System Wiring
For compliance with the stated EMC radio frequency emission standard the following conditions must be met:
• The specified filter must be used.
• The filter and the drive must be mounted close together on the same metal plate, ensuring direct metallic contact with the plate (the
plate must have a conductive surface, not painted or anodised). The connections between the filter and drive must be as short as
practicable.
•
The screen (shield) of the motor cable must be fixed in direct contact with the same plate. The contact must be by direct contact, no
wire or 〝pigtail〟 is permitted.
• The specified ferrite core must be fitted to the signal cable(s).
•
For compliance with the stated surge immunity standard the specified surge absorber must be fitted as shown in the wiring diagrams
