Fuses of the appliance
To protect the appliance or the cable connections to it when an earth leakage fault occurs,
you should install appropriate fuses. Use the fuses listed in

EMC requirements on cable routing (EMC information)
Modern semiconductor technologies are applied in these appliances which minimize the
power loss in the unit by switching more quickly and, with this, to continually reduce the
size of the power section. These semiconductors generate electromagnetic waves due to
the high switching frequency. As a result, when running converters you must meet spe-
cific conditions to avoid electromagnetic influences caused by switching operations.
Disturbances can occur in all sections of the drive system and are caused by:
m
capacitive fault currents caused by high rates of voltage rise when semiconductors
switch.
m
high currents and high rates of current rise in the motor cables. The disturbance energy
bound in magnetic fields reaches frequencies of between a few Hertz and about
30 MHz. Due to the high rates of current rise, additional electromagnetic fields occur
with frequencies of up to approximately 600 MHz.
m
high clock rates and fast logic circuits
(electromagnetic field/16 MHz up to 1 GHz).
m
system perturbation and harmonics. The reason for this are commutation processes
and non-sinusoidal mains network loads especially with network controlled converters
(100 Hz up to 20 kHz).
6.7.1
German EMC law (EMVG)
This appliance complies with § 6 sect. 9 of EMVG dated 18.09.1998:
"Devices, systems and components in the sense of section 3, that are exclusively manu-
factured or stocked as vendor parts or spare parts for further processing by industrial
companies or craftsmen or by other specialists in the field of electromagnetic compatibility
do not need to comply with the protective requirements of § 4 sect. 1 no. 1 to 3 and 5."
EMC largely depends on how the individual components and units are assembled and in-
terconnected within the switching cabinet. The information given on the next pages is in-
tended to enable you to configure your plant according to the newest EMC knowledge.
This way you can keep the respective legal regulations.
6.7.2
Measures to ensure EMC
To ensure EMC you should strictly keep to the following configuring information.
NOTE
In this Manual you find the most important information for an EMC-compatible installation.
Further absolutely notes, which have to be complied with, to mount a CE-confom installation
is to be found in the operation manual „filter for mains applications“.
