Read this manual and related documents before attempting to install, operate,
service or inspect this inverter.
Make sure that you have an understanding of the device, the safety information
and all precautions before starting use.
1. INSTALLATION
ATTENTION
●Install the unit on a non-combustible material such as metal.
Installing it on other material could lead to fires.
●Do not place the unit near flammable materials.
Doing so could lead to fires.
●Do not hold by the terminal cover during transportation.
Doing so could cause the unit to drop and lead to injuries.
●Do not allow foreign matter such as metal swarf enter the unit.
Entry of this type of matter could lead to fires.
●Install the unit according to the instruction manual on a place where the
weight can be withstood.
Failure to do so could lead to dropping of the unit and to injuries.
●Do not install or operate an inverter that is damaged or missing parts.
Doing so could lead to injuries.
CE Mark Conditions
VF-0 inverter meets overvoltage category II of the standard EN50178.
The inverter should be supplied with power from mains via a transformer
with at least basic insulation.
The complete machine has to comply to overvoltage category III of the
standard EN50178.
This inverter is not a self-contained operating unit according to the EMC
directive. Only after integrating the inverter into a machine including filters
can the complete system be evaluated with respect to electromagnetic
compatibility.

2. WIRING
ATTENTION
●Always confirm that the input power is OFF before starting wiring.
Failure to do so could lead to electric shocks or fires.
●Always connect the earth.
Failure to do so could lead to electric shocks or fires.
●Wiring work must be carried out by a qualified technician.
Failure to do so could lead to electric shocks or fires.
●Always install the unit before wiring.
Failure to do so could lead to electric shocks or fire.
ATTENTION
●Do not connect an AC power supply to the output terminals
(U, V, W).
Doing so could lead to injuries or fire.
●Confirm that the product's rated voltage and the AC power supply voltage
match.
Failure to do so could lead to injuries or fire.
●Tighten the terminal screws to the designated tightening torque.
Failure to do so could lead to fire.

3. OPERATION
ATTENTION
●Always close the terminal cover before turning the input power ON. Do not
open the terminal cover while the power is ON.
Doing so could lead to electric shock.
●Do not operate the switches with wet hands.
Doing so could lead to electric shock.
●Do not touch the inverter terminals when the inverter power is ON or even
when the inverter is stopped.
Doing so could lead to electric shock.
●The STOP button is not designed for emergency stop purposes. Prepare
a separate emergency stop button.
Failure to do so could lead to injury.
●Depending on the start mode and ride-through function settings, if the run
signal is on and the power is turned ON or the power is restored after a
power failure, the unit may start (restart) suddenly. Bear this in mind
before conducting maintenance.
(Design the machine so that personel safety can be ensured even if the
unit starts suddenly.)
Failure to do so could lead to injury.
●Depending on the start mode function setting, if the fault trip is reset with
the run signal present, the unit may restart suddenly.
(Reset the trip after ensuring personel safety.)
Failure to do so could lead to injury.
●When the retry function is used, the unit may automatically start (restart)
suddenly so do not approach the unit.
(Secure personal safety before using this function.)
Failure to do so could lead to injury

ATTENTION
●The heat sink fins and brake resistor (dedicated option) can reach high
temperatures, so allow to cool before touching.
Doing so could lead to burns.
●The inverter can be easily set to run from low speeds to high speeds.
Confirm the tolerable range of the motor and machine before starting
operation.
Failure to do so could lead to injury.
●Prepare holding brakes when required.
Failure to do so could lead to injury.
4. MAINTENANCE, INSPECTION AND PART REPLACEMENT
ATTENTION
●Wait at least five minutes after turning the input power OFF before starting
inspections.
Failure to do so could lead to electric shock.
●Maintenance, inspection and part replacement must be done by qualified
persons.
[Remove all metal personal belongings (watches, bracelets, etc.) before
starting the work.] (Use tools treated with insulation.)
Failure to do so could lead to electric shocks or injury.
ATTENTION
●Have an electrician periodically tighten the terminal screws.
Loosening of the terminal screws could lead to overheating or fire.
