INSTALLATION CAUTION /|\ Be sure to install the unit on flame resistant material such as metal. Otherwise, there is a danger of fire. /|\ Be sure not to place anything inflammable in the vicinity. Otherwise, there is a danger of fire. Be sure not to let the foreign matter enter such as cut wire refuse, spatter from welding, iron refuse, wire, dust, etc. Otherwise, there is a danger of fire. Be sure to install it in a place which can bear the weight according to the specifications in the text (4. Installation). Otherwise, it may fall and there is a danger of injury. /K Be sure to install the unit on a perpendicular wall which is not subject to vibration. Otherwise, it may fall and there is a danger of injury. /|\ Be sure to install the unit with opening the front case and tighten the mounting screw ,it may fall and there is a danger of injury. /K Be sure not to install and operate an inverter which is damaged or parts of which are missing. Otherwise, there is a danger of injury. /|\ Be sure to install it in a room which is not exposed to direct sunlight and is well ventilated. Avoid environments which tend to be high in temperature, high in humidity or to have dew condensation, as well as places with dust, corrosive gas, explosive gas, inflammable gas, grindingfluid mist, salt damage, etc. Otherwise, there is a danger of fire. 41 Inverter should be mounted vertically on noflamable wall to prevent from over heating and fire. Make sure following clearance arround the inverter to keep cooling air flow. Foreign object should not be dropped into the equipment especially conductive chips,which may cause not only mulfunction and damage but also electrical and fire hazard. NOTE: Install the inverter vertically. Do not install it on the floor or horizontally. /h CAUTION Be sure that the wall surface is a nonflammable material, such as steel plate. Cover all ventilation holes on the inverter during installation to prevent from any foreign objects dropped into the equipment. Be sure to remove those covers before start operation . Top cover Ventilation holes (Both sides) Be sure to check the ambient temperature 10 to 40176。 C . In case of 50176。 C, set the carrier frequency 2 kHz or less and derate output current 80% or less. _____________________________________________________________________________________ Higher ambient temperature cause shorter equipment life. If there are some hot equipment near the inverter, keep it away from inverter as far as possible. When the inverter is installed in a cubicle and/or a box, temperature around inverter should be kept as above rating. Consider ventilation and clearance around the inverter. For safety reason,front cover should be closed and don’ t open it during operation. For safety requirement, the end application must be in accordance with BS EN602041. 42 5. WIRING /!\ WARNING /K Use 60/75176。 C Cu wire only or equivalent. A\ Open Type Equipment. A\ AClass 2 circuit wired wiht Class 1 wire or equivalent. /j\ Suitable for use on a circuit capable of delivering not more than 5,000 rms symmetrical amperes, 240V maximum. For SF3202氺氺氺 W models. Suitable for use on a circuit capable of delivering not more than 5,0 rms symmetrical amperes, 480V maximum For SF3204氺氺氺 W models. A Be sure to ground the unit. Ohterwise, there is a danger of clectric shock and/or fire. ^jj Wiring work shall be carried out by electrical experts. Otherwise, there is a danger of electric shock and/or fire. A Implement wiring after checking that the power supply is off. It might incur electric shock and/or fire. A After installing the main body, carry out wiring. Otherwise, there is a danger of electric shock and/or injury. 51 /!\ CAUTION /K 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 50/60 Hz /f\ 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.

Check so that there is no loosening of screws. Otherwise, there is a danger of fire. /j\ 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. /|\ 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. /f\ As for motor leads,
