13.15 EMC filter class C1/C2
EMC filter according to EN61800-3:2004 class C1 (for
frame size C types) and C2 - 1st environment restricted
distribution.
For sizes B,C, C2, D and D2, the filter is mounted inside
the drive module.
For sizes E and up, external EMC filters are available.
For more information refer to “Technical catalogue for
AC drives”.
Note: EMC filter according to class C3 - 2nd
environment included as standard in all drive units.
13.16 Output chokes
Output chokes, which are supplied separately, are
recommended for lengths of screened motor cable longer
than 100 m. Because of the fast switching of the motor
voltage and the capacitance of the motor cable (both line to
line and line to earth screen), large switching currents can be
generated with long lengths of motor cable. Output chokes
prevent the AC drive from tripping and should be installed
as closely as possible to the AC drive.
See also in “Technical catalogue AC drives” for filter
selection guide.
13.17 Liquid cooling
AC drive modules in frame sizes E - O and F69 - T69 are
available in a liquid cooled version. These units are designed
for connection to a liquid cooling system, normally a heat
exchanger of liquid-liquid or liquid-air type. Heat exchanger
is not part of the liquid cooling option.
Drive units with parallel power modules (frame size
G - T69) are delivered with a dividing unit for connection of
the cooling liquid. The drive units are equipped with rubber
hoses with leak-proof quick couplings.
The Liquid cooling option is described in a separate manual.
13.18 Top cover for IP20/21
version
This Top cover can be mounted on IP20 versions of frame
sizes C2, D2, E2 and F2.
By mounting the top cover, the protection class will change
to IP21 in accordance with EN 60529 standard.
