Specification of enclosed enclosure

For the inverters, the installation of the semiconductor heat sink and brake resistor outside the enclosure allows heat
generated in the enclosure to be greatly reduced to 30% and a compact enclosure to be designed. The following table lists the
heat dissipation area and approximate dimensions of the enclosed dust-proof enclosure with respect to the loss (W).

*3 The values in the above table depend on the operating
conditions and surrounding air temperature. (Heat
generated by other equipment has not been taken into
consideration)
*4 The values in the above table indicate areas effective for
heat dissipation.
*5 When the heat sink is installed outside the enclosure, the
loss indicates the heat generated by the inverter unit in
the enclosure.
