5. When installing this product in a control panel,
ensure that the ventilation is sufficient to prevent the
ambient temperature of the inverter from exceeding
the specified value. Do not install the product in an
area where there is inadequate ventilation,
6. If two or more inverters must be installed in the
same equipment or control panel, arrange the units
horizontally (side by side) to minimize the effect of
heat. If two or more inverters must be installed
vertically (one on top of the other), place an
insulated plate between the inverters to minimize the
effect of heat.
7. When shipped from the factory, inverters provide
internal cooling inside panel. An inverter of
30HP/CT, 40HP/VT or less can be converted to an
external cooling simply by adding an optional
mounting adapter.
In an external cooling system, the heat sink radiates about 70% of total inverter heat (total
loss) and can be placed outside the control panel (see Fig. 2-2-2). When doing this, ensure
that heat sink surfaces are kept free of foreign matter.
DANGER
･In the case of external cooling system, cover the back of the inverter
in order to prevent the exposure of the power capacitor and braking
resistor as electric shock may result.
･Ensure that the inverter and heat sink surfaces are kept free of
foreign matter such as lint, paper dust, small chips of wood or metal,
and dust, as fire may result.
An inverter of 40HP/CT, 50HP/VT or more can be converted to an external cooling type simply by
moving
upper and lower mounting brackets as shown in Fig. 2-2-3. Remove the M6 bracket screws,
move the brackets, then secure the brackets using the M5 case mounting screws. (The
bracket screws are no longer required after changing the bracket mounting position.)
