Preparation of mounting holes
● Prepare mounting holes at the same time with backplate processing. For
dimensions of the mounting holes, see "Overall Dimensions".
● To avoid damage to the AC drive during transportation, in addition to fixing
screws, use self‑clinching nuts or independent nuts on the back of the backplate
to enhance screw‑thread fitting and fastening effect.
4.2.4 Cabinet Heat Dissipation Design
Heat dissipation design for the cabinet door
Forced‑air cooling is implemented using the built‑in fan for the AC drive. Provide an
air inlet with an appropriate size on the cabinet door to ensure enough cooling air
entering the cabinet.
The air flows upward due to thermal expansion. Therefore, ensure that the cabinet air
inlet is at least 50 mm lower than the air inlet of the AC drive, as shown in the
following figure.
