• Type B must be used with three phase drives
If an external EMC filter is used, a delay of at least 50 ms should be incorporated to ensure spurious trips are not seen. The leakage current is likely
to exceed the trip level if all of the phases are not energized simultaneously.
Ground leakage current will increase when operating on a single phase supply, it may be necessary therefore to disconnect the internal EMC filter to
ensure spurious RCD trips are not seen. Instructions for disconnecting the Internal EMC filter are given in section 4.10.3

4.10 EMC (Electromagnetic compatibility)
The requirements for EMC are divided into three levels in the following three sections:
•
Section 4.10.4 General requirements for EMC Ground (earth) connections , this is for all applications, to ensure reliable operation of the drive and
minimise the risk of disturbing nearby equipment. The immunity standards specified in section 4.10 EMC (Electromagnetic compatibility) on
page 61 will be met, but no specific emission standards are applied.
• Section 4.10.6 Compliance with EN 61800-3:2004+A1:2012 (standard for Power Drive Systems) , Requirements for meeting the EMC standard
for power drive systems, IEC 61800-3 (EN 61800-3:2004+A1:2012).
• Section 4.10.7 Compliance with generic emission standards , Requirements for meeting the generic emission standards for the industrial
environment, IEC 61000-6-4, EN 61000-6-4:2007+A1:2011.
The recommendations of section 4.10.4 will usually be sufficient to avoid causing disturbance to adjacent equipment of industrial quality. If particularly
sensitive equipment is to be used nearby, or in a non-industrial environment, then the recommendations of section 4.10.6 or section 4.10.7 should be
followed to give reduced radio-frequency emission.
In order to ensure the installation meets the various emission standards described in:
•
The EMC data sheet available from the supplier of the drive.
• The Declaration of Conformity at the front of this manual.
• Chapter 6 Technical data on page 98.
The correct external EMC filter must be used and all of the guidelines in section 4.10.4 General requirements for EMC Ground (earth) connections on
page 67 and section 4.10.7 Compliance with generic emission standards on page 69 must be followed.
4.10.1 Optional external EMC filters
The external EMC filter details for the Digitax HD M75X drive series are provided in the Table 4-15.

Only type B ELCB / RCD are suitable for use with 3 phase inverter drives.
