Manufacturers and owners of the machine on which a FR-D700 SC inverter is used are responsible for obtaining and observing
all applicable safety regulations and rules.
It is imperative that the notices, in particular the test notices of the manuals be observed.The tests must be carried out by specialised personnel or specially qualified and authorised personnel and must be recorded
and documented to ensure that the tests can be reconstructed and retraced at any time by third parties.
3.1 Electric Shock Prevention
While power is ON or when the inverter is running, do not open the front cover or wiring cover. Otherwise you may get an electric
Do not run the inverter with the front 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 access the charged inverter circuits 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 (grounded). Earthing (Grounding) must conform to the requirements of national and local safety
regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards) Use a neutral-point earthed (grounded) power supply for 400 V class inverter in compliance with EN standard.
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.If your application requires by installation standards an RCD (residual current device) as up stream protection please select
according to DIN VDE 0100-530 as following: Single phase inverter type A or B Three phase inverter only type B (Additional instructions on the use of a residual current device are contained on page 27.)
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 not touch the printed circuit board or handle the cables with wet hands. You may get an electric shock.When measuring the main circuit capacitor capacity, the DC voltage is applied to the motor for 1 s at powering off. Never touch
the motor terminal, etc. right after powering off to prevent an electric shock.
shock.
3.2 Fire Prevention
Install the inverter on a nonflammable wall without holes (so that nobody can touch 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, switch off the inverter power. A continuous flow of large current could cause a fire.When using a brake resistor, make up a sequence that will turn off power when an alarm signal is output. Otherwise, the brake
resistor may excessively overheat due to damage of the brake transistor and such, causing 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.
3.3 Injury Prevention
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.While power is on or for some time after power-off, do not touch the inverter as it is hot and you may get burnt.

4.1 Transportation and Installation
Transport the product using the correct method that corresponds to the weight. Failure to observe this could lead to injuries.Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the instruction manual.
Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.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.Check the inverter mounting orientation is correct.Prevent other conductive bodies such as screws and metal fragments or other flammable substance such as oil from entering
the inverter.
As the inverter is a precision instrument, do not drop or subject it to impact.Use the inverter under the following environmental conditions. Otherwise, the inverter may be damaged.
Temperature applicable for a short time, e.g. in transit.
4.2 Wiring
Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not
approved from Mitsubishi Electric.
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.
4.3 Test Operation and Adjustment
Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions.
4.4 Operation
When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
Since pressing key may not stop output depending on the function setting status, provide a circuit and switch separately
to make an emergency stop (power off, mechanical brake operation for emergency stop, etc).
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 these connections if there is an error in the communications system or the data line. In configurations like this it is thus essential 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
CAUTION
CAUTION
CAUTION
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.
Use a noise filter to reduce the effect of electromagnetic interference and follow the accepted EMC procedures for proper
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.When a 400 V class motor is inverter-driven, please use an insulation-enhanced motor or measures taken to suppress surge
voltages. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.
When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter
returns to the initial value.
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.
If you are installing the inverter to drive a three-phase device while you are contracted for lighting and power service, consult
your electric power supplier.
4.5 Emergency Stop
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 the inverter, 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.
4.6 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.
It is recommended to make the following checks periodically:
Check for loose screws in the terminal block. Retighten any loose screws.Check for dust accumulation on the inverter. Clean the heat sink and the cooling fan of the inverter.Check for unusual noise generated by the inverter. Retighten installation screw.Check for the operation condition. Keep the operation condition of inverter as written in the manual.
4.7 Disposal of the Inverter
Disposal of unusable or irreparable devices should always occur in accordance with the applicable country-specific waste-
disposal regulations (e.g. European Waste Code 16 02 14).
