The user of the equipment is responsible for ensuring
that the machine use complies with the relevant EU Directives.
The CE-mark attached to the DF5 series frequency inverters
confirm that, when used in a typical drive configuration, the
apparatus complies with the European Low Voltage Directive
(LVD) and the EMC Directives (Directive 73/23/EEC, as amended
by 93/68/EEC and Directive 89/336/EEC, as amended by 93/68/
EEC).
Frequency inverters of the DF5 series are suitable for use in public
and non-public networks in the described system configuration.
Depending on their location of use, external filtering may be
necessary.
Connection to IT networks (networks without a ground potential
reference point) is not permitted as the devices internal filter capa-
citors connect the network to the ground potential (enclosure). On
earth free networks, this can lead to dangerous situations or
damage to the device (isolation monitoring required).
On the output of the frequency inverter (terminals U, V, W) you
may not:
• connect a voltage or capacitive loads (e.g. phase compensation
capacitor),
• connect multiple frequency inverters in parallel,
• make a direct connection to the input (bypass).
Observe the technical data and terminal requirements. Refer to the
equipment nameplate or label and the documentation for more
details.
Any other usage constitutes improper use.
