1.4.4 Installation
Installation environment
The VF-AS1 Inverter is an electronic control instrument. Take full consideration to installing it in the proper operating
environment.
Warning
Prohibited
• Do not place any inflammable substances near the VF-AS1 Inverter.
If an accident occurs in which flames are emitted, this could lead to fire.
Mandatory
• Operate under the environmental conditions prescribed in the instruction manual.
Operation under any other conditions may result in malfunction.
Caution
Prohibited
• Do not install the VF-AS1 Inverter in any location subject to large amounts of vibration.
This could cause the unit to fall, resulting in bodily injury.
Mandatory
• Check to make sure that the input power supply voltage is +10%, -15% of the rated supply voltage
written on the rating label (±10% when the load is 100% in continuous operation).
If the input power voltage is not +10%, -15% of the rated power voltage (±10% when the load is
100% in continuous operation) this may result in fire.
• Do not install in any location of high temperature, high
humidity, moisture condensation and freezing.
• Avoid locations where there is exposure to water
and/or where there may be large amounts of dust and
metallic fragments.
• Do not install the inverter where there are gases that
corrode metal or solvents that adversely affect plastic.
• Operate in areas where ambient temperature ranges from -10°C to 60°C. When installing the inverter w here the
ambient temperature will rise above 40°C, remove the protective cover from the top cover (depending on the
capacity of the inverter used). When installing the inverter where the ambient temperature will rise above 50°C, it is
necessary to operate in lower current than rated value.

Note: The inverter is a heat-emitting body. Make sure to provide proper space and ventilation when installing in
cabinet. When installing inside a cabinet, we recommend the removal of the protective cover.
