4.4 Through-switch cabinet mounting (option)
When mounted by through-switch cabinet mounting,
the heat sink (of enclosure class IP54) of the
VARIPACK frequency inverter is outside the switch
cabinet.
Thus,
• a smaller switch cabinet can be used since a large
portion of the heat generated by the VARIPACK fre-
quency inverter is dissipated outside the switch cab-
inet.
• the ventilation of the switch cabinet can be reduced
to a minimum.
• the VARIPACK frequency inverter can be kept clean
and dry more easily.
