4. Installation
DANGER
Use explosion-protection type motor in explosive environment. Do not use the standard unit in explosive
environment. Otherwise, it may cause explosion, ignition, electric shock, injury, fire, or damage to the equipment.
Use the sufficient motor for
explosion-protection motor
matching the hazardous location (where explosive gas or
steam exists).
Inverter itself is not explosion-protection type for
flameproof type motor
. Always set the unit where there is no
explosive gas. Otherwise, explosion, ignition, electric shock, injury, fire, or damage of the equipment may occur.
CAUTION
Do not use gearmotor or reducer for specifications other than the one shown on the nameplate or manufacturing
specification document. Otherwise, injury or damage of the equipment may occur.
Do not place any combustible object around the gearmotor. Otherwise, fire may occur.
Do not place any object that may prevent ventilation around the gearmotor or reducer. Otherwise, it may lead to
burn or fire by abnormal temperature caused by the decreased cooling effect.
Do not step on or hang from the gearmotor and reducer. Otherwise, it may cause injury.
Do not touch the shaft end, internal keyway, or edge of motor cooling fin with bare hands. Otherwise, it may
cause injury.
Install and oil pan or other device to prevent damage for extremely oil-sensitive applications, such as food
production machine. Otherwise, it may cause defective products by oil leakage when failure occurs or at the end
of lifetime.
4-1) Place of installation
Ambient temperature: -10~40°C
Ambient humidity: 85% or less
Altitude: 1,000m or lower
Atmosphere: There should be no corrosive or explosive gas or steam.
The location should be free of dust and well-ventilated.
Location: Indoor (location free of dust without water splash)
• Consult us when operating under conditions other than the above. Special specification is necessary.
• Units made according to certain specification, such as for outdoor or for explosion protection, may be used under
specified mounting environment.
• Install the unit in location where various procedures can be carried out easily, such as inspection and maintenance.
• Install the unit to a sufficiently rigid base.
4-2) Angle of installation
Install the unit horizontally. Consult us for sloped installation.
Do not use the unit made for given slope for other slopes.
Standard shaft direction for
outdoor type gearmotor
is horizontal. Consult us for other shaft directions.
• Do not remove the eye-bolt on the motor. When the eye-bolt is removed for any reason, place a bolt in the tapped
hole temporarily. Waterproof treatment is necessary to prevent water entering the motor.
4-3) Under Severe Load Condition
For operation with severe vibration and frequent startup, it is recommended to tighten bolt with at least class 8.8 (by
standard JIS B-1051).
