Installation
This section explains the installation method of a load in addition to the installation
location and installation method of the product.
Installation location
Install the product in a well-ventilated location that provides easy access for inspection.
The location must also satisfy the following conditions:
Install it onto an appropriate flat plate having excellent vibration resistance and heat
conductivity.
•
Inside an enclosure installed indoors (provide a ventilation hole)
•
Operating ambient temperature 0 to +50 °C [+32 to 122 °F] (non-freezing)
•
Operating ambient humidity 85% or less (non-condensing)
•
Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid
•
Area not exposed to direct sun
•
Area free of excessive amount of dust, iron particles or the like
•
Area not subject to splashing water (rain, 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
•
Altitude Up to 1000 m (3300 ft.) above sea level
Installation method
Note
Do not install the motor to the mounting hole diagonally or assemble the
motor forcibly. Doing so may cause damage to the flange pilot section,
thereby resulting in damage to the motor.
z
Combination type-parallel shaft gearhead
Secure the motor and gearhead through four mounting holes using the included
mounting screw set. Do not leave a gap between the product and mounting plate.

Removing/Installing the gearhead
See the following steps to replace the gearhead or to change the cable outlet position.
Removing the gearhead from the motor
Remove the hexagonal socket head screws (2 places)
assembling the motor and gearhead, and detach the
gearhead from the motor.

Assembling the gearhead to the motor
1.
Keep the pilot sections of the motor and
gearhead in parallel, and assemble the
gearhead with the motor while slowly
rotating it clockwise/counterclockwise.
At this time, note so that the pinion of the
motor output shaft does not hit the side
panel or gears of the gearhead strongly.
Change the cable
position to a desired
90° direction.
Pilot section
2.
Check no gaps remain between the motor and gearhead, and tighten them with
hexagonal socket head screws (2 places).

Note
•
Do not forcibly assemble the motor and gearhead. Also, prevent metal
objects or foreign substances from entering in the gearhead. The pinion
of the motor output shaft or gear may be damaged, resulting in noise or
shorter service life.
•
Do not allow dust to attach to the pilot sections of the motor and
gearhead. Also, assemble the motor and gearhead carefully by not
pinching the O-ring at the motor pilot section. If the O-ring is crushed or
severed, grease may leak from the gearhead.
z
Combination type-hollow shaft flat gearhead
A combination type-hollow shaft flat gearhead can be installed by using either its front or
rear side as the mounting surface.
Secure the motor and gearhead through four mounting holes using the included
mounting screw set. Do not leave a gap between the product and mounting plate.
Nuts are not included with the 200 W and 400 W types. Provide nuts separately or drill
tapped holes in the mounting plate.
Attach the included safety cover to the hollow output shaft on the end opposite from the
one where the load shaft is installed.
