Installation
All electrical equipment, including AC servo drives, will generate high-frequency/low-
frequency noise and will interfere with peripheral equipment by radiation or conduction when
in operation. By using an EMI filter with correct installation, much of the interference can be
eliminated. It is recommended to use Delta's EMI filter to have the best interference
elimination performance.
We assure that it can comply with following rules when AC servo drive and EMI filter are
installed and wired according to user manual:
EN61000-6-4 (2001)
EN61800-3 (2004) PDS of category C2
EN55011+A2 (2007) Class A Group 1

General Precaution

To ensure the best interference elimination performance when using Delta's EMI filter, please
follow the guidelines in this user manual to perform wiring and/or installation. In addition,
please also observe the following precautions:
EMI filter and AC servo drive should be installed on the same metal plate.
Please install AC servo drive on same footprint with EMI filter or install EMI filter as close
as possible to the AC servo drive.
All wiring should be as short as possible.
Metal plate should be grounded.
The cover of EMI filter and AC servo drive or grounding should be fixed on the metal plate
and the contact area should be as large as possible.
