Radiated & Conducted Emissions: Compliance Overview
In a domestic environment, this product may cause radio interference, in
which case supplementary mitigation measures may be required.

Conducted emission solutions true for default switching frequency of inverter. Operation at higher switching frequencies will
require extra filtering.
The drive is suitable for use on TN supplies when fitted with the internal
filter. When used on an IT supply, all Y-cap connections to earth need to
be removed, hence the filter effectiveness is reduced.
Refer to ‘Chapter 6: Installation’ for details on how to remove the Y-cap
and VDR disconnects when installing the product on an IT supply.
Conducted Emissions Plots
Where a solution is required that is not met by the AC15 product range offering, filtered emissions plots
have been provided to allow specialist EMC filter design companies to tailor a design to meet the
customer’s needs.
Notes on Conducted Emissions Plots:
- Plot is of ‘worst’ line phase of largest power rating, of a given frame size.
- All tests carried out with an unloaded motor.
- Shielded motor cable, 25m in length was used.
- All filter capacitors were connected in circuit (i.e., Y-Caps) for each test.
