To ensure good heat dissipation of the inverter unit, design the air inlet and outlet as follows:
Air inlet area formula: S

Violation of the requirements in 3.3.5.1 Installation space and heat dissipation will
shorten the inverter unit life and may result in inverter unit failure or malfunction.

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.
