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, not painted.
Provide proper equipotential bonding within the system or the plant. Plant com-
•
ponents such as control cabinets, control panels, machine frames, etc. must be
connected by means of PE cables.
The shield of the control cables is to be connected to ground potential properly,
•
i.e. with good conductivity, on both sides (shield clamp). Mount shield clamps for
cable shields close to the unit.
• Connect the frequency inverter, the commutating choke, external filters and oth-
er 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.
