4. Installation
DANGER
Do not use a standard unit in an explosive atmosphere (which is likely to be filled with explosive gas or steam).
Under such conditions, an explosion-proof motor should be used; otherwise, electric shock, personal injury,
explosion fire, or damage to the equipment may result.
Since the inverter itself is not explosion-proof, install an inverter-driven, explosion-proof type motor in a place
free from explosive gas; otherwise, electric shock, personal injury, explosion fire, or damage to the equipment may
result.
CAUTION
Do not use the Beier variator for purposes other than those shown on the rating plate or in the manu-facturing
specifications; otherwise, electric shock, personal injury, or damage to the equipment may result.
Do not place flammable objects around the Beier variator; otherwise, fire may result.
Do not place any object around the Beier variator that will hinder ventilation. Insufficient ventilation can cause
excessive heat build-up that may result in burns or fire.
Do not step on or hang from the Beier variator; otherwise injury may result.
Do not touch the shaft end of the Beier variator, inside keyways, or the edge of the motor cooling fan with bare
hands; otherwise, injury may result.
When the unit is used in food processing applications vulnerable to oil contamination, install an oil pan or other
such device to cope with oil leakage due to breakdown or faillure; otherwise, oil leakage may damage products.

4-1) Installation Location
Ambient temperature : -10°C to +40°C
Ambient humidity : 85% max.
Altitude : 1000m max.
Ambient atmosphere : There should be no corrosive gas, explosive gas, or steam.
The location should be well ventilated without dust.
Installation location : Indoors, with minimum dust and no water splashing.
• Units made to special specifications are necessary for installation under conditions other than the above.
• Units made according to the outdoor, explosion-proof or other specifications can be used under the specified conditions
without any problem.
• Install units where inspection, maintenance, and other such operations can be easily carried out.
• Install units on a sufficiently rigid base.
4-2) Installation Angle
Grease lubricated model Free
Oil lubricated model Low speed shaft Horizontal or Vertical (Refer to page 5. Contact us inclined installation.)
Table 2 Installation Angle
When the unit is made according to your specification for inclined installation, do not install it at any angle other than the
specified angle. (The shaft orientation of the standard outdoor variator is horizontal. Contact us for other shaft
orientations.)
• Do not remove the eyebolt on the motor. Should the eyebolt be removed, put a bolt into the threaded hole or take other
water-proofing measures to prevent water from entering the motor through the threaded hole.
