2. Fire Prevention

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you have read through this Instruction Manual (Basic) and appended documents carefully and can use the equipment correctly. Do not use the inverter 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".
WARNING
Incorrect handling may cause hazardous conditions, resulting in death or severe injury.
CAUTION
Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.
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.
1. Electric Shock Prevention
WARNING
While power is ON or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.
Do not run the inverter with the front cover or wiring cover
Inverter 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.
Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing so could cause a fire.
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 since the inverter will be extremely hot. Doing so can cause burns.
CAUTION
CAUTION
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 wiring, inspection or switching EMC filter ON/OFF connector, 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, inspection or switching EMC filter ON/OFF connector shall 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 code (NEC section 250, IEC 536 class 1 and other applicable 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 fully competent to do the work.
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 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 with wet hands. You may
4. Additional Instructions
Also the following points must be noted to prevent an accidental failure, injury, electric shock, etc.
(1) Transportation and installation
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 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.
The inverter mounting orientation must be correct.
Foreign conductive bodies must be prevented to enter the
inverter. That includes screws and metal fragments or other flammable substance such as oil.
As the inverter is a precision instrument, do not drop or subject it to impact.
The inverter must be used under the following environment: Otherwise the inverter may be damaged.
Surrounding air temperature
Ambient humidity 90% RH or less (non-condensing) Storage temperature -20°C to +65°C

motor terminal, etc. right after powering off to prevent an electric shock.
*1
*2
A-1
(2) Wiring
Do not install a power factor correction capacitor, surge suppressor or 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.
(3) Test operation and adjustment
CAUTION
CAUTION
Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.
(4) Operation
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.
The inverter must be used for three-phase induction motors. 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 inverter.
WARNING
(5) Emergency stop
A safety backup such as an emergency brake must be provided to prevent hazardous condition to the machine and equipment in case of inverter failure.
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
CAUTION
CAUTION
Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.
(7) Disposing of the inverter
CAUTION
The inverter must be treated as industrial waste.
General instructions
Many of the diagrams and drawings in this Instruction Manual (basic) show the inverter without a cover or partially open for explanation. Never operate the inverter in this manner. The cover must be always reinstalled and the instruction in this Instruction Manual (basic) must be followed when operating the inverter.
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.
The effect of electromagnetic interference must be reduced by using a noise 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/ damage 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.
For prevention of damage due to static electricity, nearby metal must be touched before touching this product to eliminate static electricity from your body.

Reactor (FR-HAL, FR-HEL)
Reactors (option) should 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 (1000kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. For the 55K or less, remove the jumpers across terminals P/+-P1 to connect to the DC reactor.
(Refer to the chapter 2 of the Instruction Manual (applied) .)
RS-485 terminal block
The inverter can be connected with computers such as programmable controller. It supports Mitsubishi inverter protocol and Modbus-RTU (binary) protocol.
Inverter (FR-F700)
The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as possible within the permissible range. Especially when mounting the inverter inside an enclosure, take cautions of the surrounding air temperature. (Refer to page 7) 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 8) Refer to page 9 for the built-in EMC filter.
AC reactor (FR-HAL)

2.4.2 EMC filter

This inverter is equipped with a built-in EMC filter (capacitive filter) and common mode choke. The EMC filter is effective for reduction of air-propagated noise on the input side of the inverter. The EMC filter is factory-set to disable (OFF). To enable it, fit the EMC filter ON/OFF connector to the ON position. The input side common mode choke, built-in the 55K or less inverter, is always valid regardless of ON/OFF of the EMC filter ON/OFF connector.

