3.1.3 Cabinet Mounting
There are two possibilities for mounting the converter: surface 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 Assembly:
Provide adequate exhaustion so that the internal cabinet temperature is kept within the allowable operating
„
range of the converter.
The power dissipated by the converter at its rated condition, as specified in
„
8.4 on page 8-5
"Dissipated power in Watts - Surface mounting".
The cooling air flow requirements, as shown in
„
The position and diameter of the mounting holes, according to
„
page
3-4.
Flange Assembly:
Frame Size E:
The power specified in
Table 8.1 on page 8-2
„
mounting" will be dissipated inside the cabinet. The remaining losses (power module) will be dissipated through
the vents.
The converter securing supports (position H of
„
Figure 2.2 on page
2-5) must be removed and repositioned according to the
Figure 3.6 on page
3-8.
The portion of the converter 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 Sizes F and G:
ATTENTION!
The part of the converter that stays outside the cabinet is rated IP20.
The power specified in
„
- Flange mounting" will be dissipated inside the cabinet. The other losses (power modules) will be dissipated
at the external ventilation duct.
The converter mounting supports and the hoisting eyes must be removed. Refer to the
„
2-6, positions H and I.
Dimensions of the flange-mounting opening and the diameters of the securing holes must be according to
„
the
