3.5 Mechanical Installation

3.5.1 Installation Environment:

1. Ambient Temperature: The ambient temperature greatly affects the lifespan of the frequency converter. The operating environment temperature of the frequency converter should not exceed the allowable temperature range (-10°C to 50°C).

2. Install the frequency converter on the surface of a flame-retardant object with sufficient space around it for heat dissipation. The frequency converter generates a large amount of heat during operation. Use screws to mount it vertically on the mounting bracket.

3. Install it in a place where vibration is minimal. Vibration should not exceed 0.6G. Pay special attention to staying away from equipment such as punches.

4. Avoid installation in areas exposed to direct sunlight, moisture, or water droplets.

5. Avoid installation in places where there are corrosive, flammable, or explosive gases in the air.

6. Avoid installation in places with oil stains, excessive dust, or metal dust.

Single-unit Installation: When the power of the frequency converter is not greater than 22 kW, consideration of dimension A is optional. When it exceeds 22 kW, A should be greater than 50mm.

Vertical Installation: When installing the frequency converter vertically, please install the depicted heat insulation baffle according to the diagram.

Frequency Converter Power	Installation Dimension A	Installation Dimension B
≤15 kW	Optional	≥100 mm
18.5 kW – 30 kW	≥50 mm	≥200 mm
≥37 kW	≥50 mm	≥300 mm

3.5.2 Mechanical Installation Considerations

Mechanical installation primarily concerns heat dissipation. Therefore, please consider the following points:

1. Please install the frequency converter vertically to facilitate upward heat dissipation. However, do not install it upside down. If there are multiple frequency converters in the cabinet, it is best to install them side by side. In cases where vertical installation is necessary, please refer to the schematic diagram for the installation of the heat insulation baffle.

2. Follow the installation schematic diagram to ensure sufficient space for heat dissipation of the frequency converter. However, when arranging the space, consider the heat dissipation of other components inside the cabinet.

3. The installation bracket must be made of flame-retardant material.

4. For applications with metal dust, it is recommended to install the frequency converter outside the heat sink cabinet. In this case, the fully sealed cabinet space should be as large as possible."
