4.3.3 INSTALLING A DRIVE IN A GROUNDED NETWORK: 525-690 V, ENCLOSURE SIZES
MR10-MR12, AND THE ENCLOSED DRIVES
The 525-690 V drives, enclosure sizes MR10-MR12, and enclosed drives are targeted to
installations in machine rooms or other similar locations. Because the immunity level of
devices that are installed in these locations is higher than usual, the filtering of the drives is
level C3 of the IEC 61800-3 standard.
•
Without actions, the installation complies with the requirements of the special power
distribution and passenger accommodation zones of IEC 60533. However, for the
passenger accommodation zone, we recommend similar compatibility procedures as in
the general power distribution zone.
•
To make a compatible installation in the general power distribution zone, you must make
an EMC plan (refer to IEC 61800-3, Annex E). In the EMC plan, assess the required
amount of high-frequency filtering. See the recommended amount of filtering in Table 4.
You can use this table as a reference when you discuss the correct filtering with your filter or
isolation transformer provider, and with the manufacturers of other devices intended to be
used on the same supply.
