Chapter 2 Installation
EMI Filter Installation
All electronic equipment (including servo drive) generates high or low frequency noise during
operation and interferes with the peripheral equipment via conduction or radiation. With an EMI
Filter and the correct installation, much interference can be eliminated. It is suggested to use
Delta's EMI Filter to suppress the interference better.
When installing the servo drive and EMI Filter, please follow the instructions of the user manual
and make sure it meets the following specifications:
1. EN61000-6-4 (2001)
2. EN61800-3 (2004) PDS of category C2
3. EN55011+A2 (2007) Class A Group 1
General Precaution
In order to ensure the best performance of EMI Filter, apart from the instructions of servo drive
installation and wiring, please follow the precautions below:
1. The servo drive and EMI Filter should be installed on the same metal plate.
2. When installing the servo drive and EMI Filter, the servo drive should be installed above the
EMI Filter.
3. The wiring should be as short as possible.
4. The metal plate should be well grounded.
5. The metal cover of the servo drive and EMI Filter or grounding should be firmly fixed on the
metal plate. Also, the contact area should be as large as possible.
6. It is suggested to install one servo drive with one EMI filter.
