CHAPTER-13: CE MARKING
The
Axpert-Eazy Series AC Drive complies with the EMC Directives and Low Voltage Directives.
Observe the following matters when using the inverter as an EMC Directive compliant product.
This Instruction details how to meet the EMC directives (89/336/EEC) with
Axpert-Eazy . It is important
to understand before installation and operation of drive. The Axpert-Eazy is designed to meet the
EMC directives and are suitable for use in the Industrial Environments. These drives have been tested
with the power cables and control leads connected as shown in Fig. 13-1. If these drives are
connected with fewer control leads than these examples, it may be possible to reduce installation
costs by using ordinary cables rather than screened cables which are recommend in this manual. It is
strongly advised however that a compliance test should be performed under the actual operating
conditions to certify that the system complies with the relevant EMC requirements. If the drives are
used with any of the optional cards, you must provide suitable extra measures and must certify
through a test that the product, system or installation complies with the relevant EMC requirements.
This instruction also details how to use filters for the installation where the drives are installed as
stand-alone equipment without being fitted into any enclosure, and the installation where the drives
are installed inside a metal enclosure.
WARNING
This manual represents Amtech's recommendations based on its understanding of the EMC
regulations only and Amtech cannot accept responsibility for any legal problems arising from or in
connection with the use of its products.
Amtech have made every effort to ensure that their products comply with the directives laid out in
the certificate of conformity, which is supplied with each drive. In the case of EMC, the testing has
been carried out using the filters, which are recommended for each product.
The EMC directives set out immunity requirements for the electrical drive (ability to work properly
without being affected by external electromagnetic disturbance), in addition to the previously enforced
emission requirements (electromagnetic disturbance generated by the electrical drive).
In addition to the radiated noise directly generated from the drive and its connected cables, the
emission requirement includes the conducted noise, which is conducted outside the drive through the
input cables.
Immunity is the ability of a drive to operate properly without being affected by an external disturbance.
The EMC compliance is only achieved when the drive's immunity level exceeds its emission level
under its operating environment.
In addition to the immunity against a radiated and conducted disturbance, the EMC directive also
requires of the drive the immunity against static electricity discharges and fast transients.
A human body can easily be charged with static electricity by merely walking on carpet and with a
mere touch on the drive, this static electricity will be discharged through it. A discharging spark can be
at such a magnitude that it can damage the drive.
A drive which is installed near cables connected to a switching inductive load can often operate
incorrectly due to a fast transient induced on its control leads at a switching of the inductive load.
These are just a few examples of disturbance to which the drive is exposed, and the drive is now
required to operate correctly without being affected by such disturbance.
