Cabinet Mounting - WEG CFW-11 Series User Manual

3.1.3 Cabinet Mounting

There are two possibilities for mounting the inverter: through the wall mounting or flange mounting (the heatsink
is mounted outside the cabinet and the cooling air of the power module is kept outside the enclosure). The
following information shall be considered in these cases:
Surface Mounting:
Provide adequate exhaustion so that the internal cabinet temperature is kept within the allowable operating
range of the inverter.
The power dissipated by the inverter at its rated condition, as specified in
8.4 on page 8-5
The cooling air flow requirements, as shown in
The position and diameter of the mounting holes, according to
page 3-4 and Figure 3.2 on page
Flange Mounting:
Frame Sizes B, C and D:
The losses specified in
flange mounting" will be dissipated inside the cabinet. The remaining losses (power module) will be dissipated
through the vents.
The mounting supports shall be removed and repositioned as illustrated in
The portion of the inverter that is located outside the cabinet is rated IP54. Provide an adequate gasket for
the cabinet opening to ensure that the enclosure rating is maintained. Example: silicone gasket.
Mounting surface opening dimensions and position/diameter of the mounting holes, as shown in
on page 3-3.
Frame Size E:
The losses specified in
flange mounting" will be dissipated inside the cabinet. The remaining losses (power module) will be dissipated
through the vents.
The inverter securing supports (position I of

For models 53 A, 63 A, 80 A and 107 A, the portion of the inverter that is located outside the cabinet
is rated IP54. Provide an adequate gasket for the cabinet opening to ensure that the enclosure rating is
maintained. Example: silicone gasket.
