COMPATIBILITY (EMC) Filters:
All modern PWM variable speed drives use fast switching power devices to achieve high efficiency
and to reduce motor noise. This results in electromagnetic interference (EMI) and radio frequency
interference (RFI). For operational reasons the interference may need to be suppressed.
EMC DIRECTIVES
This Inverter is able to comply with the EMC Directives 89/336/EEC on limits to EMI and RFI with
the use of an optional filter. Independent testing has demonstrated compliance to the following
standards when the optional filters are used.
