Safety Precautions
These safety precautions are very important. Read them before performing any procedures such as storage and
transportation, installation, wiring, operation, maintenance and inspection, or disposal. Be sure to always
observe these precautions thoroughly.
WARNING
• If you have a pacemaker or any other electronic medical device, do not go near the magnetic way of
the linear servomotor.
Failure to observe this warning may result in the malfunction of the 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.)
• Before starting operation with a machine connected, make sure that an emergency stop can be
applied at any time.
Failure to observe this warning may result in injury or damage to the product.
• Never touch the linear servomotor or machinery during operation.
Failure to observe this warning may result in injury.
• Before wiring, install the SERVOPACK and the linear servomotor.
Failure to observe this warning may result in electric shock.
• Never touch the inside of the SERVOPACKs.
Failure to observe this warning may result in electric shock.
• Do not remove the cover of the power supply terminal while the power is ON.
Failure to observe this warning may result in electric shock.
• After the power is turned OFF or after a voltage resistance test, do not touch terminals while the
charge indicator is ON.
Residual voltage may cause electric shock.
• Follow the procedures and instructions provided in this manual for trial operation.
Failure to do so may result not only in faulty operation and damage to equipment, but also in personal injury.
• Do not remove the front cover, cables, connectors, or optional items from the upper front of the
SERVOPACK while the power is ON.
Failure to observe this warning may result in electric shock.
• Do not damage, press, exert excessive force on, or place heavy objects on the cables.
Failure to observe this warning may result in electric shock, stopping operation of the product, or fire.
• Provide an appropriate braking device on the machine side to ensure safety.
Failure to observe this warning may result in injury.
• Do not come close to the machine immediately after resetting an instantaneous power interruption.
The machine may restart unexpectedly. Take appropriate measures to ensure safety against an
unexpected restart.
Failure to observe this warning may result in injury.
• Connect the ground terminal according to local electrical codes (100 Ω or less for a SERVOPACK
with a 100 V, 200 V power supply, 10 Ω or less for a SERVOPACK with a 400 V power supply).
Improper grounding may result in electric shock or fire.
• Installation, disassembly, or repair must be performed only by authorized personnel.
Failure to observe this warning may result in electric shock or injury.
• The person who designs a system using the safety function (Hard Wire Base Block function) must
have full knowledge of the related safety standards and full understanding of the instructions in this
manual.
Failure to observe this warning may result in injury.
