Before using inverter, always read this instruction manual instruction manual (basic) [IB-0600026] packed with product carefully equipment optimum. This instruction manual uses International System Units (SI). measuring units yard pound system indicated parentheses reference values.
This section specifically about safety matters
attempt install, operate, maintain inspect inverter until have read through instruction manual (basic) appended documents carefully equipment correctly. inverter until have full knowledge equipment, safety information instructions. this instruction manual, safety instruction levels classified into "WARNING" "CAUTION". Assumes that incorrect handling cause hazardous WARNING conditions, resulting death severe injury. Assumes that incorrect handling cause hazardous conditions, resulting medium slight injury, cause physical damage only. Note that even CAUTION level lead serious consequence according conditions. Please follow instructions both levels because they important personnel safety. Electric Shock Prevention
CAUTION
WARNING
While power when inverter running, open front cover. electric shock. inverter with front cover removed. Otherwise, access exposed high-voltage terminals charging part circuitry electric shock. power off, remove front cover except wiring periodic inspection. access charged inverter circuits electric shock. Before starting wiring inspection, check residual voltages with meter etc. more than minutes after power-off. Earth inverter. person involved wiring inspection this equipment should fully competent work. Always install inverter before wiring. Otherwise, electric shock injured. Perform setting dial operations with hands prevent electric shock. subject cables scratches, excessive stress, heavy loads pinching. Otherwise, electric shock. change cooling while power dangerous change cooling while power When have removed front cover, touch connector above 3-digit monitor display. Doing cause electric shock.
Fire Prevention
CAUTION
Mount inverter incombustible material. Mounting near combustible material cause fire. inverter become faulty, switch inverter power. continuous flow large current could cause fire. connect resistor directly terminals P(+), N(-). This could cause fire. Injury Prevention
CAUTION
Apply only voltage specified instruction manual each terminal prevent damage etc. Ensure that cables connected correct terminals. Otherwise, damage etc. occur. Always make sure that polarity correct prevent damage etc. While power some time after power-off, touch inverter brake resistor they burnt. Additional instructions Also note following points prevent accidental failure, injury, electric shock, etc. Transportation installation
CAUTION
When carrying products, correct lifting gear prevent injury. stack inverter boxes higher than number recommended. Ensure that installation position material withstand weight inverter. Install according information Instruction Manual. operate inverter damaged parts missing. When carrying inverter, hold front cover setting dial; fall fail. stand rest heavy objects inverter. Check inverter mounting orientation correct. Prevent screws, wire fragments, other conductive bodies, other flammable substances from entering inverter. drop inverter, subject impact. inverter under following environmental conditions: Ambient -10°C +50°C (14°F 122°F) (non-freezing) temperature Ambient humidity 90%RH less (non-condensing) Storage -20°C +65°C (-4°F 149°F) temperature Indoors (free from corrosive gas, flammable gas, Ambience mist, dust dirt) Maximum 1000m (3280.80feet) above level standard operation. After that derate Altitude, vibration every extra 500m (1640.40feet) 2500m (8202.00feet) (91%). 5.9m/s2 less (conforming C0911) *Temperatures applicable short time, e.g. transit. Environment
Wiring
CAUTION
capacitive equipment such power factor correction capacitor, radio noise filter surge suppressor output inverter. connection orientation output cables motor will affect direction rotation motor. Trial
CAUTION
Check parameters, ensure that machine will damaged sudden start-up. Operation
WARNING
When have chosen retry function, stay away from equipment will restart suddenly after alarm stop. [STOP] valid only when appropriate function setting been made. Prepare emergency stop switch separately. Make sure that start signal before resetting inverter alarm. failure restart motor suddenly. load used should three-phase induction motor only. Connection other electrical equipment inverter output damage equipment. modify equipment.
CAUTION
electronic overcurrent protection does guarantee protection motor from overheating. magnetic contactor inverter input frequent starting/stopping inverter. noise filter reduce effect electromagnetic interference. Otherwise nearby electronic equipment affected. Take measures suppress harmonics. Otherwise power harmonics from inverter heat/damage power capacitor generator. When parameter clear clear performed, each parameter returns factory setting. Re-set required parameters before starting operation. inverter easily high-speed operation. Before changing setting, fully examine performances motor machine. addition inverter's holding function, install holding device ensure safety. Before running inverter which been stored long period, always perform inspection test operation. Emergency stop
CAUTION
Provide safety backup such emergency brake which will prevent machine equipment from hazardous conditions inverter fails.
Maintenance, inspection parts replacement
CAUTION
carry megger (insulation resistance) test control circuit inverter. Disposing inverter
CAUTION
Treat industrial waste. General instructions Many diagrams drawings this instruction manual show inverter without cover, partially open. Never operate inverter like this. Always replace cover follow this instruction manual when operating inverter.

1.5.2 Wiring instructions
insulation-sleeved crimping terminals power supply motor cables. Application power output terminals inverter will damage inverter. Never perform such wiring. After wiring, wire off-cuts must left inverter. Wire off-cuts cause alarm, failure malfunction. Always keep inverter clean. When drilling control etc., take care wire off-cuts enter inverter. cables recommended size make voltage drop maximum. wiring distance long between inverter motor, main circuit cable voltage drop will cause motor torque decrease especially output frequency. long distance wiring, fast-response current limit function reduced devices connected secondary side malfunction become faulty under influence charging current stray capacity wiring. Therefore, note maximum overall wiring length. Electromagnetic wave interference input/output (main circuit) inverter includes harmonic components, which interfere with communication devices (such radios) used near inverter. this case, install optional FR-BIF radio noise filter (for input side only) FR-BSF01 FR-BLF line noise filter minimize interference. install power capacitor, surge suppressor radio noise filter (FR-BIF option) output side inverter. This will cause inverter trip capacitor surge suppressor damaged. above devices connected, remove them. (When using FR-BIF radio noise filter with single-phase power supply, connect input side inverter after isolating <L3> phase securely.) Before starting rewiring other work after performing operation once, check voltage with meter etc. more than minutes after power-off. some time after power-off, there dangerous voltage capacitor.

Counter measures electronic overcurrent protection inverter. Decrease carrier frequency. Note that motor noise increases. Selection Soft-PWM (Pr. makes unoffending. ensure that motor protected against line-to-line leakage currents, recommended temperature sensor directly detect motor temperature. Installation selection no-fuse breaker power receiving side, install no-fuse breaker (NFB) protect primary wiring inverter. Which choose depends power supply side power factor (which changes with power supply voltage, output frequency load) inverter. Especially completely electromagnetic type changes operational characteristic with harmonic currents, need choose little larger capacity.

1.5.7 Regarding noise installation noise filter
Some noise enters inverter causing malfunction others generated inverter causing malfunction peripheral devices. Though inverter designed insusceptible noise, handles low-level signals, requires following general counter measures taken.
