DANGER
- Do not use the unit in an explosive atmosphere. Use an explosion proof motor in that case; Otherwise, explosion, ignition, an
electric shock, injury, a fire, or damage to the equipment may occur.
- Use an appropriate explosion proof type motor in a danger zone (which is likely to be filled with explosive gas or steam);
Otherwise, explosion, ignition, an electric shock, injury, a fire, or damage to the equipment may occur.
- For inverter driven flame proof motor ,the inverter unit is not explosion proof construction. So be sure to place it in a location
where there is no explosive gas. Otherwise, explosion, ignition, an electric shock, injury, a fire, or damage to the equipment
may occur.
CAUTION
- Do not use the products for purposes other than those shown on the nameplate or in the manufacturing specifications; oth-
erwise, electric shock, personal injury, or damage to the equipment may result.
- Do not place inflammables around the gearmotor; otherwise, a fire may occur.
- Do not place any objects that hinder ventilation around the gearmotor or speed reducer; otherwise, cooling effects may be
reduced, leading to a fire hazard due to excessive heating.
- Do not step on or hang from the gearmotor or speed reducer; otherwise, injury or damage to the equipment may result.
- Do not touch the shaft end of the products, inside keyways, or the edge of the cooling fan with bare hands; otherwise, injury
may result.
- When the unit used in food processing applications which is vulnerable to oil contamination, install an oil pan or other such
device to cope with oil leakage due to failure or limited service life; otherwise, oil leakage may damage products.
- Before installing, moving or transporting the equipment, be sure to drain off the lubricating oil. If you move the equipment
when it contains lubricating oil, the lubricating oil may flow out from the air bleed plug.
4-1 Location of Installation
Ambient temperature:
−10 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 and free from dust.
Location of installation: Indoor type:
Indoor (free from dust or water splash)
Outdoor type: Indoor or outdoor (area with little contact with rain water)
Vibration:
1G max.
- Mounting In conditions other than the above requires adherence to optional specifications. Please consult with us.
- Drives built according to special specifications, such as explosion proof, can be used In the specified Mounting environments. How-
ever, concerning the connector to the machine used, implement measures based on the Mounting environment.
- Mount In a location that enables easy operation, such as inspection and maintenance.
- Mount on a sufficiently rigid base.
4-2 Mounting Angle
Install the gearmotor or speed reducer so that the output shaft and the motor shaft are horizontal or vertical.
(The mounting direction will depend upon the model, so refer to P4. Also, when you wish to install it obliquely, please contact us.)
Note, however, that if the product is manufactured according to your designated mounting angle, do not use it at any other mount-
ing angle.
Do not remove the eyebolt from the motor. If it is removed for some reason, insert a bolt, etc., into the threaded hole to prevent
water from entering the motor.
4-3 Severe Load Conditions
We recommend using mounting bolts of strength at least class 8.8 (as indicated in JISB-1051), for conditions with strong vibrations or
frequent start-stop.
