1.4.4 Installation
■ Installation environment
The VF-S9 Inverter is an electronic control instrument. Take full consideration to installing it in the proper
operating environment.
Danger
Prohibited
• Do not place any inflammable substances near the VF-S9 Inverter. If an accident occurs in which flame
is emitted, this could lead to fire.
Mandatory
• Operate under the environmental conditions prescribed in the instruction manual.
Operations under any other conditions may result in malfunction.
Warning
Prohibited
• Do not install the VF-S9 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 voltage is +10%, -15% of the rated power 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.
Warning
Prohibited
• Avoid operation in any location where there is direct spraying of the following solvents or other chemi-
cals. The plastic parts may be damaged to a certain degree depending on their shape, and there is a
possibility of the plastic covers coming off and the plastic units being dropped.
If the chemical or solvent is anything other than those shown below, please contact us in advance.
Note: The plastic cover has resistance to deformation by the above applicable solvents. They are
not examples for resistance to fire or explosion.
