Danfoss VLT AutomationDrive FC 360 Design Guide

RFI filters
The goal is to obtain systems that operate stably without radio frequency interference between components. To achieve a high level of
immunity, use drives with high-quality RFI filters.
 NOTICE
RADIO INTERFERENCE
In a residential environment, this product can cause radio interference, in which case supplementary mitigation measures may be
required.
PELV and galvanic isolation compliance
All drives control and relay terminals comply with PELV (excluding grounded Delta leg above 400 V).
Galvanic (ensured) isolation is obtained by fulfilling requirements for higher isolation and by providing the relevant creepage/clearance
distances. These requirements are described in the EN 61800–5–1 standard.
Electrical isolation is provided as shown (see the following illustration). The components described comply with both PELV and the
galvanic isolation requirements.
