This section is specifically about safety matters

Do not attempt to install, op erate, maintain or inspect the
inverter until you have read through the Instruction Manual
(Basic) and appended documents carefully and can use the
equipment correctly. Do not use this product until you have
a full knowledge of the equipment, safety information and
instructions.
In this Instruction Manual (Basic), the safety instruction
levels are classified into "WARNING" and "CAUTION".

The level may even lead to a serious
consequence according to conditions. Both instruction
levels must be followed because these are important to
personal safety.

Incorrect handling may cause
hazardous conditions, resulting in
death or severe injury.

Incorrect handling may cause
hazardous conditions, resulting in
medium or slight inju ry, or may cause
only material damage.

1. Electric Shock Prevention

 While the inverter power is ON, do not remove t he front

cover or the wiring cover. Do not run the inverter with the
front cover or the wiring cover removed. Otherwise you
may access the exposed high voltage terminals or the
charging part of the circuitry and get an electric shock.

 Even if power is OFF, do not remove the front cover

except for wiring or periodic inspection. You may
accidentally touch the charged inverter circuits and get an
electric shock.

 Before wiring or inspection, power must be switched OFF.

To confirm that, LED indication of the operation panel
must be checked. (It must be OFF.) Any person who is
involved in wiring or insp ection shall wait for at le ast 10
minutes after the power supply has been switched OFF
and check that there are no residual voltage using a tester
or the like. The capacitor is charged with high voltage for
some time after power OFF, and it is dangerous.
This inverter must be earthed (grounded). Earthing



(grounding) must conform to the requirements of national
and local safety regulations and electrical code (NEC section
250, IEC 61140 class 1 and other appli cable standards). A
neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.

 Any person who is involved in wiring or inspection of this

equipment shall be fu lly competent to do the wo rk.

 The inverter must be installed before wiring. Otherwise

you may get an electric shock or be injured.

 Setting dial and key operations must be performed with

dry hands to prevent an electric shock. Otherwise you
may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy



loads or pinching. Otherwise you may get an electric shock.

 Do not change the cooling fan while power i s ON. It is

dangerous to change the cooling fan while power is ON.

 Do not touch the printed circuit board or handle the cables

with wet hands. Otherwise you may get an electric shock.

 When measuring the main circuit capacitor capacity, the

DC voltage is applied to the motor for 1s at powering OFF.
Never touch the motor terminal, etc. right after powering
OFF to prevent an electric shock.
IPM motor is a synchronous motor with high-performance



magnets embedded in the rotor. Motor terminals hold high
voltage while the motor is running even after the inverter
power is turned OFF. Before wiring or inspection, the motor
must be confirmed to be stopped. When the motor is driven by
the load in applications such as fan and blower, a low-voltage
manual contactor must be connected at the inverter's output
side, and wiring and inspection must be performed while the
contactor is open. Otherwise you may get an electric shock.

A-1

2. Fire Prevention

 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.
Be sure to perform daily and periodic inspections as specified



in the Instruction Manual. If a produ ct is used without any
inspection, a burst, breakage, or a fire may occur.

3.Injury Prevention

 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 (Filte rpack) since the inverte r (Filterpack)
will be extremely hot. Doi ng 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

 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 i t is

damaged or has missing parts.

 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 dr op or subject it to impact.

 The inverter (Filterpack) must be used under the following

environment conditions: Otherwise the inverter
(Filterpack) may be damaged.

1 Temperature applicable for a short time, e.g. in transit.
2 When installing the Filterpack of 11K or 15K on the rear

panel of the inverter, do not install on moving objects or
places which vibrates (exceeding 1.96m/s

2

).

 If halogen-based materials (fluorine, chlorine, bromine,

CAUTION

iodine, etc.) infiltrate into a Mitsubishi Electric product,
the product will be damaged. Halogen-based materials are
often included in fumigant, w hich is used to steriliz e or
disinfest wooden packag es. When packaging, prev ent
residual fumigant components from being infiltrated into
Mitsubishi Electric products, or use an alternative
sterilization or disinfection method (heat disinfection,
etc.) for packaging. Sterilization of disinfection of wooden
package should also be performed before packaging the
product.

(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. (The 0.75K inverter can be used with a one-rank
lower motor.)

 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 key may not stop output depending



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.

 The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is
recommended to install both an external thermal and PTC
thermistor for overheat protection.

 Do not use a magnetic contactor on the inverter input for

frequent starting/stopping of the inverter. Otherwise, the
life of the inverter decreases.

 The effect of electromagnetic interference must be

reduced by using an EMC filter or by other means.
Otherwise nearby electronic equipment may be affected.

 Appropriate measures must be taken to suppress

harmonics. Otherwise power supply harmonics from the
inverter may heat/damag e the power factor correction
capacitor and generator.

