• Do not attach devices with built-in capacitors (such as noise reduction filters or surge absorbers) to the
output terminals (motor side). Heat rises up and this could cause a fire.
• Do not switch only one of two grounding capacitor switch screws in the same form. The inverter will
have failure due to insufficient switching. Please switch two grounding capacitor switch screws in the
same form.
• Do not detach the operation panel from the unit when the power is ON. This will result in failure. Please
detach the operation panel after turning the power off.
• When you connect a USB cable to the operation panel, do not perform the connection while the
Prohibited
operation panel is attached to the unit. This will result in failure. Please connect the USB cable to the
EN
operation panel after detaching the operation panel from the unit.
• Do not connect Ethernet to the RS485 communication connector. Erroneous connection will result in
failure.
• Do not connect RS485 communication to the Ethernet connector. Erroneous connection will result in
failure.

• Verify that the power is OFF before detaching the front cover. If you detach the front cover while the
power is ON, this will result in electric shock or other injury.
• Mount the front cover after wiring. If you turn the power on without attaching the front cover, this will
result in electric shock or other injury. Please be careful that if you press too hard the front cover by a
screwdriver for attachment, it will damage the inverter unit.
Mandatory
• Mount the attached DC reactor (DCL) for VFAS3-4160KPC - 4280KPC. If you do not mount the
action
6 attached DC reactor (DCL), it will result in failure. Mount the DC reactor (DCL) between [PA/+] and [PO].
• Supply AC power supply to cooling fans if you use VFAS3-4160KPC - 4280KPC with DC input. If you do
not supply AC power supply, the cooling fans do not operate, and this will result in overheat trip.
■ Operations
6
• Do not touch terminals when the inverter's power is on even if the motor is stopped. Touching the
terminals while voltage is applied will result in electric shock.
• Do not touch switches when the hands are wet and do not try to clean the inverter with a damp cloth.
Prohibited
This will result in electric shock.
• Turn the power on only after mounting the front cover. When you use the inverter housed in the cabinet
6
with the front cover removed, always close the cabinet doors first and then turn the power on. If you turn
the power on with the front cover or the cabinet doors open, this will result in electric shock.
• Make sure to set the setup menu correctly. If you set the setup menu incorrectly, this will damage the
inverter or cause the inverter to perform unexpected movement.
Mandatory • Make sure to set the parameter correctly. If you set the parameter incorrectly, this will damage the
action inverter or cause the inverter to perform unexpected movement. When you write the parameter in the
inverter via a parameter writer, please transmit correct data.
6
• Make sure that operation instructions are off before resetting the inverter after malfunction. If the inverter
is reset while the operation instructions are on, the motor will restart suddenly, resulting in injury.
6
• Observe all allowable operating ranges of motors and machines in use. Not observing these ranges will
result in damage to motors and machines and injury. Please use motors and machines within their
respective allowable operating ranges by referring to their respective instruction manuals.
Prohibited
• Use the inverter that conforms to specifications of the power supply and the three-phase motor to be
operated. If you use the inappropriate inverter, not only will the three-phase motor not rotate correctly,
but it will cause serious accidents such as overheating and burning out.
6
• Take countermeasures against leakage current. The leakage current through the stray capacitance of
the input/output power wires of inverter and motor can affect peripheral devices. In that case, please
Mandatory
take countermeasures such as reducing the carrier frequency or shortening the length of input/output
action
power wires. When the total wire length (total length between an inverter and motors) is more than
100m, if the trip occurs with the motor no-load current, make enough space between phase wires or
insert the filter (MSF: motor-end surge voltage suppression filter).

*Read the Safety precautions of the instruction manual (CD-ROM) for maintenance, inspection and disposal.
