C.1.6 EMC installation suggestions
To ensure electromagnetic compatibility (EMC), the following installation points should be
considered to help reduce interference:
H
Earthing/grounding of all system elements to a central earth/ground point (star point)
H
Shielding of all cables and signal wires
H
Filtering of power lines.
A proper enclosure should have the following characteristics:
H
All metal conducting parts of the enclosure must be electrically connected to the back
plane. These connections should be made with an earthing/grounding strap from each
element to a central earthing/grounding point (star point).
*
H
Keep the power wiring (motor and power cable) and control wiring separated. If these
wires must cross, be sure they cross at 90 degrees to minimize noise due to induction.
H
The shield connections of the signal and power cables should be connected to the shield
rails or clamps. The shield rails or clamps should be conductive clamps fastened to the
cabinet.
**
H
The cable to the regeneration resistor must be shielded. The shield must be connected to
earth/ground at both ends.
H
The location of the AC filter has to be situated close to the drive so the AC power wires
are as short as possible.
H
Wires inside the enclosure should be placed as close as possible to conducting metal,
cabinet walls and plates. It is advised to terminate unused wires to chassis ground.
*
H
To reduce earth/ground current, use the largest suitable wire available for earth/ground
connections.
*
Earthing/grounding in general describes all metal parts which can be connected to a
protective conductor, e.g. housing of cabinet, motor housing, etc. to a central earth/ground
point (star point). This central earth/ground point (star point) is then connected to the main
plant (or building) earth/ground.
**
Or run as twisted pair at minimum.
