Safety Instructions

These safety instructions are intended to prevent hazardous situations and /or equipment damage.

These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.”

They are all important notes for safety and must be followed in addition to International Standards (ISO

/IEC), Japan Industrial Standards (JIS)*1) and other safety regulations*2).

*1) ISO 4414: Pneumatic fluid power -- General rules relating to systems

ISO 4413: Hydraulic fluid power -- General rules relating to systems

IEC 60204-1: Safety of machinery -- Electrical equipment of machines (Part 1: General requirements)

ISO 10218-1992: Manipulating industrial robots -- Safety

JIS B 8370: General rules for pneumatic equipment.

JIS B 8361: General rules for hydraulic equipment.

JIS B 9960-1: Safety of machinery – Electrical equipment for machines. (Part 1: General requirements)

JIS B 8433-1993: Manipulating industrial robots - Safety. etc.

*2) Labor Safety and Sanitation Law, etc.

Caution Caution indicates a hazard with a low level of risk which, if not avoided, could result in minor or

moderate injury.

Warning Warning indicates a hazard with a medium level of risk which, if not avoided, could result in

death or serious injury.

Danger Danger indicates a hazard with a high level of risk which, if not avoided, will result in death or

serious injury.

Warning

1. The compatibility of the product is the responsibility of the person who designs the equipment or

decides its specifications.

Since the product specified here is used under various operating conditions, its compatibility with specific

equipment must be decided by the person who designs the equipment or decides its specifications based on

necessary analysis and test results.

The expected performance and safety assurance of the equipment will be the responsibility of the person who

has determined its compatibility with the product.

This person should also continuously review all specifications of the product referring to its latest catalog

information, with a view to giving due consideration to any possibility of equipment failure when configuring the

equipment.

2. Only personnel with appropriate training should operate machinery and equipment.

The product specified here may become unsafe if handled incorrectly.

The assembly, operation and maintenance of machines or equipment including our products must be

performed by an operator who is appropriately trained and experienced.

3. Do not service or attempt to remove product and machinery /equipment until safety is confirmed.

The inspection and maintenance of machinery /equipment should only be performed after measures to

prevent falling or runaway of the driven objects have been confirmed.

When the product is to be removed, confirm that the safety measures as mentioned above are implemented

and the power from any appropriate source is cut, and read and understand the specific product precautions

of all relevant products carefully.

Before machinery /equipment is restarted, take measures to prevent unexpected operation and malfunction.

4. Contact SMC beforehand and take special consideration of safety measures if the product is to

be used in any of the following conditions.

1) Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to

direct sunlight.

2) Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping,

vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and

beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or other

applications unsuitable for the standard specifications described in the product catalog.

3) An application which could have negative effects on people, property, or animals requiring special safety

analysis.

4) Use in an interlock circuit, which requires the provision of double interlock for possible failure by using a

mechanical protective function, and periodical checks to confirm proper operation.

Note 1) The strokes shown in ( ) are produced upon receipt of order.

Note 2) The speed is dependent on the workload. Check the following “Speed-workload graphs” for the selected model.

Note 3) Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and

perpendicular direction to the lead screw. (The test was performed with the actuator in the initial state.)

Vibration resistance: No malfunction occurred in a test ranging between 45 to 2000 Hz, when the actuator was tested in both an axial

direction and a perpendicular direction to the lead screw. (The test was performed with the actuator in the initial state.)

Note 4) The "Power consumption" (including the controller) is for when the actuator is operating.

Note 5) The “Standby power consumption when operating” (including the controller) is for when the actuator is stopped in the set position

during operation.

Note 6) The "Momentary max. power consumption" (including the controller) is for when the actuator is operating.

This value can be used for the selection of the power supply.

Note 7) Only applies to actuators supplied with a lock.

Note 8) For the actuator with lock, please add the power consumption for the lock.
