• Never use the products in an environment subject to water, corrosive gases, inflammable gases, or
combustibles.
Failure to observe this caution may result in electric shock or fire.
• Do not step on or place a heavy object on the product.
Failure to observe this caution may result in injury.
• Do not cover the inlet or outlet parts and prevent any foreign objects from entering the product.
Failure to observe this caution may cause internal elements to deteriorate resulting in malfunction or fire.
• Be sure to install the product in the correct direction.
Failure to observe this caution may result in malfunction.
• Provide the specified clearances between the SERVOPACK and the control panel or with other devices.
Failure to observe this caution may result in fire or malfunction.
• Do not apply any strong impact.
Failure to observe this caution may result in malfunction.
• Do not connect a three-phase power supply to the U, V, or W output terminals.
Failure to observe this caution may result in injury or fire.
• Securely connect the power supply terminals and motor output terminals.
Failure to observe this caution may result in fire.
• Do not apply stress to connectors.
• Do not bundle or run power and signal lines together in the same duct. Keep power and signal lines
separated by at least 30 cm.
Failure to observe this caution may result in malfunction.
• Use twisted-pair shielded wires or multi-core twisted pair shielded wires for signal and encoder (PG)
feedback lines.
The maximum length is 3 m for reference input lines and is 20 m for PG feedback lines.
• Do not touch the power terminals for five minutes after turning power OFF because high voltage may still
remain in the SERVOPACK.
Make sure the charge indicator is turned OFF first before starting an inspection.
• Avoid frequently turning power ON and OFF. Do not turn power ON or OFF more than once per minute.
Since the SERVOPACK has a capacitor in the power supply, a high charging current flows for 0.2 seconds when
power is turned ON. Frequently turning power ON and OFF causes main power devices such as capacitors and fuses
to deteriorate, resulting in unexpected problems.
• Observe the following precautions when wiring main circuit terminal blocks.
• Remove the terminal block from the SERVOPACK prior to wiring.
• Insert only one wire per terminal on the terminal block.
• Make sure that the core wire is not electrically shorted to adjacent core wires.
• Do not connect the SERVOPACK for 100 V and 200 V directly to a voltage of 400 V.
The SERVOPACK will be destroyed.
