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.
・ Wiring should be done in a place that is free from dust and water or oil. This
may result in an electric shock, re, or a fault.
・ Do not allow conductive foreign matter, such as screws and metal pieces, or
ammable foreign substances, such as oil, to enter the internals. This may
result in an electric shock, re, or a fault.
・ Be sure to install the unit in such a way that re or personal injury does not
occur during an earthquake.
・ Insulate the power supply terminals connections. Not doing so may result in
an electric shock.
Warning
・ Do not wire or operate with wet hands. It may result in electric shock or
failure.
・ Do not use this product near water, corrosive atmosphere, ammable gas or
harmful gas, or near combustible materials. Not doing so may result in an
electric shock, re, 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, re, or a
fault.
・ Do not use in locations subject to severe vibration or impacts. This may
result in an electric shock, injury, re, or a fault.

1 Cautionary Notes Regarding Safety
Caution
・ Perform wiring correctly and securely. Not doing so may result in an electric
shock, re, or a fault.
・ Install according to the specied mounting method and mounting direction.
Not doing so may result in injury or a fault.
・ Consider each of the specications, 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 re or a fault.
・ Take measures regarding peripheral devices that are a󱐯ected by noise as
noise may be generated by the PWM switching control. Also consider the
installation environment as the unit itself may be a󱐯ected by external noise.
・ Adjust the alignment between the output shaft and the partner device
accurately. Not doing so may result in a fault.
・ When installing the unit vertically, install the unit with the output shaft facing
down, as failing to do so may result in grease owing into the unit. This may
result in a fault.
・ Check and adjust each setting before operation to avoid unexpected
operation. This may result in injury or a fault.
Caution
・ Do not apply any voltage other than the specied 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 re or a fault.
・ Do not use in places where static electricity is generated. This may result in
a re 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 re 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. This 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 o󱐯. Not doing so may
result in an electric shock, injury, re, 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 o󱐯 the power immediately at the power supply and
do not reapply power. This may result in a re or a fault.
・ Do not touch the unit while the power is on or for a while after the power is
turned o󱐯, 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, re, or a fault.
Caution
・ Securely x 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, x the cause and ensure safety before restarting operation.
Not doing so may result in a fault.
・ Turn o󱐯 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, re, 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 o󱐯 excessively frequently. This may result in a
re or a fault.
・ Do not perform continuous operation for extended periods of time. This may
result in a re or a fault.

4 Installation and Connection
■Unit Installation
1. Connect the antenna.
Radio waves are radiated vertically from the antenna axis as
shown below. After connecting the antenna, adjust the angle of
the antenna while considering the directivity of the radio waves.
Wireless communication distance varies depending on the
installation / connection conditions.
The communication distance may be shorter under the following
conditions, and should be considered when determining the
installation location and connection method.
・ There is an obstacle in the transmission path. (Rebar,
reinforced concrete, etc.)
・ There is a height di󱐯erence in the transmission path.
・ The installed position is close to the ground.
・ There is metal around.
・ There is a lot of radio noise in the vicinity.
※ Antenna connection is not necessary for wired
communication.
