Warnings for UL/cUL Marking
• Do not connect or disconnect wiring, or perform signal checks while the power
supply is turned ON.
• The Inverter internal capacitor is still charged even after the power supply is turned
OFF. To prevent electric shock, disconnect all power before servicing the Inverter.
Then, wait at least one minute after the power supply is disconnected and all
indicators are OFF.
• Do not perform a withstand voltage test on any part of the Inverter. This electronic
equipment uses semiconductors and is vulnerable to high voltage.
• Do not remove the Digital Operator or the blank cover unless the power supply is
turned OFF. Never touch the printed control board (PCB) while the power supply is
turned ON.
•The Inverter is not suitable for use on a circuit capable of delivering more than
18,000 RMS symmetrical amperes, 250volts maximum (200V class units) or
18,000 RMS symmetrical amperes, 480volts maximum (400V class units).
CAUTION (Ref. page)
Low voltage wires shall be wired with Class I Wiring. . . . . . . . . . . . . . . . 22

CAUTION (Ref. page)
• Verify that the inverter rated voltage coincides with the
AC power supply voltage.
Failure to observe this caution can result in personal injury
or fire.
• Do not perform a withstand voltage test of the inverter
It may cause semi-conductor elements to be damaged.
• To connect a braking resistor, braking resistor unit or braking
unit, follow the procedures described in this manual.
Improper connection may cause a fire.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25
• Make sure to tighten terminal screws of the main circuit
and the control circuit.

OPERATION
WARNING (Ref. page)
• Only turn ON the input power supply after replacing the
digital operator/blank cover (optional).
Do not remove the digital operator or the covers while
current is flowing.
Failure to observe this warning can result in electric shock.
• Never operate the digital operator or dip switches when
your hand is wet.
Failure to observe this warning can result in electric shock.
• Never touch the terminals while current is flowing, even
during inverter stopping.
Failure to observe this warning can result in electric shock.
• When the fault retry function is selected, stand clear of
the inverter or the load, since it may restart suddenly
after being stopped.
(Construct machine system, so as to assure safety for personnel,
even if the inverter should restart.) Failure to observe this
warning can result in personal injury.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60
• When continuous operation after power recovery is selected,
