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.
