CAUTION
• Never use the product 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 or malfunction.
• Do not cover the inlet or outlet ports 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 con-
verter 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.
CAUTION
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Do not connect a commercial power supply to the U, V, or W terminals for
the servomotor connection.
Failure to observe this caution may result in injury or fire.
• Securely connect the main circuit terminals.
Failure to observe this caution may result in fire.
• Do not bundle or run the main circuit cables together with the I/O signal
cables or the encoder cables in the same duct. Keep them separated by at
least 30 cm.
Failure to do so may result in malfunction.
• Use shielded twisted-pair wires or multi-core shielded twisted-pair wires for
I/O signal cables and encoder cables.
• Use the bus bars that are included with the converter, and connect the P
and N terminals on the SERVOPACK and converter securely.
• The maximum cable length is 3 m for I/O signal cables, 50 m for connection
cables for servomotor main circuit or encoder cables, and 10 m for control
power supply cables to 400-V converters (+24 V, 0 V).
• Do not touch the power terminals while discharging the main circuit’s
capacitor, because high voltage may still remain in the SERVOPACK and
the converter. For details on the charging time of the main circuit’s capaci-
tor, refer to 3.2 Discharging Time of the Main Circuit’s Capacitor.
Before starting to do wiring or inspections, confirm that the power has been com-
pletely discharged (charge indicator: OFF) by using a tester to measure the voltage
between the P and N terminals for DC power.
