I. Safety precautions
• 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
operation panel is attached to the unit.
This will result in failure. Please connect the USB cable to the 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.
• Mount the attached DC reactor (DCL) for VFAS3-4160KPC - 4280KPC.
If you do not mount the 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.
