The kits in the following table use the thermal protection of a GV2 manual starter and have a Type 1
rating per UL 50. The insulation system is suitable for use in a Pollution Degree 3 environment (refer to
NEMA ICS-1 Annex A). The package is UL/CSA marked.
ADDITIONAL EMC INPUT FILTERS
Function
The ATV31 drive has built-in radio frequency interference (RFI) input filters to meet EMC “product”
standards for adjustable speed drives, IEC/EN 61800-3, and to comply with the European EMC
(electromagnetic compatibility) directive.
The additional filters enable the drives to meet more stringent requirements: they are designed to
reduce conducted emissions on the line supply below the limits of standards EN 55011 class A (1) or
EN 55022 class B. These filters mount beneath ATV31H drives via tapped holes, acting as supports for
the drives.
Considerations for isolated or impedance grounded neutral systems
The standard IEC 61800-3, annex D2.1, indicates that on isolated or impedance grounded neutral
systems, the filters can affect the operation of insulation monitors.
The efficiency of additional filters on this type of system also depends on the nature of the impedance
between neutral and earth and is therefore unpredictable.
If installing a machine on an isolated or impedance grounded neutral system, one solution is to insert an
isolation transformer and connect locally to the machine on a neutral connection or neutral-to-earth system.
