3.3 EMC Precautions
To achieve interference-free operation of the DeviceNet:
•
Maintain high distance (min. 200 mm [8"])
between the DeviceNet communication cable and
the motor and brake resistor cables to avoid
coupling of high frequency noise from one cable
to the other.
•
When crossing is unavoidable, ensure that the
DeviceNet cable crosses motor and brake resistor
cables at an angle of 90
°
.
NOTICE
Observe relevant national and local regulations, for
example regarding protective earth connection.
