4 NOTES FOR SAFE OPERATION
Read this manual thoroughly before usage, storage, transportation, installation, wiring, opera-
tion, and maintenance and inspection.
„ USAGE
• Any person having electronic medical devices such as a pacemaker must not approach the magnet track of
the linear servomotor.
Failure to observe this warning may result in malfunction of the electronic medical device.
• Be sure to use nonmagnetic tools when installing or working close to the linear servomotor.
(Example: a beryllium-copper alloy hexagonal wrench set, made by NGK Insulators, Ltd.)
• If starting an operation with the linear servomotor in a machine, set the linear servomotor to always allow
emergency stops.
Failure to observe this warning may result in injury.
• Perform wiring after installing the linear servomotor.
Failure to observe this warning may result in electric shock.
• While wiring, be certain to wire the linear servomotor main circuit cables correctly.
Failure to observe this warning may result in malfunction or product failure.
• Ground the grounding terminals of the linear sevomotor according to local electrical codes.
Incorrect grounding may result in electric shock.
• Use ground wires of the sizes specified for internal wiring.
• Keep the wiring distance as short as possible and wire high-voltage lines separately from low-voltage lines.
If noise enters signal lines, oscillation or faulty operation may result.
• Always turn off the power supply and wait at least five minutes before performing wiring or inspection work.
Failure to observe this warning may result in electric shock.
• Do not damage, press, exert excessive force or place heavy objects on the cables.
Failure to observe this warning may result in electric shock, stopping operation of the product, or burning.
• Do not remove the cables, connectors, or optional items while the power is ON.
Failure to observe this warning may result in electric shock.
• Never touch the moving coil of the linear servomotor during operation and never approach the moving range
during operation.
Failure to observe this warning may result in injury.
• Do not modify the linear servomotor.
Failure to observe this warning may result in injury or damage to the product.
