CE Marking for the EMC Directive 2004/108/EC

EMC
Since this stack controller is only a component part and incomplete in construction it is the responsibility of the
customer to ensure compliance to the relevant international standards.

EMC General Installation Considerations

Earthing Requirements
IMPORTANT
Protective Earth (PE) Connections
NOTE
Local wiring regulations tale precedence and may require the protective earth connection of the motor to be
connected locally, i.e. not as specified in these instructions. This will not cause shielding problems because of
the relatively high RF impedance of the local earth connection.
EMC Earth Connections
For compliance with EMC requirements, we recommend that the "0V/signal ground" be separately earthed.
When a number of units are used in a system, these terminals should be connected together at a single, local
earthing point.
Control and signal cables for the encoder, all analogue inputs, and communications require screening with the
screen connected only at the VSD (Variable Speed Drive) end. However, if high frequency noise is still a
problem, earth the screen at the non-VSD end via a 0.1µF capacitor.
NOTE
Cabling Requirements
Planning Cable Runs
• Keep electrically noisy and sensitive cables apart.
• Keep electrically noisy and sensitive parallel cable runs to a minimum. Separate parallel cable runs by at
least 0.25 metres. For runs longer than 10 metres, separation should be increased proportionally. For
example if the parallel runs were 50m, then the separation would be (50/10) x 0.25m = 1.25m.
• Sensitive cables should cross noisy cables at 90°.
• Ensure EMC filter input and output cables are separately routed and do not couple across the filter.

Protective earthing always takes precedence over EMC screening.
IN ACCORDANCE WITH INSTALLATIONS TO EN60204, ONLY ONE PROTECTIVE
EARTH CONDUCTOR IS PERMITTED AT EACH PROTECTIVE EARTH TERMINAL
CONTACTING POINT.
CONNECT THE SCREEN (AT THE VSD END) TO THE VSD PROTECTIVE EARTH
POINT, AND NOT TO THE CONTROL BOARD TERMINALS.