· The power supply cables must be connected to R/L1, S/L2, T/L3. (Phase sequence needs not to be matched.) Never connect the power cable to the U, V, W of the inverter. Doing so will damage the inverter.
· Connect the motor to U, V, W. At this time, turning on the forward rotation switch (signal) rotates the motor in the counterclockwise direction when viewed from the motor shaft.
· When wiring the inverter main circuit conductor of the 250K or more, tighten a nut from the right side of the conductor. When wiring two wires, place wires on both sides of the conductor. (Refer to the drawing below.) For wiring, use bolts (nuts) provided with the inverter.

line voltage drop [V]=
3 × wire resistance[mΩ/m] × wiring distance[m] × current[A]
1000
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.
CAUTION
· Tighten the terminal screw to the specified torque. A screw that has been tighten too loosely can cause a short circuit or malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.
· Use crimping terminals with insulation sleeve to wire the power supply and motor.

(2) Notes on earthing (grounding)
• Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed (grounded). 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) A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.
• Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not use the screw in the casing, chassis, etc.)
• Use the thickest possible
14
, 15 and minimize the cable length. The earthing (grounding) point should be as near as possible to the inverter.
To be compliant with the EU Directive (Low Voltage Directive), earth (ground) the inverter according to
the instructions on page 155.
(3) Total wiring length
The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.

2) Connect the surge voltage suppression filter (FR-ASF-H) to the 55K or less and the sine wave filter (MT-BSL/BSC)
to the 75K or more on the inverter output side.
CAUTION
· 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 or fast response current limit function or a malfunction or fault of the equipment connected on the inverter output side. If fast-response current limit function malfunctions, disable this function. (For Pr.156 Stall prevention operation selection, refer to the chapter 4 of the Instruction Manual (applied).)
· For details of Pr. 72 PWM frequency selection , refer to the chapter 4 of the Instruction Manual (applied). (When using an optional sine
wave filter (MT-BSL/BSC) for the 75K or more, set "25" in Pr.72 (2.5kHz)).

Turn on the STF signal to start forward rotation and turn it off to stop.
Turn on the STR signal to start reverse rotation and turn it off to stop.
Turn on the STOP signal to self-hold the start signal. *2
Multi-speed can be selected according to the combination of RH, RM and RL signals.
Turn on the JOG signal to select Jog operation (initial setting) and turn on the start signal (STF or STR) to start Jog operation.
Turn on the RT signal to select second function. When the second function such as "second torque boost" and "second V/F (base frequency)" are set, turning on the RT signal selects these functions.
Turn on the MRS signal (20ms or more) to stop the inverter output. Use to shut off the inverter output when stopping the motor by electromagnetic brake.
Used to reset fault output provided when fault occurs. Turn on the RES signal for more than 0.1s, then turn it off. Initial setting is for reset always. By setting Pr.75, reset can be set to enabled only at fault occurrence. Inverter recovers about 1s after the reset is released.
Terminal 4 is valid only when the AU signal is turned on. (The frequency setting signal can be set between 0 and 20mADC.) Turning the AU signal on makes terminal 2 (voltage input) invalid.
AU terminal is used as PTC input terminal (thermal protection of the motor). When using it as PTC input terminal, set the AU/PTC switch to PTC.
When the CS signal is left on, the inverter restarts automatically at power restoration. Note that restart setting is necessary for this operation. In the initial setting, a restart is disabled.
(Refer to Pr. 57 Restart coasting time in the chapter 4 of the Instruction Manual (applied).)

2.4.6 Changing the control logic

The input signals are set to sink logic (SINK) when shipped from the factory. To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to the other position. (The output signals may be used in either the sink or source logic independently of the jumper connector position.)
1)Loosen the two installation screws in both ends of the control circuit terminal block. (These screws cannot be removed.) Pull down the terminal block from behind the control circuit terminals.
2)Change the jumper connector set to the sink logic (SINK) on the rear panel of the control circuit terminal block to source logic (SOURCE).
Jumper connector
3)Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix it with the mounting screws.
CAUTION
1. Make sure that the control circuit connector is fitted correctly.
2. While power is on, never disconnect the control circuit terminal block.

4) Sink logic and source logic
r
In sink logic, a signal switches on when a current flows from the corresponding signal input terminal.
Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.
In source logic, a signal switches on when a current flows into the corresponding signal input terminal.
Terminal PC is common to the contact input signals. Terminal SE is common to the open collector output signals.
