3.1. Overview of the Installation Procedure
The installation procedure is described in the following sections:
Electromagnetic Compatibility (EMC)
Prior to Mounting
Mounting the Motor
Electrical Installation
Connecting the holding brake (optional)
Check that these sections have been read and understood, and that installation has subsequently been
executed correctly.
3.2. Electromagnetic Compatibility (EMC)
DANGER
INTERFERENCE AFFECTING SIGNALS AND EQUIPMENT
Disturbed signals can cause equipment to behave unpredictably.
• Wire up products in compliance with the specific EMC
recommendations for each device.
• Make sure that these EMC recommendations are executed correctly.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
Recommendations in terms of EMC: Installing the motor power supply leads
When planning the wiring, take account of the fact that the motor power supply leads must be kept separate
from line supplies or cables carrying signals.
Comply with the following measures as concerns EMC.
Measures relating to EMC
Effect
Keep the cables as short as possible.
Do not install unnecessary cable loops.
Reduces stray couplings, both capacitive and
inductive.
Ground the product.
Reduces emissions, improves immunity to
interference.
If using shielded cables, install the cable
shielding so that it is in contact with the widest
possible surface area, use cable grips and
ground strips.
Reduces emissions.
Keep the motor power supply leads separate
from cables carrying signals or use shielding
plates.
Reduces stray cross-couplings.
If using shielded cables, install the cables without
any disconnection points.
1)
Reduces stray radiation.
1) When a cable is disconnected for installation, the cables must be connected at the disconnection point via a shelding
connection and a metal box.
Equipotential bonding conductors
If using shielded cables, differences in potential can generate unauthorized currents on the cable shielding.
Use equipotential bonding conductors to minimize currents on the cable shielding.
