Warning
General
• Provide an emergency-stop device or emergency-stop circuit external to the equipment so that the entire equipment
will operate safely in the event of a system failure or malfunction. Failure to do so may result in injury.
• Immediately when trouble has occurred, stop running and turn off the controller or driver power. Failure to do so
may result in fire, electric shock or injury.
• Be sure to provide a safety cage conforming to EN ISO 13857 to prevent persons from entering the moving range
of the motorized actuator while power is supplied to the motorized actuator. Turn off the main power to the
controller or driver before performing adjustment or inspection in which the motorized actuator is moved manually.
Accidental contact may result in serious injury.
• Never use a motorized actuator in a medical device used in connection with the maintenance or management of
human life or health, or in a transportation system whose purpose is to move or carry people.
• Be sure that personnel with expert knowledge of electrical and mechanical engineering perform the installation,
connection, operation, maintenance and troubleshooting. Failure to do so may result in fire, electric shock or injury.
• Do not transport, install the product, and perform connections or inspections when the power is on. Always turn the
power off before carrying out these operations. Failure to do so may result in electric shock.
• If the protective function of the controller or driver has been actuated, remove the cause and then reconnect the
power source. If the motorized actuator operation is continued without removing the cause, the controller or driver
may malfunction and cause injury or equipment damage.
• Do not disassemble or modify the parts other than those specified in this manual. Doing so may result in electric
shock or injury.

−3−
• When the product is used in a lifting application, choose a motorized actuator equipped with an electromagnetic
brake. Without an electromagnetic brake the motorized actuator will lose its holding brake force when the power is
cut off or upon actuation of the protective function or emergency stop function of the controller or driver. When
this happens, the moving part may drop, causing injury or equipment damage.
• Do not use the electromagnetic brake to decelerate, nor use it as a safety brake. The electromagnetic brake is
designed to hold the motorized actuator position. Doing so may result in injury or equipment damage.
• Be careful not to let the hand get caught in the moving parts of the motorized actuator. Keep your fingers and
objects out of the openings in the motorized actuator. Doing so may result in injury or equipment damage.
• Do not forcibly pull or bend the cable or lift the motorized actuator by holding the cable. Doing so may result in
electric shock or injury.
• Do not touch the controller immediately after the power is cut off, or until the CHARGE LED (lit in red) turns off.
Doing so may result in electric shock due to residual voltage (ESMC-A2,ESMC-C2 only).
• Configure an emergency stop circuit that will cut off the motor’s output power and stop the motorized actuator
upon the detection of an EMG (emergency stop) input.
• Do not use the product in an atmosphere containing explosive, flammable or corrosive gases, in a place exposed to
water, or near flammable objects. Doing so may result in fire, electric shock or injury.
• The terminals on the controller’s front panel marked with symbol indicate the presence of high voltage.
Do not touch the battery while the power is on. Doing so may result in fire or electric shock (ESMC-A2,ESMC-C2
only).
• Handle the air coupler for suction and sensors by following the instructions provided with that product. Failure to
do so may result in injury or equipment damage.
Installing and wiring
• When transporting the motorized actuator, do not hold the motorized actuator by its cables, moving part, air coupler
for suction and air tube for suction. Doing so may result in injury or equipment damage.
• Affix the motorized actuator securely by following the specified installation method. Failure to do so may result in
injury or equipment damage.
• Be sure to install the product in an enclosure to prevent contact with any hands. If the product is likely to come in
contact with any hands, be sure to provide a protective earth. Securely ground the protective earth terminal. Electric
shock may result (only when the motorized actuator is combined with the controller ESMC-A2 or ESMC-C2).
• Do not touch the moving part while the power is supplied. The moving part is cut off from the protective grounding
circuit, so electric shock may result (only when the motorized actuator is combined with the controller ESMC-A2
or ESMC-C2).
• The DC power supply to be connected to the controller or driver should have reinforced insulation on the primary
and secondary sides. Failure to do so may result in electric shock.
• Do not touch the battery while the power is supplied. The battery is connected to the primary circuit, so touching
the battery may result in electric shock (ESMC-A2, ESMC-C2 only).
• When measuring insulation resistance or conducting withstand voltage test, never touch the terminals. Electric
shock may result.
• Keep the input-power voltage of the controller or driver within the specified range to avoid fire and electric shock.
• Connect the product correctly and securely according to the wiring diagram. Failure to do so may result in fire,
electric shock, and equipment damage.
