3.9 Installation of high IP insert for size 5
The standard drive is rated to IP20 pollution degree 2 (dry, non-conductive contamination only)
(NEMA 1). However, it is possible to configure the drive to achieve IP65 rating (NEMA 12) at the rear
of the heatsink for through-panel mounting (some current derating is required).
On drive size 5, in order to achieve the high IP rating at the rear of the heatsink it is necessary to seal
a heatsink vent by installing the high IP insert as shown in Figure 3-16.
