SV600 Series User Manual 4 Electrical wiring and precautions
35
The rated voltage of the electric drive system is less than 1000 V and is suitable for the second
environment and not for the first environment.
C4 level Equipment:
The rated voltage of the electric drive system is equal to or above 1000 V or the rated current is
equal to or above 400A, or use in a complex system of the second environment.
4.3.2 Introduction of EMC standards
EMC Standards
The SV600 series frequency inverter meets the standard EN 61800-3:2004 C2 level
requirements, and applicable to the first class environment and the second class environment.
EMC Requirements of Installation Environment
The manufacturer of the system which installed with the inverter is responsible for the system's
compliance with the requirements of the European EMC Directive. According to the system's
application environment, please ensure that the system meets the requirements of standards
EN61800-3: 2004 Class C2, C3 or C4.
The system (machinery or device) installed with the inverter must also be CE marked. The
responsibility for the final assembly of the system is borne by the customer. Please confirm
whether the system (machinery or device) complies with the European directives and meets the
requirements of standard EN 61800-3: 2004 C2.
Note: In the first class environment, the frequency inverter may cause radio interference. Besides the CE
compliance requirements mentioned in this chapter, users must take measures to prevent interference if
necessary.
4.3.3 Installation of EMC input filter on Power supply input
EMC filter installed between the frequency inverter and the power supply can not only restrict
the interference of electromagnetic noise in the surrounding environment on the inverter, but
also prevents the interference from the inverter on the surrounding equipment.
The SV600 series inverter satisfies the requirements of category C2 only with an EMC filter
installed on the power input side.
The installation precautions are as follows:
When using the filter, please use it strictly according to the rated value. Since the filter is a
Class I electrical appliance, the metal case ground of the filter should have a large area in good
contact with the metal ground of the installation cabinet, and it must have good electrical
continuity, otherwise there will be danger of electric shock and serious affects on the EMC
effect.
The filter ground must be connected to the common ground with the ground of the
frequency inverter PE, otherwise the EMC effect will be seriously affected.
The filter should be installed as close as possible to the power input of the frequency
inverter.
