Sealing sponge
To ensure good heat dissipation of the inverter unit, design the air inlet and outlet as follows:
Air inlet area formula: S
S: System ventilation area
S : Each module ventilation area (cm
module
Air outlet area formula: S
For details about the air volume required by the units, see Table 3-1.

3.3.5.2 Cabinet requirements
It is recommended that the cabinet adopts the nine-fold profile cabinet (PS cabinet). Before installing the
inverter unit, install two bottom support crossbeams, an installation bracket, and an installation rail in the
cabinet, and design the installation crossbeam for inverter unit fixing, and reserve fixing holes on the
installation crossbeam (see Appendix B for the specific location and size).
Fix the bottom support crossbeams and installation bracket. See Figure 3-11.
