Preventing Entry of Foreign Objects
The drive units must be installed in a reproof cabinet with doors that provide effective
electrical and mechanical protection. The installation must conform to local and regional
laws and regulations, and to relevant IEC requirements.
■
Grounding
If using an AC drive of the 400 V class, tie the neutral point of the drive power supply to
ground.
9.1.3 EMC Guidelines Compliance
Electromagnetic compatibility (EMC) describes the ability of electronic and electrical devices
or systems to work properly in the electromagnetic environment and not to generate
electromagnetic interference that inuences other local devices or systems.
In other words, EMC includes two aspects: The electromagnetic interference generated by
a device or system must be restricted within a certain limit; the device or system must have
sufcient immunity to the electromagnetic interference in the environment.
The drive satisfies the European EMC directive 2004/108/EC and the standard EN 61800-3:
2004 +A1: 2012 Category C2. The AC drives are applied to both the rst environment and the
second environment.
CAUTION
When applied in the rst environment, the AC drive may generate radio
interference. Besides the CE compliance described in this chapter, take
measures to avoid the radio interference if required.
The integrator of the system installed with the AC drive is responsible for compliance of the
system with the European EMC directive and standard EN 61800-3: 2004 +A1: 2012 Category
C2, C3 or C4 according to the system application environment.
