ight incur electric shock and/or fire. After installing the main body, carry out wiring. ........... p. 51 Otherwise, there is a danger of electric shock and/or injury. WARNING zt\Azt\A A AAAA 12 CAUTION A A A Make sure that the input voltage is: Single/Three phase 200 to 240V 50/60Hz (Up to ) Three phase 200 to 240V 50/60Hz (Abore ) Three phase 380 to 460V 50/60Hz Be sure not to input a single phase to a 3 phase type Otherwise,there is a danger of fire. Be sure not to connect AC power supply to the output terminals (U, V, W). Otherwise, there is a danger of injury and/or fire. .52 .52 .52 INPUT OUTPUT Note) (LI) (N) L1 L2 L3 (T1) (T2) (T3) U V W Note: L1,N : Single phase 200 to 240V 50/60Hz L1,L2,L3: Three phase 200 to 240V 50/60Hz Three phase 380 to 460V 50/60Hz Power supply A Fasten the screws with the specified fastening torque. Check so that ............................. there is no loosening of screws. Otherwise, there is a danger of fire. /f\ Remarks for using earth leakage circuit breakers in the mains supply: Frequency inverters with CEfilters(RFIfilter) and screened motor cables have a higher leakage current against earth. Especially in the moment of switching on this can cause unintentional triggerings of earth leakage circuit breakers. Because of the rectifier on the input side of the inverter there is the possibility to stall the switchoff function through amounts of DCcurrent. The following should be observed: Only short timeinvariant and pulse currentsensitive earth leakage circuit breakers with higher trigger current should be used. Other ponents should be secured with separate earth leakage circuit breakers. Earth leakage circuit breakers in front of an inverter are not an absolute protection against direct touching. /f\ Be sure to set the fuse(s) (the same phase as the main power supply) ........................... in the operation circuit. Otherwise, there is a danger of fire. /1\ As for motor leads, earth leakage breakers and electromagic ......... contactors, be sure to use the equivalent ones with the specified capacity (rated). Otherwise, there is a danger of fire. 13 3. Control and operation /!\ WARNING /f\ Be sure to turn on the input power supply after closing the front .................................. p. 61 case. While being energized, be sure not to open the front case. Otherwise, there is a danger of electric shock. /K Be sure not to operate the switches with wet hands. ........... p. 61 Otherwise, there is a danger of electric shock. /|\ While the inverter is energized, be sure not to touch the inverter .................................. p. 61 terminals even during stoppage. Otherwise, there is a danger of electric shock. /|\ If the retry mode is selected, it may suddenly restart during the trip ............................. p. 61, stop. Be sure not to approach the machine. (Be sure to design the p. 811 machine so that personnel safety will be secured even if it restarts.) Otherwise, there is a danger of injury. /f\ Even if the power supply is cut for a short period of time, it may ................................. p. 61 restart operation after the power supply is recovered if the operation mand is given. If it may incur danger to personnel, be sure to make a circuit so that it will not restart after power recovery. Otherwise, there is a danger of injury. /|\ The Stop Key is effective only when the function is set. Be sure to .............................. p. 61 prepare the Key separately from the emergency stop. Otherwise, there is a danger of injury. /K After the operation mand is given, if the alarm reset is ........... p. 61 conducted, it will restart suddenly. Be sure to set the alarm reset p. 712 after checking the operation mand is off. Otherwise, there is a danger of injury. /|\ Be sure not to touch the inside of the energized inverter or to put a ............................. p. 61 bar into it. Otherwise, there is a danger of electric shock and/or fire. /1\ When the power is turned on when the running mand is on, the .......................... p. 74 motor starts rotation and it is dangerous. Before turning the power on, confirm that the running mand is not on. /t\ When the Stop key function is ineffective, pressing the Stop key ............................... p. 812 does not cancel the stop and trip. Be sure to provide an emergency stop switch separately. When the operation mand destination is a digital operator, this selection is ineffective. 14 CAUTION A A A Zh 62 Cooling fin will have high temperature. ........... p* 62 Be sure not to touch them. Otherwise, there is a danger of getting burned. Low to high speed operation of the inverter can be easily set. Be sure ........................................................ p. 62 to operate it after checking the tolerance of the motor and machine. Otherwise, there is a danger of injury. If a motor is operated at a frequency higher than standard setting ...................... value(50Hz/60Hz),be sure to check the speeds of the motor and the machine with each manufacturer, and after getting their consent, operate them. Otherwise, there is a danger of machine breakage. Check the following before and during the test run. ........... Otherwise, there is a danger of machine breakage. Was the shortcut bar between P1 and P(+) removed? Was the direction of the motor correct? Was the inverter tripped during acceleration or deceleration? Were the rpm and frequency meter correct? Were there any abnormal motor vibrations or noise? 64 4. Maintenance, inspection and part replacement /!\ WARNING A After a lapse of more than 5 minutes after turning off the input power ................................ P. 111。
