Figure 9-15Additional EMC measures
The converters are designed for use on industrial supply networks according to
VDE 0160. A ratio of PN/PA of 1/100 is assumed. Under this condition, the se-
ries reactor limits the line supply dips, caused by the general converter opera-
ting principle, to permissible values, which allows other loads, which are suitable
for industrial applications, to be used on the same line supply network.
If there are unfavorable line supplies and/or grounding conditions at the installa-
tion site where the equipment is mounted, then in exceptional cases, cable–
borne disturbances can occur. These are as a result of excessive line reac-
tance. In cases such as these, filter modules or line filters should be used. (can
be used with line supply voltages up to 415V).
Note
We recommend that the pre–assembled cables are used, as perfect screening
is required for an optimum EMC connection.
Further, for optimum signal transfer appropriate cable parameters are required.
A guarantee for the correction functioning is only given when the original manu-
facturers cables are used.
Also refer to the ”EMC Guidelines for SINUMERIK/SIMODRIVE and SIROTEC
controls”.
