Installation location
Install them 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: 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 elds or vacuum
•
Altitude Up to 1000 m (3300 ft.) above sea level
Installing the combination type
Note
•
Do not forcibly assemble the motor and gearhead. Also,
do not let metal objects or other foreign matters enter 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’s pilot
section. If the O-ring is crushed or severed, grease may
leak from the gearhead.

Removing/Installing the gearhead
To replace the gearhead or change the cable outlet direction, remove the
screws assembling the gearhead. The gearhead can be removed and the motor
cable position changed to a desired 90° direction.
1. Remove the hexagonal socket head screws (2 pcs) assembling the motor
and gearhead and detach the motor from the gearhead.
2. Using the pilot sections of the motor and gearhead as guides, install the
gearhead to the motor and tighten the hexagonal socket head screws.
When installing the gearhead, slowly rotate it clockwise/counterclockwise
to prevent the pinion of the motor output shaft from contacting the side
panel or gear of the gearhead.

Combination type • hollow shaft at gearhead
A combination type hollow shaft at gearhead can be installed by using either
its front or rear side as the mounting surface.
Secure the hollow shaft at gearhead using the supplied hexagonal socket
head screws through the four mounting holes you drilled. Tighten the nuts
until no gaps remain between the gearhead and mounting plate.
Attach the supplied safety cover to the hollow output shaft on the end
opposite from the one where the load shaft is installed.
