3.5 Instructions for EMC Requirements
Installation
The regulated standard in accordance with conformity of
electromagnetic is summarized in Regulation CEI EN 61800 (com-
plete).
Microspeed Plus conformity is assured only if it is installed
following the precise assembly criteria expressed below. The
fundamental assembly characteristics are summarized bolow:
--1) Use of appropriate network to filter the line (transformer input),
from disturbances conducted or produced by the drive.
A series of filters released by AXOR are available for this purpose.
--2) Use of shielded cables, both for power connection (to the
transformer and the motor), and for signal connection (also to the
controller).
--3)Using the division of cables technique. Separate power cables
from signal cables.
--4) The correct ground connection of predisposed parts.
Of all of the mentioned system, the use of network filters is without
a doubt fundamental in soppressing disturbances.
Axor, after tests, has recognized some good solutions, about its
products.
Concerning equipment where are mounted other sources, Axor
cant evaluate the global equipment. In the following page, are
reported some foundamental configurations, with the suggested
filters.
We did an agreement with Schaffner and Timonta products. The
market offers other product with the same characteristics, but not
yet checked from Axor.
When other products will be checked and approved, it will be
notified.
Follow reported an example about the noise level with and without
filter as explained in the following pages.
