• 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, regenerative unit connection terminal, and
motor main circuit cable terminals.
Failure to observe this caution may result in fire.
• Do not bundle or run power and signal lines together in the same duct. Keep power and sig-
nal lines separated by at least 300 mm. (11.81 in).
Failure to observe this caution may result in malfunction.
• Use twisted-pair shielded wires or multi-core twisted pair shielded wires for I/O signal cable
and encoder cable.
The maximum length is 3 m (118.11 in) for I/O signal cable and is 20 m (787.40 in) for
encoder cable.
• Do not touch the power terminals for five minutes after turning the power supply LED (PWR)
are OFF because high voltage may still remain in the SERVOPACK.
• 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
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 connector for power supply/regenerative
unit.
• Remove the connector for power supply/regenerative unit from the SERVOPACK prior to
wiring.
• Insert only one wire per terminal on the connector for power supply/regenerative unit.
• Make sure that the core wire is not electrically shorted to adjacent core wires.
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Always use the specified power supply voltage of single-phase 200 V to 230 V without con-
necting directly to the power supply of 400 V.
The SERVOPACK will be destroyed.
• Take appropriate measures to ensure that the input power supply is supplied within the
specified voltage fluctuation range.
An incorrect power supply may result in damage to the product.
• Install external breakers or other safety devices against short-circuit in external wiring.
Failure to observe this caution may result in fire.
• Take appropriate and sufficient countermeasures for each when installing systems in the fol-
lowing locations.
Failure to observe this caution may result in damage to the product.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields and magnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies, including power supply lines.
• Do not reverse the polarity of the battery when wiring with regenerative unit.
Failure to observe this caution may result in damage to the product.
