1.8 Proper use
The DC1 frequency inverters are not domestic appliances. They are designed
only for industrial use as system components.
The DC1 frequency inverters are electrical devices 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
(meets the requirements of EN 60204). The user of the equipment is respon-
sible for ensuring that the machine use complies with the relevant EU Direc-
tives.
The CE markings on the DC1 frequency inverter 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).
In the described system configurations, DC1 frequency inverters are suitable
for use in public and non-public networks.
A connection of a DC1 frequency inverter to IT networks (networks without
reference to earth potential) is permissible only to a limited extent, since the
device’s built-in filter capacitors connect the network with the earth potential
(enclosure).
On earth free networks, this can lead to dangerous situations or damage to
the device (isolation monitoring required).
Observe the technical data and connection requirements.
For additional information, refer to the equipment nameplate or label of the
frequency inverter and the documentation. Any other usage constitutes
improper use.
￫
To the output (terminals U, V, W) of the DC1 frequency inverter
you must not:
• connect a voltage or capacitive loads (e.g. phase compensa-
tion capacitors),
• connect multiple frequency inverters in parallel,
• make a direct connection to the input (bypass).
