The part of the inverter that stays outside the cabinet is rated IP20.
The power specified in Table 8.1 on page 8-2 to Table 8.4 on page 8-5 under "Dissipated power in
Watts - flange mounting" will be dissipated inside the cabinet. Use Table 8.1 on page 8-2 and Table 8.3
on page 8-4 for inverters with AC power supply and Table 8.2 on page 8-3 and Table 8.4 on page
8-5 for inverters with DC power supply. The other losses (power modules) will be dissipated at the external
ventilation duct.
The inverter mounting supports and the hoisting eyes must be removed. Refer to the Figure 3.8 on page
3-11, positions I and J.
Dimensions of the flange-mounting opening and the diameters of the securing holes must be according to
