4.3.6 EMC Issues
The IMC15 has been designed to fulfill the low voltage direc-
tive as well as the EMC directives provided the installation has
been carried out correctly. EMC- certification has been obtai-
ned in an accredited laboratory. The results may not be uncon-
ditionally applied to any type of installation containing an
IMC15.
In order to fulfill the EMC-directives attention has to be paid to
the following points:
1 Ensure good electrical connection between mounting base
and device (use tooth locked washers)
2 Ground the shielding of the motor cable onto the mount-
ing plate as close as possible to the device
3 Use shielded motor cable
4 Ensure good grounding of load
5 Use line filter (mfr Schaffner EMC, Type FN3258-30-33 or
FN3258-30-47, or mfr. FUSS, type 3F460-030.270)
6 Be sure to have good connections to the central grounding
point of the plant
7 Use shielded cable for the control lines, be sure to ground
the shielding properly
8 Use mounting rail as shielding point for AMB cables
Hint: Be sure to connect mounting base well to the central
grounding point of the plant.
