emi filTer insTallaTion
Electrical equipment like the GS4 drive, will generate electrical noise when in operation and
may interfere with the normal operation of peripheral equipment. The use of an EMI filter will
mitigate this type of power supply interference. Other measures may be required for reduction
or mitigation of radiated emissions. Roxburgh EMI filters have been tested with the GS4 family
of drives and are recommended for the mitigation of interference and the highest performance
(Please refer to the "Input Side of AC Drive" section of the "Line Reactor Applications and Wiring
Connections" chapter in this appendix.
When the GS4 drive and Roxburgh EMI filter are installed and wired according to the user manual,
the installation will conform to the following rules:
•
EN61000-6-4
•
EN61800-3: 1996
•
EN55011 (1991) Class A Group 1 (1st Environment, restricted distribution)
general PreCaUtiOn
1)
Install the EMI filter and GS4 drive on the same subpanel or metal plate�
2)
Install the EMI filter as close as possible to the GS4 drive�
3)
Keep wiring between the EMI filter and GS4 drive as short as possible�
4)
The subpanel or metal plate used to support the EMI filter and GS4 drive should be well
grounded (minimal resistance to ground is typically less then 1Ω).
5)
To insure that the EMI filter and GS4 drive are adequately grounded, insure that both are
securely attached to the subpanel or plate�
ChOOse sUitable MOtOr Cable anD PreCaUtiOns
Proper installation and the the choice of good motor cable will positively affect the performance
of the filter. When selecting motor cable, please observe the following precautions.
1)
Cable shielding (double shielding is best)�
2)
Ground the shield on both ends of the motor cable� Maintain minimum length and employ
strong mechanical connection to ground�
3)
Remove paint on the metal saddle, subpanel or plate to insure good contact to ground�
