Rating

VLD (Very Light Duty)
*1. The operation of 1,400V-class inverter is only allowed at input voltage below 500 VAC. In case the voltage
exceeds 500 VAC by power supply fluctuation, operate the inverter below 40°C in ambient temperature.
Installation Conditions
Inverters might be heated up to 150°C and might cause fire accident. Install the inverter on the
non-flammable vertical wall (made of metals and others).
Keep the inverter clear of heating elements such as a braking resistor or reactor so that the heat emit-
ted does not influence the operation.
If the inverter is installed in a control panel, take into consideration dimensions and ventilation to keep
the ambient temperature within the range of the specifications.
To allow heat radiation from inside the inverter, provide the clearance specified in the figure below. Do
not install more than one inverter side by side without clearance.
