Grounding
If using an controller of the 400 V class, tie the neutral point of the controller power supply to
ground.

Wiring Example
For the wiring example of controller complying with the Low Voltage Directive, see Figure 3-11 in Chapter

12.3 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 controller satises the European EMC directive 2004/108/EC and the standard EN 61800-3: 2004
+A1: 2012 Category C2. The controllers are applied to both the rst environment and the second
environment.
WARNING
When applied in the rst environment, the controller may generate radio interference. Besides the CE compliance
described in this chapter, take measures to avoid the radio interference if required.
To enable the controller to meet the EMC standard, users need to install the EMC lter on the input side of
the controller, use the shielded cable as the output cables, and ensure that the lter is grounded reliably
and that the shield of the output cables is 360° grounded.
The integrator of the system installed with the controller 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.
