To comply with the regulation levels determined by the Japan
Electrical Manufacturers' Association in accordance with the
"harmonic suppression guideline for household appliances and

CAUTION
Install the equipment on a non-flammable material. Not doing so can
cause a fire.
Do not place flammable materials near the equipment. Doing so can
cause a fire.
Install the unit in a load-bearing place. Not doing so can cause an
accident.
Noise environment
Since drive is an electronic piece of equipment, the drive unit may malfunction if
there are machines which generate large noises (e.g. welder, power equipment)
in the periphery. Fit surge suppressors, noise filters and/or like to the noise
sources, install the drive unit as far away as possible from noise sources, or
place shielding plates and the like to fully suppress noises.
CAUTION
The drive unit itself can be the source of noises. Take noise
suppression measures to prevent peripheral equipment from
malfunctioning due to noises.
