2.2.3.2 Wall-mounting kit SK TIE4-WMK-1 (up to -3)
The wall-mounting kit SK TIE4-WMK-1 (up to -3) provides a simple method of installing the frequency in-
verter near to the motor. With this kit, the frequency inverter can comply with protection class IP66 (Size
S 4: IP55).
NOTE Derating
With the use of the wall-mounting kit SK TIE4-WMK-1 (or -2) the frequency inverter is no longer
optimally ventilated. 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 8.3).
In size 4 of the SK 2x0E a fan block is integrated as standard, so that no power derating can
occur. However, only a protection class of IP55 can be achieved with size 4.
