4.1. Snapshot of the installation procedure
The installation procedure is described in the follow sections:
Electromagnetic compatibility, EMC
Before fitting
Fitting the motor
Electrical installation
Check that these sections have been read and understood and that, subsequently, the motor has been
installed correctly.
4.2. Electromagnetic compatibility, EMC
DANGER
INTERFERENCE AFFECTING SIGNALS AND EQUIPMENT
Interference with signals can cause equipment to behave
unpredictably
• Wiring should be done in accordance with the EMC
recommendations specific to each device.
• Ensure that these EMC recommendations are followed correctly.
If these precautions are not taken, the result could be death,
serious injury or damage to equipment.
Recommendations with regard to EMC: installing the motor's power supply wiring.
At the wiring planning stage, consider that the motor's power supply wiring must be installed isolated from
network or signal transmission cables.
Take the following measures with regard to EMC.
EMC measures
Effect
Keep cables as short as possible.
Do not install loops of unused cable.
Reduce interference, capacitive and inductive
couplings.
Earth the product.
Reduce emissions; increase immunity to
interference,
Where shielded cables are used, the cable
shielding should be fitted to the widest possible
surface area. Use cable clamps and earth bands.
Reduce emissions.
Position the motor's power supply wires separate
from cables that carry signals or use screening
plates.
Reduce mutual interference
If screened cables are used, fit them without an
isolation point.
1)
Reduce radiating interference.
1) Where the installation requires a cable to be cut, cables must be connected at the isolation point via a shielded cable inside a
metal enclosure.
Equipotential link conductors
Where screened cables are used, differences in voltage can cause currents not permitted in screened
cables. Fit equipotential link conductors to reduce current in screened cables.
