This instruction manual provides instructions for advanced use of the FR-D700 series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this instruction manual to use the equipment to its optimum. Safety instructions Do not attempt to install, operate, maintain or inspect the inverter until you have read through this instruction manual carefully and can use the equipment correctly. Do not use the inverter un- til you have a full knowledge of the equipment, safety information and instructions. In this in- struction manual, the safety instruction levels are classified into "WARNING" and "CAUTION". P WARNING: Assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury. E CAUTION: Assumes that incorrect handling may cause hazardous conditions, resulting in medi- um 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 strictly the instructions of both levels because they are important to personnel safety. FR-D700 EC I Electric Shock Prevention P 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 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. 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) Use a neutral-point earthed (grounded) power supply for 400V 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 require by installation standards a 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 ● 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 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 1s at powering off. Never touch the motor terminal, etc. right after powering off to prevent an electric shock. II Fire Prevention E CAUTION: ● Mount the inverter to incombustible material. 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. ● 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 +, –. 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 E CAUTION: ● Apply only the voltage specified in the instruction manual to each terminal. Other- wise, 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. FR-D700 EC III Additional Instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc. Transport und Installation E CAUTION: ● 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. Operating Condition Specifications Ambient temperature −10°C to +50°C (non-freezing) Ambient humidity 90% RH or less (non-condensing) Storage temperature −20°C to +65°C (cid:2) Atmosphere Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt) Maximum 1000m above sea level for standard operation. After that derate by 3% for Altitude every extra 500m up to 2500m (91%) Vibration 5.9m/s2 or less at 10 to 55Hz (directions of X, Y, Z axes) (cid:2) Temperature applicable for a short time, e.g. in transit. Wiring E 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. IV Trial run E CAUTION: ● Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions. Operation P WARNING: ● When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop. ● Since pressing STOP/RESET 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 load used should be a three-phase induction motor only. 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. FR-D700 EC V E 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. Oth- erwise 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 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. Emergency stop E 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 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. Maintenance, inspection and parts replacement E CAUTION: ● Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure. VI
