The EMC filters for 620 Vector drive modules may be flash tested in circuit up to DC 2850 V for 1 min Ensure all
other equipment that may be damaged by such flash testing has been suitably isolated/removed/short circuited as
applicable. Due to the internal capacitors between phase and earth, the DC voltage should be wound up slowly, to
prevent excessive earth current. For similar reasons AC flash testing cannot be performed due to the excessive earth
leakage current. Repeated flash testing is not recommended as it may degrade the insulation.

For end users of 620 Vector drive modules, a correctly installed power drive system (PDS) created from the supplied
620 Vector drive will be compliant with the generic emission standards EN50081-1(1992) and EN50081-2(1994)
and for immunity EN50082-1(1992) and prEN50082-2(1992) as previously indicated.
Manufacturers/suppliers/installers of relevant apparatus may use this compliance as a basis for their own justification
of overall compliance with the EMC Directive.
If it is the responsibility of the manufacturer/supplier/installer to establish EMC conformity and to 'CE' mark. There
are three methods of demonstrating conformity:
1)
Self certification to a relevant standard
2)
Third party testing to a relevant standard
3)
Writing a technical construction file stating the technical rationale as to why the relevant apparatus is
compliant. An EMC "competent body" must then assess this and issue a technical report or certificate to
demonstrate compliance.
Upon demonstrating EMC compliance an EC-Declaration of Conformity for the apparatus or machine may be issued
and a 'CE' mark applied.
Professional end users with EMC expertise who are using drive modules and cubicle systems defined as
components who supply, place on the market or install the relevant apparatus must take responsibility for
demonstrating EMC conformance and applying the 'CE' mark and issuing an EC Declaration of Conformity.
