3.1.4 Cabinet Mounting
It is possible to mount the inverters: on a surface or a flange. To that end, the following considerations must be
taken into account:
3.1.4.1 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 and the heatsink fan flow at the operation point are
specified in
The position and diameter of the mounting holes, according to
!
WARNING!
UL type 1 inverters support surface mounting only.
3.1.4.2 Flange Mounting
In the flange-mounting type, the back of the inverter (which contains the heatsink and fan) is installed outside the
panel. Therefore, the power module cooling air is kept outside the cabinet.
The mounting brackets must be removed and repositioned as shown in
Dimensions of the opening for mounting the back of the product, position and diameter of the mounting holes,
as shown in
The portion of the inverter that is located outside the cabinet is rated IP55 / UL type 12. To ensure that the cabinet
degree of protection is maintained, adequate sealing must be provided between the panel opening and the drive
flange. Example: silicone gasket.
