Information
Derating
Due to the use of the wall mounting kit SK TIE4-WMK-1-K and SK TIE4-WMK-2-K the frequency inverter no
longer has optimum ventilation. Therefore, especially with 3-phase frequency inverters, the maximum continuous
power output can be considerably lower than is typical for wall mounting. For details, please refer to the technical
data (Section (please see chapter 7.2 "Electrical data" on page 239)).
In size 4 of the SK 2x0E a fan block is integrated as standard, so that no power derating can occur.
