Installation Diagram of Upper and Down Parts
Caution: When the inverter power is not higher than 22kW, the A size can be
omitted. When the inverter power is higher than 22kW, the A size shall be
higher than 50mm.
Caution: When performing up-down installation of inverter, please install the
thermal insulating guide plate as shown in the diagram.
Table.3-1 Schematic Diagram for Installation of MD280 Inverter
Caution: When the inverter power is no more than 18.5G/22P, dimension A
can be neglected. When the inverter power is higher than 18.5G/22P,
dimension A shall be higher than 50mm.
Caution: When performing up-down installation of inverter, please install the
thermal insulating guide plate as shown in the diagram.
Heat sinking shall be taken into account during the installation. Attention shall
be paid to the following items:
1) Install the inverter vertically so that the heat may be expelled from
the top.However, the equipment cannot be installed upside down. If there
are multiple inverters in the cabinet, parallel installation is better. In the
applications where up-down installation is required, please install the
thermal insulating guide plate referring to the schematic diagrams for
standalone installation and up-down installation.
2) The mounting space shall be as indicated as the above diagrams,
so as to ensure the heat sinking space of the inverter. However, the heat
sinking of other devices in the cabinet shall also be considered.
3) The installation bracket must be made of flame retardant
materials.
4) In the applications where there are metal powders, it is
recommended to install the radiator outside the cabinet. In this case, the
