A.2.3 Preventing Entry of Foreign Objects
satisfy the regional laws & regulations and related IEC requirements.
A.2.4 Grounding
If using an controller of the 400 V class, tie the neutral point of the controller power
supply to ground.
For the wiring example of controller complying with the Low Voltage Directive, see
Figure 2-39
A.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
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
environment.
1) The controller complies with the EMC directives and standards EN12015:2014 and
EN12016:2013 only when meeting the following requirements:
2)
3) The shielded cable is used as the drive cables between the controller and the
motor. For cable selection and installation, refer to A.4.1 Requirements for
Shielded Cable.
4) The controller and wiring shall be installed by a recommended wiring method.
For details, refer to A.4.2 System Wiring Requirements.
5) 3.2.7 Selection
Guide of Common-Mode Filter.
6) When the controller is installed in the elevator system, the integrator of the
system is responsible for compliance of the system with the European EMC
directive (2014/30/EU) and standards EN12015:2014 and EN12016:2013.
When the system installed with the controller is used for other applications, the inte-
grator of the system is responsible for compliance of the system with the European
EMC directive (2014/30/EU) and standard EN 61800-3: 2004 +A1: 2012 according to the
system application environment.
◆
Besides the CE compliance described in this chapter, take measures to avoid the radio
interference if required.
