5.1 EMC Information
The frequency inverters are designed according to the requirements and limit values
of product norm EN 61800-3 with an interference immunity factor (EMI) for operation
in industrial applications. Electromagnetic interference is to be avoided by expert
installation and observation of the specific product information.
Measures
•
Install the frequency inverters and commutating chokes on a metal mounting
panel. Ideally, the mounting panel should be galvanized.
•
Provide proper equipotential bonding within the system or the plant. Plant
components such as control cabinets, control panels, machine frames, etc. must
be connected by means of PE cables.
•
Connect the frequency inverter, the commutating choke, external filters and
other components to an earthing point via short cables.
•
Keep the cables as short as possible, make sure that cables are installed properly
using appropriate cable clamps, etc.
•
Contactors, relays and solenoids in the electrical cabinet are to be provided with
suitable interference suppression components.
A
Mains connection
The length of the mains supply cable is not
limited. However, it must be installed separate
from the control, data and motor cables.
B DC link connection
The frequency inverters are to be connected to
the same mains potential or a common direct
voltage source. Cables longer than 300 mm are
to be shielded. The shield must be connected to
the mounting panel on both sides.
C Control Connection
The control and signal cables must be kept physi-
cally separate from the power cables. The shield
of the control cables is to be connected to
ground potential properly, i.e. with good
conductivity, on both sides. Analog signal lines
are to be connected to the shield potential on
one side.
D Motor and brake resistor
A
B
C
D
The shield of the motor cable is to be connected
to ground potential properly on both sides. On
the motor side use a metal compression gland.
On the frequency inverter side an appropriate
shield clamp is to be used. The signal cable used
for monitoring the motor temperature must be
kept separate from the motor cable. Connect the
shield of this line on both sides. If a brake
resistor is used, the connection cable must also
be shielded, and the shield is to be connected to
earth potential on both sides.
Attention! The frequency inverters meet the requirements of the low-voltage direc-
tive 73/23/EEC and the requirements of the EMC directive 89/336/EEC.
The EMC product standard EN 61800-3 relates to the drive system. The
documentation provides information on how the applicable standards
can be complied if the frequency inverter is a component of the drive
system. The declaration of conformity is to be issued by the supplier of
the drive system.
