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.
