General Product Philosophy
Compumotor products that were not designed originally for EMC compliance, such as the
APEX615n, will require specific measures to be taken during installation. These measures
vary according to the type of product. The ultimate responsibility for ensuring that the EMC
requirements are met rests with the systems builder.
It is important to remember that for specific installations, the full protection requirements of
the EMC Directive 89/336/EEC need to be met before the system is put into service. This
must be verified either by inspection or by testing. The following EMC installation
instructions are intended to assist in ensuring that the requirements of the EMC directive are
met. It may be necessary to take additional measures in certain circumstances and at specific
locations.
It should be stressed that although these recommendations are based on expertise acquired
during tests carried out on each of the product types, it is impossible for Compumotor to
guarantee the compliance of any particular installation. This will be strongly influenced by
the physical and electrical details of the installation and the performance of other system
components. Nevertheless it is important to follow all the installation instructions if an
adequate level of compliance is to be achieved.
Safety Considerations
These products are intended for installation according to the appropriate safety procedures
including those laid down by the local supply authority regulations. The recommendations
provided are based on the requirements of the Low Voltage Directive and specifically on
EN60204. It should be remembered that safety must never be compromised for the purpose of
achieving EMC compliance. Therefore in the event of a conflict occurring between the safety
regulations and the following recommendations, the safety regulations always take
precedence.
