and get an electric shock.
Before starting wiring or inspection, check to make sure that the operation panel indicator is off, wait for at least 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. Earthing must conform to the requirements of national and local safety regulations and electrical codes.
(JIS, NEC section 250, IEC 536 class 1 and other applicable standards)
Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.
Always install the inverter before wiring. Otherwise, you may get an electric shock or be injured.
Perform setting dial and key operations 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 replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on.
Do no
t touch the printed circuit board w ith w et hands. You may get an electric shock.
Fire Prevention
CAUTION
Mount the inverter to incombustible material. Mounting it to or near combustible material can cause a fire.
If the inverter has become faulty, switch off the inverter power.
A continuous flow of large current could cause a fire.
Do not connect a resistor directly to the DC terminals P, N. This could cause a fire and destroy the inverter. The surface temperature of
braking resistors can far exceed 100°C for brief periods. Make sure that there is adequate protection against accidental contact and a safe
distance is maintained to other units and system parts.
Injury Prevention
CAUTION
Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur.
Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur.
Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur.

Wiring
CAUTION
Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved
from Mitsubishi.
The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V,
W) is maintained.
Test operation and adjustment
CAUTION
Before starting operation, confirm and adjust the parameters. A fa ilure to do so may cause some machines to make unexpected
motions.
Operation
WARNING
When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
The key is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately.
Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
The inverter can be started and stopped via the serial port communications link or the field bus. However, please note that depending
on the settings of the communications parameters it may not be possible to stop the system via t hese c onnectio ns if there is an er ror
in the communications system or the data line. In configurations like this it is thus ess ential to install additional safety hardware that
makes it possible to stop the system in an emergency (e.g. controller inhibit via control signal, external motor contactor etc). Clear and
unambiguous warnings about this must be posted on site for the operating and service staff.
The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may
damage the inverter as well as 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 inverter.
CAUTION
The electronic thermal relay function does not guarantee protection of the motor from overheating.
Do not use a magnetic contactor on the inverter input for frequent starting/st opping of the inverter.
Use a noise filter to reduce the effect of electromagnetic interference and follow the accepted EMC procedures for p roper installation
of frequency inverters. Otherwise nearby electronic equipment may be affected.
Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators.
Use a motor designed for inverter operation. (The stress for motor windings is bigger than in line power supply).
When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter returns
to the ini tial valu e.
The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor and
machine.
The DC braking function of the frequency inverter is not designed to continuously hold a load. Use an electro-mechanical holding
brake on the motor for this purpose.
Before running an inverter which had been stored for a long period, always perform inspection and test operation.
For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from
your body.
Emergency stop
CAUTION
Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the
inverter fails.
When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of th
etc. Identify the cause of the trip, then remove the cause and power on the breaker.
When the protective function is activated (i. e. the frequency inverter switches off with an error message), take the corresponding
corrective action as described in the inverter manual, then reset the inverter, and resume operation.
Maintenance, inspection and parts replacement
e inverter,
CAUTION
Do not carry out a megger (insulation resistance) test on the control circuit of the inverter.
Disposing of the inverter
CAUTION
Treat as industrial waste.
