2-24
■
Installation of controller
IMPORTANT
In case of installing the RMU, it is recommended to use the EMI shielded cabinet.
Tests under the following standards have been conducted on RMU20 in accordance with the IEC 61326-3-1
standard. For further details, refer to the IEC 61326-3-1 standard.
Description
Immunity to electrostatic discharge
Radiated, radio-frequency, electromagnetic field immunity
Electrical fast transient/burst immunity
Surge Immunity
Immunity to conducted disturbances, induced by radio-frequency fields
Power frequency magnetic field immunity
Voltage dips, short interruptions and voltage variations immunity
2.4.3 Other: processing the cables connected to RMU20
Ensure that a ferrite core with 2 or more turns is installed on the cable to be connected to CNCOM in order to
reduce the noise. Install the ferrite core at a position close to the controller (transmission source). If it is not
positioned correctly, its installation will have minimal effect.
