1.8 Installation
!
CAUTION
Failure to following recommendation may result in VFD damage, Personal Injury, or Fire.
Be sure to install the unit on flame resistant material such as metal.
Be sure not to place anything flammable such as corrosive gas, explosive gas,
inflammable gas, grinding fluid mist, salt in the vicinity
Do not carry the unit by the top cover, but always by supporting the base of the unit
Be sure not to let foreign matter enter such as cut wire refuse, spatter from welding, iron
refuse, wire, dust, etc.
Be sure to install the VFD in a place which can support the weight according to the
specification in the manual.
Be sure to install the unit on a perpendicular wall which is not subject to vibration.
Be sure not to install and operate a damaged inverter or one with the missed parts
Be sure to install the unit in an area which is not exposed to direct sunlight and well
ventilated. Avoid an environment which tends to be high in temperature, high in humidity
or to have condensation.
1.8.1 Mounting Surface
It is critical to mount the VFD to the proper surface in order to prevent any possible risk of fire. The
temperature of the VFD heatsink can rise very high. The surface must be made of a non-flammable
material (i.e. steel). Attention should also be made to the air gap surrounding the VFD. Especially, when
there is a heat source such as a breaking resistor or reactor.
1.8.2 Mounting Position
Mount the VFD in a vertical position using screws or bolts. The mounting surface should also be free
from vibration and can easily hold the weight of the VFD.
