13-11 Output coils
Output coils, 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 coils prevent the VSD from tripping and should be
installed as closely as possible to the VSD.
13-12 Liquid cooling
VSD modules in frame sizes E - K and F69 - K69 are available in a liquid
cooled version. These units are designed for connection to liquid cooling sys-
tem, 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 - K69) 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 on a separate manual.
