• Do not touch the connection terminal of the capacitor immediately after
the power is turned off (for a period of 30 seconds). The residual voltage
may cause electric shock.
• Do not disassemble or modify the motor. This may cause electric shock or
injury.
Caution
• Do not use the motor beyond its specifications, or electric shock, injury or
damage to equipment may result.
• Do not touch the motor during operation or immediately after stopping.
The surface is hot and may cause a burn.
• Do not hold the motor output shaft. This may cause injury.
• Keep the area around the motor free of combustible materials in order to
prevent fire or a burn.
• To prevent the risk of damage to equipment, leave nothing around the
motor that would obstruct ventilation.
• To prevent bodily injury, do not touch the rotating parts (output shaft) of
the motor during operation.
• When an abnormality is noted, turn off the power immediately, or fire,
electric shock or injury may occur.
• The motor’s surface temperature may exceed 70 °C, even
under normal operating conditions. If a motor is accessible
during operation, post the warning label shown in the figure
in a conspicuous position to prevent the risk of burns. Warning
label
• To dispose of the motor, disassemble it into parts and components as much
as possible and dispose of individual parts/components as industrial waste.

Installation
Location for installation
Install it in a well-ventilated location that provides easy access for inspection.
The location must also satisfy the following conditions:
• Inside an enclosure that is installed indoors (provide vent holes)
• Operating ambient temperature
−10 to +40 °C (+14 to +104 °F) (non-freezing)
−10 to +50 °C (+14 to +122 °F) for 100 V/200 V
• Operating ambient humidity 85% or less (non-condensing)
• Area that is free from an explosive atmosphere or toxic gas (such as
sulfuric gas) or liquid
• Area not exposed to direct sun
• Area free of excessive amount dust, iron particles or the like
• Area not subject to splashing water (storms, water droplets), oil (oil
droplets) or other liquids
• Area free of excessive salt
• Area not subject to continuous vibration or excessive shocks
• Area free of excessive electromagnetic noise (from welders, power
machinery, etc.)
• Area free of radioactive materials, magnetic fields or vacuum
• 1000 m or less above sea level
Note On rare occasions, a small amount of grease may ooze out
from the gearhead. If there is concern over possible
environmental damage resulting from the leakage of
grease, check for grease stains during regular inspections.
Alternatively, install an oil pan or other device to prevent
leakage from causing further damage. Oil leakage may
lead to problems in the customer’s equipment or products.
