ACD320user manual
Installation and wiring
The user shall focus on the heat dissipation issues when installing the inverter, and pay attention
to the following points:
1) Install the inverter vertically so that the heatmay be expelled from the top, but do not install
the inverter upside down.When twoVariable SpeedDrives are mounted up and dow n, an air flow
diverting plate should be fixed in between as shown in Fig. 3-1.
2) Installation space is shown in Fig.3-1 so as to ensure the heat dissipation space, but consider
the heat dissipation of other components when placing the inverter.
3) The installation bracket must be flame retardant.
4) Install the heat sink outside of the cabinet if the inverter is installed in the area with metal
powder. And in this case, the space inside the sealing cabinet shall be big enough.
