Do not use this product until you have a full knowledge of the equipment, safety information and instructions. In this Installation Guideline, the safety instruction levels are classified into "WARNING" and "CAUTION". WARNING Assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury. CAUTION Assumes that incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause physical damage only. Note that even the CAUTION level may lead to a serious consequence according to conditions. Please follow the instructions of both levels because they are important to personnel safety. 1. Electric Shock Prevention WARNING z While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock. z Do not run the inverter with the front cover or wiring cover removed. Otherwise, you may access the exposed highvoltage terminals or the charging part of the circuitry and get an electric shock. z 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. z Before starting wiring or inspection, switch off power, 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. z 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) z Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work. z Always install the inverter before wiring. Otherwise, you may get an electric shock or be injured. z Perform setting dial and key operations with dry hands to prevent an electric shock. Otherwise you may get an electric shock. z Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise, you may get an electric shock. z Do not change the cooling fan while power is on. It is dangerous to change the cooling fan while power is on. z Do not touch the printed circuit board with wet hands. Otherwise, you may get an electric shock. z 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. 2. Fire Prevention CAUTION z 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 combustible material can cause a fire. z If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire. z 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. z Do not connect a resistor directly to the DC terminals + and -. This could cause a fire. 3.Injury Prevention CAUTION z Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur. z Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur. z Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur. z While power is on or for some time after power-off, do not touch the inverter as they will be extremely hot. Doing so can cause burns. 4. Additional Instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc. (1) Transportation and mounting CAUTION z Transport the product using the correct method that corresponds to the weight.

A-1 D700_EC_Guideline_ib0600352ENG.book 2 ページ 2008年4月10日 木曜日 午後2時6分 (2) Wiring (5) Emergency stop CAUTION z 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. z The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor. (3) Trial run CAUTION z Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions. (4) Usage WARNING z When you have chosen the retry function, stay away from the equipment as it will restart suddenly after trip. z 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). z Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly. z The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may damage the equipment. z Do not modify the equipment. z Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the product. CAUTION z 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. z Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise, the life of the inverter decreases. z Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected. z Take measures to suppress harmonics. Otherwise power supply harmonics from the inverter may heat/damage the power factor correction capacitor and generator. z When a 400V 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. z When parameter clear or all parameter clear is performed, reset the required parameters before starting operations. Each parameter returns to the initial value. z The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor and machine. z In addition to the inverter’s holding function, install a holding device to ensure safety. z Before running an inverter which had been stored for a long period, always perform inspection and test operation. z For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from your body. A-2 CAUTION z Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails. z When the breaker on the inverter input 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. z When any protective function is activated, take the appropriate corrective action, then reset the inverter, and resume operation. (6) Maintenance, inspection and parts replacement CAUTION z Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure. (7) Disposal CAUTION z Treat as industrial waste. General instruction Many of the diagrams and drawings in this Installation Guideline show the inverter without a cover, or partially open. Never operate the inverter in this manner. Always replace the cover and follow this Installation Guideline when operating the inverter.

Do not earth (ground) them. 2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit). 3) Use two or more parallel micro-signal contacts or twin contacts to prevent contact faults when using contact inputs since the control circuit input signals are micro-currents. 4) Do not apply a voltage to the contact input terminals (e.g. STF) of the control Micro signal contacts Twin contacts circuit. 5) Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc. 6) It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals. If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running or the cables are run improperly, resulting in a fall off of the operation panel. 7) The maximum wiring length should be 30m. 9 D700_EC_Guideline_ib0600352ENG.book 10 ページ 2008年4月10日 木曜日 午後2時6分 PRECAUTIONS FOR USE OF THE INVERTER 4 PRECAUTIONS FOR USE OF THE INVERTER The FR-D700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items. (1) Use crimping terminals with insulation sleeve to wire the power supply and motor. (2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring. (3) After wiring, wire offcuts must not be left in the inverter. Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter. (4) Use cables of the size to make a voltage drop 2% 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. Refer to page 6 for the recommended wire sizes. (5) The overall wiring length should be 500m maximum. Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity of the wiring. Therefore, note the overall wiring length. (6) 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 capacitor type filter (for use in the input side only) or FR-BSF01 common mode filter to minimize interference. (7) Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, immediately remove them. When using capacitor type filter (FR-BIF) for single-phase power supply specification, make sure of secure insulation of T-phase, and connect to the input side of the inverter. (8) Before starting wiring or other work after the inverter is operated, 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. (9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules. y Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter modules. y Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on. Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc. (10) Do not use the inverter input side magnetic contactor to start/stop the inverter. Always use the start signal (turn on/off terminals STF, STR-PC) to start/stop the inverter. (11) Across + and PR terminals, connect only an external regenerative brake discharging resistor. The brake resistor can not be connected to the FR-D720S-008 and 014. Do not connect a mechanical brake. The brake resistor can not be connected to the FR-D720S-008 and 014. Leave terminals + and PR open. Also, never short between + and PR. 10 D700_EC_Guideline_ib0600352ENG.book 11 ページ 2008年4月10日 木曜日 午後2時6分 PRECAUTIONS FOR USE OF THE INVERTER (12) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits. Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short terminals 10-5. (13) Provide electrical and mechanical interlocks for MC1 and MC2 MC1 which are used for bypass operation. When the wiring is Interlock incorrect and if there is a bypass operation circuit as shown Power R/L1 U IM supply right, the inverter will be damaged when the power supply is S/L2 V MC2 T/L3 W connected to the inverter U, V, W terminals, due to arcs Undesirable current Inverter generated at the time of switch-over or chattering caused by a sequence error. (14) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the inverter's input side and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored. (15) Instructions for overload operation When performing operation of frequent start/stop of the inverter, rise/fall in the temperature of the transistor element of the inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing current at locked condition, starting current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger in capacity). (16) Make sure that the specifications and rating match the system requirements. (17) When the motor speed is unstable, due to change in the frequency setting signal caused by electromagnetic noises from the inverter, take the following measures when applying the motor speed by the analog signal. y Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them. y Run signal cables as far away as possible from power cables (inverter I/O cables). y Use shield cables as signal cables. y Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK). 11 D700_EC_Guideline_ib0600352ENG.book 12 ページ 2008年4月10日 木曜日 午後2時6分 FAILSAFE OF THE SYSTEM WHICH USES THE INVERTER 5 FAILSAFE OF THE SYSTEM WHICH USES THE INVERTER When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails. (1) Interlock method which uses the inverter status output signals By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be detected. No Interlock Method Check Method Used Signals 1) Inverter protective function operation Operation check of an alarm contact Circuit error detection by negative logic Fault output signal (ALM signal) 2) Inverter running status Operation ready signal check Operation ready signal (RY signal) 3) Inverter running status Logic check of the start signal and running signal 4) Inverter running status Logic check of the start signal and output current Start signal (STF signal, STR signal) Running signal (RUN signal) Start signal (STF signal, STR signal) Output current detection signal (Y12 signal) Refer to Page Refer to the chapter 4 of the Instruction Manual (applied)). Refer to the chapter 4 of the Instruction Manual (applied)). Refer to the chapter 4 of the Instruction Manual (applied)). Refer to the chapter 4 of the Instruction Manual (applied)). (2) Backup method outside the inverter Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure status of the inverter itself. For example, even if the interlock is provided using the inverter fault output signal, start signal and RUN signal output, there is a case where a fault output signal is not output and RUN signal is kept output even if an inverter fault occurs. Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the backup system such as checking up as below according to the level of importance of the system. 1) Start signal and actual operation check Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to the inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is recommended to check the three-phase current when using the current detector. 2) Command speed and actual operation check Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command and detected speed of the speed detector.

