* Shielded cable length of Frame A should be no longer than 30m and Frame B, C no longer than 50m to prevent
cable length from being too long, which may cause built-in EMC filter malfunction due to overheat resulting from
leakage current and larger wires parasitic capacitance.
EMC Filter Installation
All electrical equipment, including AC motor drives, will generate high frequency/ low frequency noise
and will interfere with peripheral equipment by radiation or conduction when in operation. By using an EMC
filter with correct installation, much interference can be eliminated. It is recommended to use DELTA EMC
filter to have the best interference elimination performance.
We assure that it can comply with following rules when AC motor drive and EMC filter are installed and
wired according to user manual:
1. EN61000-6-4
2. EN61800-3: 1996
3. EN55011 (1991) Class A Group 1
General precaution
To ensure EMC filter can maximize the effect of suppressing the interference of AC motor drive, the
installation and wiring of AC motor drive should follow the user manual. In addition, be sure to observe the
following precautions:
1. EMC filter and AC motor drive should be installed on the same metal plate.
2. Please install AC motor drive on footprint EMC filter or install EMC filter as close as possible to the AC
motor drive.
3. Please wire as short as possible.
4. Metal plate should be grounded.
5. The cover of EMC filter and AC motor drive or grounding should be fixed on the metal plate and the
contact area should be as large as possible.
