Electromagnetic Compatibility, EMC
This product meets the EMC requirements in accordance with the standard IEC 61800-3,
provided that the EMC measures described in this manual are complied with during installation.
If not, signal interference can cause unexpected responses of device.
WARNING
SIGNAL AND DEVICE INTERFERENCE
• Install the wiring in accordance with the EMC requirements.
• Verify compliance with the EMC requirements.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
These devices are not intended to be used on a low-voltage public network which supplies
power to domestic premises. Radio frequency interference is expected if used in such a
network. If used in a residential or domestic premise, additional shielding and filters may be
required, as determined by the systems integrator.
WARNING
HIGH-FREQUENCY INTERFERENCE
Do not use these products in domestic electrical networks.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
EMC measures
Effect
Keep cables as short as possible. Do not install unnecessary cable loops,
use short cables from the star point in the control cabinet to the external
ground connection.
Reduces capacitive and
inductive interference.
Ground the product via the motor flange or with a ground strap to the
ground connection at the cover of the connector housing.
Reduces emissions, increases
immunity.
Ground shields of digital signal wires at both ends by connecting them to
a large surface or via conductive connector housings.
Reduces interference
affecting the signal wires,
reduces emissions
Connect large surface areas of cable shields, use cable clamps and
ground straps
Reduces emissions.
The following cables must be shielded:
• Supply voltage
VDC
• Multifunction interface
• Service interface