If the fault does not correspond to any of the following faults or if you have any other problem, please contact your sales representative. z Retention of fault output signal...When the magnetic contactor (MC) provided on the input side of the inverter is opened when a fault occurs, the inverter's control power will be lost and the fault output will not be held. z Fault or alarm indication ..........When a fault or alarm occurs, the operation panel display automatically switches to the fault or alarm indication. z Resetting method ....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter cannot restart. z When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation. Not doing so may lead to the inverter fault and damage. Inverter fault or alarm indications are roughly divided as below. (1) Error message A message regarding operational fault and setting fault by the operation panel and parameter unit (FR-PU04 /FR-PU07) is displayed. The inverter does not trip. (2) Warnings The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will lead to a fault. (3) Alarm The inverter does not trip. You can also output an alarm signal by making parameter setting. (4) Fault When a fault occurs, the inverter trips and a fault signal is output. 7.1 Reset method of protective function (1) Resetting the inverter The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.

Therefore, we understand that the EMC Directive does not apply directly to transistorized inverters. For this reason, we do not place the CE mark on the transistorized inverters. (The CE mark is placed on inverters in accordance with the Low Voltage Directive.) CEMEP 2) Compliance We understand that the general-purpose inverters are not covered directly by the EMC Directive. However, the EMC Directive applies to machines/equipment into which inverters have been incorporated, and these machines and equipment must carry the CE marks. EMC Installation Guidelines BCN-A21041-202 3) Outline of installation method Install an inverter using the following methods: ∗ Use the inverter with an European Standard-compliant noise filter. ∗ For wiring between the inverter and motor, use shielded cables or run them in a metal piping and ground the cables on the inverter and motor sides with the shortest possible distance. ∗ Insert a common mode filter and ferrite core into the power and control lines as required. Full information including the European Standard-compliant noise filter specifications are written in the technical information "EMC Installation Guidelines" (BCN-A21041-202). Please contact your sales representative. (2) Low Voltage Directive We have self-confirmed our inverters as products compliant to the Low Voltage Directive (Conforming standard EN 618005-1) and place the CE mark on the inverters. Outline of instructions ∗ Do not use an earth leakage circuit breaker as an electric shock protector without connecting the equipment to the earth. Connect the equipment to the earth securely. ∗ Wire the earth (ground) terminal independently. (Do not connect two or more cables to one terminal.) ∗ Use the cable sizes on page 6 under the following conditions. ySurrounding air temperature: 40°C maximum If conditions are different from above, select appropriate wire according to EN60204 ANNEX C TABLE 5. ∗ When tightening the screw, be careful not to damage the threads. For use as a product compliant with the Low Voltage Directive, use PVC cable on page 6. ∗ Use the moulded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard. ∗ When using an earth leakage circuit breaker, use a residual current operated protective device (RCD) of type B (breaker which can detect both AC and DC). If not, provide double or reinforced insulation between the inverter and other equipment, or put a transformer between the main power supply and inverter. ∗ Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) condition of the power supply), overvoltage category III (usable with the earthed-neutral system power supply, 400V class only) specified in IEC664. yTo use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher. 20 D700_EC_Guideline_ib0600352ENG.book 21 ページ 2008年4月10日 木曜日 午後2時6分 yTo use the inverter outside of an enclosure in the environment of pollution degree 2, fix a fan cover with fan cover fixing screws enclosed.
