1.4.4 Installation■Installation environment
The VF-nC1 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-nC1 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-nC1 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.
Prohibited
•Avoid operation in any location where there is direct spraying of the following
solvents or other chemicals. The plastic parts may be damaged t o a certain degree
depending on their shape, and there is a possibility of the plastic cover s 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.
(Table 1) Examples of applicable chemicals and solvents
(Table 2) Examples of unapplicable chemicals and solvents
Note:The plastic cover has resistance to deformation by the above applicable
solvents. They are not examples for resistance to fire or explosion.
•Do not install in any location of high
temperature, high humidity, moisture
condensation and freezing and avoid
locations where there is exposure to water
and/or where there may be large amounts
of dust, metallic fragments and oilmist.
•Do not install in any location where
corrosive gases or grinding fluids are
present.
