2. Fire Prevention
CAUTION
 Inverter (Filterpack) must be installed on a nonflammable
wall without holes (so that nobody touches the inverter
heatsink on the rear side, etc.). Mounting it to or near
flammable material can cause a fire.
 If the inverter has become faulty, the inverter power must
be switched OFF. A continuous flow of large current could
cause a fire.
 When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may overheat due to damage
of the brake transistor and possibly cause a fire.
 Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
 Daily and periodic inspections must be performed as
instructed in the Instruction Manual. If the product is used
without receiving any inspection, it may cause a burst,
break, or fire.
3.Injury Prevention
CAUTION
 The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst,
damage, etc. may occur.
 The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
 Polarity must be correct. Otherwise burst, damage, etc.
may occur.
 While power is ON or for some time after power-OFF, do
not touch the inverter (Filterpack) since the inverter will be
extremely hot. Doing so can cause burns.
4. Additional Instructions
Also the following points must be noted to prevent an
accidental failure, injury, electric shock, etc.
(1) Transportation and Mounting
CAUTION
 The product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to injuries.
 Do not stack the boxes containing inverters higher than the
number recommended.
 The product must be installed to the position where withstands
the weight of the product according to the information in the
Instruction Manual.
 Do not install or operate the inverter (Filterpack) if it is damaged
or has parts missing.
 When carrying the inverter, do not hold it by the front cover or
setting dial; it may fall off or fail.
 Do not stand or rest heavy objects on the product.
 The inverter mounting orientation must be correct.
 Foreign conductive objects must be prevented from entering
the inverter (Filterpack). That includes screws and metal
fragments or other flammable substance such as oil.
 Because the inverter (Filterpack) is a precision instrument, do
not drop or subject it to impact.
 The inverter (Filterpack) must be used under the following
environment: Otherwise the inverter may be damaged.

(2) Wiring
 Do not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output
side. These devices on the inverter output side may be
overheated or burn out.
 The connection orientation of the output cables U, V, W to
the motor affects the rotation direction of the motor.
 IPM motor terminals (U, V, W) hold high-voltage while the
IPM motor is running even after the power is turned OFF.
Before wiring, the IPM motor must be confirmed to be
stopped. Otherwise you may get an electric shock.
 Never connect an IPM motor to the commercial power
supply. Applying the commercial power supply to input
terminals (U,V, W) of an IPM motor will burn the IPM motor.
The IPM motor must be connected with the output
terminals (U, V, W) of the inverter.
(3) Trial run
 Before starting operation, each parameter must be
confirmed and adjusted. A failure to do so may cause
some machines to make unexpected motions.
(4) Usage
 The IPM motor capacity must be same with the inverter
capacity.
 Do not use multiple IPM motors with one inverter.
 Any person must stay away from the equipment when the
retry function is set as it will restart suddenly after trip.
 Since pressing
on the function setting status, separate circuit and switch
that make an emergency stop (power OFF, mechanical
brake operation for emergency stop, etc.) must be
provided.
 OFF status of the start signal must be confirmed before
resetting the inverter fault. Resetting inverter alarm with
the start signal ON restarts the motor suddenly.
 Do not use an IPM motor in an application where a motor
is driven by its load and runs at a speed higher than the
maximum motor speed.
 A dedicated IPM motor must be used under IPM motor
control. Do not use a synchronous motor, induction
motor, or synchronous induction motor under IPM motor
control.
 The inverter must be used for three-phase induction
motors or the dedicated IPM motor.
Connection of any other electrical equipment to the
inverter output may damage the equipment.
 Do not modify the equipment.
 Do not perform parts removal which is not instructed in
this manual. Doing so may lead to fault or damage of the
product.