• The motorized actuator to be connected to the controller must always match the motorized actuator model printed
on the controller key name plate (ESMC-K2, ESMC-A2 and ESMC-C2 only).
Operation
• Confirm that all input signals of the controller or driver are set to the OFF state before turning on the power. Also,
confirm the emergency stop method of the machine beforehand and operate the motorized actuator in a condition
where an emergency stop can be executed at any moment if necessary. Doing so may result in injury or equipment
damage.
• Perform return-to-home operation or absolute positioning operation immediately after the power is restored. Failure
to do so may result in injury or equipment damage.
• Turn off the power to the controller or driver in case of a power failure. Failure to do so may result in injury or
equipment damage when the motorized actuator starts suddenly upon power recovery.
• Do not ON the C.OFF input, OF-CRN input and FREE input while the motorized actuator is operating. If the
C.OFF input or OF-CRN input switches to the active state during operation, the motorized actuator will stop and
lose its holding brake force. Doing so may result in injury or equipment damage.

−4−
• Never ON the C.OFF input or OF-CRN input when the motorized actuator is installed vertically, whether the
motorized actuator is operating or stopped. The holding brake force will be lost, and the load may drop. Doing so
may result in injury or equipment damage.
• Do not allow any moving part to collide with the stroke end of the motorized actuator in any operation other than
push-motion return-to-home operation or push-motion operation.
Inspection
• Remove the load from the moving parts before checking the internal parts. Failure to do so may result in injury or
equipment damage.
Caution
General
• Do not use the motorized actuator and controller or driver beyond their specified values. Doing so may result in
injury or equipment damage.
• No one should come close to the motorized actuator beyond the safety distance, except for qualified personnel.
Doing so may result in injury.
• Do not use the sensors supplied with your motorized actuator or the sensor set (accessory) as safety components.
Doing so may result in injury or equipment damage.
• Do not touch the motorized actuator, controller, driver or regenerative unit during operation or immediately after
stopping. The surface is hot and may cause a skin burn(s).
• Measuring insulation resistance or conducting withstand voltage test without shorting all terminals will damage the
controller or driver.
• Conduct the insulation resistance measurement or withstand voltage test separately on the motorized actuator and
the controller or driver. Conducting the insulation resistance measurement or withstand voltage test with the
motorized actuator, controller or driver connected may result in injury or damage to equipment.
• Do not use any battery other than the dedicated battery supplied with the product. Use of any other battery may
result in injury or damage to the equipment, controller, driver or battery.
• Do not perform direct teaching unless the motorized actuator is installed in the horizontal direction. When
performing direct teaching, the motor will lose its holding brake force and the load may drop. The motor’s output
current will be cut off, and the electromagnetic brake will be released as well. Doing so may result in injury or
equipment damage.
• If the emergency stop button on the teaching pendant is pressed or any of the protective functions of the controller
or driver is actuated, the controller or driver will cut off the motor output current and stop the motor. If the
motorized actuator is equipped with an electromagnetic brake, the brake is actuated and the position is held.
However, if there is no electromagnetic brake, the holding brake force is lost and it may take longer to stop. If the
load installed on the moving parts is likely to contact other equipment during this period, provide a safety
mechanism on the machine side. Doing so may result in injury or equipment damage.
• Static electricity may cause the controller, driver or controller key to malfunction or sustain damage. Do not touch
the controller or driver while the power is being supplied. When adjusting the DIP switches or the function select
switches while the power supply is active, always use an insulated screwdriver.
Installing
• The motorized actuator is very heavy. When transporting or installing the motorized actuator, make sure two
persons work together to carry out the necessary tasks. Failure to do so may result in injury.
• Wear a helmet, safety shoes, gloves or other protective gear when transporting or installing the motorized actuator.
Failure to do so may result in injury.
• Be sure to install the supplied cover before operating the motorized actuator. Failure to do so may result in injury.
• Lay the suction tubes specified for the EZSⅡSeries (clean room specification) and EZ-Drive equipped EZS Series
(clean room specification) by preventing sharp bends. In addition, keep the tube length to a minimum, since a
longer tube will make it difficult to obtain the specified flow rate.
• To ensure the specified cleanliness of the EZSⅡSeries (clean room specification) and EZ-Drive equipped EZS
Series (clean room specification), suction air from the slide at the specified flow rate. Dust may enter due to a
residual pressure if the suction vacuum pump or blower stops. Provide the necessary devices to prevent this
problem. Failure to do so may generate dust.