 When driving a 400V class motor by the inverter, the

motor must be an insulation-enhanced motor or measures
must be taken to suppress surge voltage. Surge voltage
attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor.
When parameter clear or all parameter clear is performed,



the required parameters must be set again before starting
operations because all parameters return to the initial value.

 The inverter can be easily set for high-speed operation.

Before changing its setting, the performances of the
motor and machine must be fully examined.

 Stop status cannot be hold by the inverter's brake

function. In addition to the inverter's brake function, a
holding device must be installed to ensure safety.

 Before running an inverter which had been stored for a

long period, inspection and test operation must be
performed.

 Static electricity in your body must be discharged before

you touch the product. Otherwise the product may be
damaged.

 Do not connect an IPM motor under the general-purpose

motor control settings (initial settings). Do not use a
general-purpose motor under the IPM motor control
setting. Doing so will cause a failure.

 In the system with an IPM motor, the inverter power m ust

be turned ON before closing the contacts of the contactor
at the output side.

(5) Emergency stop

 A safety backup such as an emergency brake must be

provided for devices or equipment in a system to prevent
hazardous conditions in case of failure of the inverter or
an external device controlling the inverter.

 When the breaker on the inverter input side trips, the

wiring must be checked for fault (short circuit), and
internal parts of the inverter for a damage, etc. The cause
of the trip must be identified and removed before turning
ON the power of the breaker.

 When any protective function is activated, appropriate

corrective action must be taken, and the inverter must be
reset before resuming operation.

(6) Maintenance, inspection and parts replacement

 Do not carry out a megger (insulation resistance) test on

the control circuit of the inverter. It will cause a failure.

(7) Disposal

 The inverter must be treated as industrial waste.

Reactors (option) must be used when
power harmonics measures are taken,
the power factor is to be improved or the
inverter is installed near a large power
supply system (500kVA or more). The

The breaker must be selected carefully
since an in-rush current flows in the
inverter at power on.

Install a noise filter (ferrite core)
to reduce the electromagnetic
noise generated from the
inverter. Effective in the range
from about 1MHz to 10MHz.
When more wires are passed
through, a more effective result
can be obtained. A wire should
be wound four turns or more.

* Not necessary if Filterpack (FR-BFP2) is used.

Earth (Ground)

To prevent an electric shock, always earth (ground)

The life of the inverter is influenced by surrounding ai r temperature. Use the product within the permissible surro unding
air temperature. This mu st be noted especiall y when the inverter is in stalled in an enclosure.

the Instruction Manual (Applied) .)

 Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main

circuit to protect them from noise. (Refer to page 10.)

 Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output

side. This will cause the inver ter to trip or the capacitor and surge s uppressor to be damaged. If an y of the above
devices are connected, immediately remove them.

 Electromagnetic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional EMC filter
(capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF EMC filter (ferrite core) to minimize interference.

( Refer to Chapter 3 of the Instruction Manual (Applied).)

 Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.
 An IPM motor cannot be driven by the commercial power supply.
 An IPM motor is a motor with permanent magnets embedded inside. High voltage is generated at the motor terminals

while the motor is running. Before closing the contactor at the output side, make sure that the inverter power is ON
and the motor is stopped.

 Connect the Filterpack terminals P and P1 to the inverter terminals of P/+ and P1, respectively. Improper connections

may damage the inverter.

2.3.5 Cables and wiring length

(1) Applicable cable size

Select the recommended cable size to ensure that a voltage drop will be 2% at maximum.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to
decrease especially at the output of a low frequency.
The following table indicates a selection example for the wiring length of 20m.



Tighten the terminal screw to the specified torque. A screw that has been tightened too loosely can cause a short circuit or
malfunction. A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.

 Use crimp terminals with insulation sleeve to wire the power supply and motor.

The line voltage drop can be calculated by the following formula:

Line voltage drop [V]=

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque

reduction) in the low speed range.

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor.

If that is the case, use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM

frequency selection according to wiring length. (

Use one dedicated IPM motor for one inverter. Multiple IPM motors cannot be connected to an inverter.

NOTE

 Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray

capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast-response current limit
function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function.
If malfunction of stall prevention function occurs, increase the stall level.

( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation selection in Chapter 4 of the Instruction

Manual (Applied).)

 When using the automatic restart after instantaneous power failure function for a general-purpose motor with the

wiring length longer than 100m, select "without frequency search" by setting Pr.162 = "1 or 11." (

to 0.75mm

NOTE

 Do not remove the shortening wires across the terminals S1 and SC and the terminals S2 and SC.

Removing either shortening wire disables the inverter operation.

(2) Wiring method

Wiring

Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. For a single wire, strip off the sheath of
the wire and apply directly. Insert the blade terminal or the single wire into a socket of the terminal.

1) Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur
among neighboring wires. If the length is too short, wires might come off.
Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.

2

Wire stripping length

2) Crimp the blade terminal.
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is
inappropriate, or the face is damaged.
