1 Cautionary Notes Regarding Safety
1.1 Cautionary Notes Regarding Installation and Wiring
Warning
・ Be sure to perform wiring after installation is complete. Not doing so may
result in an electric shock.
・ Do not allow conductive foreign matter, such as screws and metal pieces, or
flammable foreign substances, such as oil, to enter the internals. This may
result in an electric shock, fire, or a fault.
・ Be sure to install the unit in such a way that fire or personal injury does not
occur during an earthquake.
・ Insulate the cable connections. Not doing so may result in an electric shock.
・ If wiring in a location that is very dusty or may come in contact with water or
oil, process in a manner that will make them resistant to water and dust.
Not doing so may result in an electric shock, fire, or a fault.
Warning
・ Do not perform wiring while hands are wet. It may result in electric shock or failure.
・ Do not use this product underwater, corrosive atmosphere, flammable gas or harmful
gas, or near combustible materials. This may result in an electric shock, fire, or a fault.
・ Do not damage, apply excessive stress, place heavy objects on, pinch, or bend
the cables repeatedly. This may result in an electric shock, fire, or a fault.
・ Do not use in locations subject to severe vibration or impacts. This may result
in an electric shock, injury, fire, or a fault.
Caution
・ Perform wiring correctly and securely. Not doing so may result in an electric shock, fire, or a fault.
・ Install according to the specified mounting method and mounting direction.
Not doing so may result in injury or a fault.
・ Consider each of the specifications, such as the main unit weight and rated
output, when installing and install in an appropriate environment. Not doing
so may result in injury or a fault.
・ Install the unit where the ambient temperature is -5°C to 55°C (non-freezing)
and the ambient humidity is 20%RH to 85%RH (non-condensing). Not doing so
may result in a fire or a fault.
・ Take measures regarding peripheral devices that are affected by noise as
noise may be generated by the PWM switching control. Also consider the
installation environment as the unit itself may be affected by external noise.
・ Adjust the alignment between the output shaft and the partner device
accurately. Not doing so may result in a fault.
・ Check and adjust each setting before operation to avoid unexpected
operation. Not doing so may result in injury or a fault.

1 Cautionary Notes Regarding Safety
Caution
・ Do not apply any voltage other than the specified voltage. This may result in
a fault.
・ Do not stack the units. This may result in a fault.
・ Do not hold the cables or output shaft during transportation. This may result
in a fault.
・ Do not step on the unit or place heavy objects on it. This may result in a
fault.
・ Do not subject the unit to strong impacts such as those caused by dropping
or falling from something. This may result in a fault.
・ Do not use outdoors or under exposure to direct sunlight. This may result in
a fire or a fault.
・ Do not use in places where static electricity is generated. This may result in
a fire or a fault.
・ Do not subject the output shaft to strong impacts. This may result in a fault.
・ Do not subject the output shaft to loads in excess of the allowable load.
This may result in a fault.
・ Do not connect directly to AC power. This may result in a fire or a fault.

1 Cautionary Notes Regarding Safety
1.2 Cautionary Notes Regarding Operation and Maintenance
Warning
・ Wiring, maintenance and inspection should be performed by a specialized
technician. Not doing so may result in an electric shock, injury, or a fault.
・ If an error occurs, stop operation immediately and install an external
emergency stop circuit so that the power can be shut off. Not doing so may
result in an electric shock, injury, fire, or a fault.
Warning
・ Do not move, connect wiring, or inspect while the power is on. It may result
in electric shock or failure.
・ In case of a fault, shut off the power immediately at the power supply and
do not reapply power. Not doing so may result in a fire or a fault.
・ Do not touch the unit while the power is on or for a while after the power is
turned off, as it may be hot. This may result in burns.
・ Never touch the output shaft during operation. This may result in injury.
・ Do not disassemble, repair or modify. This may result in an electric shock,
injury, fire, or a fault.
Caution
・ Securely fix to the device so that it will not come loose during operation. Not
doing so may result in injury or a fault.
・ If a dangerous situation may occur while stopped or if the product fails, install
an external holding brake. Not doing so may result in injury or a fault.
・ If an error occurs, fix the cause and ensure safety before restarting operation.
Not doing so may result in a fault.
・ Turn off the power if not using the product for extended periods of time. Not
doing so may result in a fault.
Caution
・ Do not use a unit while damaged. This may result in injury, fire, or a fault.
・ Do not make extreme adjustments or changes. Such changes may cause
unstable operation.
・ After power is restored in the event of a power outage, do not approach the
equipment because operation may restart all of a sudden. This may result in
injury.
・ Do not turn the power on or off excessively frequently. This may result in a
fire or a fault.
・ Do not perform continuous operation for extended periods of time. This may
result in a fire or a fault.
